PSCAD™
Introduction
The PSCAD™ Node performs electromagnetic transient type dynamic study simulations which are powered by PSCAD™, a 3rd party power systems software.
This Node is typically used for the following:
- Completing dynamic studies (e.g. validating Generator Performance Standards).
- Benchmarking plant models (e.g. comparing the performance of PSS®E and PSCAD™ plant models).
The following PSCAD™ versions are currently supported:
- PSCAD™ v5.0.1+
To enable all Commands and features of the PSCAD™ Node, the smiby
block needs to be added to the PSCAD™ model and be connected at the plant's connection point.
Bring-your-own external grid representation is possible without using smiby
, but would extensive require manual configuration using SET
or CONTROL
Commands and is therefore not recommended.
Launch modes
Two launch modes are supported:
- Standard mode [Default]: Build and run simulation executables using PSCAD™. Standard mode is recommended for most users as it requires no additional configuration.
- Direct (EMTDC™) mode: Build simulation fortran executable using PSCAD™ and run simulation executable directly. Direct (EMTDC™) mode is recommended when running a large number of simulations due to speed improvements.
Direct (EMTDC™) launch mode is only supported for PSCAD™ v5.0.1.
Configure Direct (EMTDC™) launch mode
The configuration of this process is now automatic if you accept during the Engine setup process.
Please contact gridmo support if the automated process reports any errors.
User inputs
Select model
Workspace
Defines the input directory and file name of the PSCAD™ Workspace file, including the .pswx
file extension.
Example:
sunny-solar-farm\SMIB.pswx
File paths are relative to the Engine's 'inputs' directory, as defined by the Engine configuration parameter dirs.inputs
. For example, if dirs.inputs
was set as C:\Users\johnsmith\gridmo\Inputs\
:
Absolute file path | Relative file path (required by gridmo) |
---|---|
C:\Users\johnsmith\gridmo\Inputs\sunny-solar-farm\SMIB.pswx | sunny-solar-farm\SMIB.pswx |
gridmo requires that all relevant PSCAD™ Case files (.pscx
) are located in the same directory or a subdirectory of the PSCAD™ Workspace file (.pswx
). This ensures that the Workspace uses relative file path references to the Case files.
Define simulation
Simulation time
Defines the duration of the dynamic study in seconds.
Example: Run a 30 second dynamic simulation.
30
Customize grid
These controls allow you to define the behaviour of the grid. There are two options:
- None: No additional grid behaviour is incorporated.
- SMIB: The grid is modelled as an infinite bus generator for SMIB studies. One of the following may be controlled in a Node:
- Voltage [p.u.]
- Frequency [Hz]
- Angle [degrees]
To use SMIB control functionality, your PSCAD™ Case file must be configured with the smiby
block.
Voltage
Defines the infinite bus generator voltage throughout the dynamic simulation via the smiby
block. Enter a series of time [s], voltage [p.u.]
pairs. The voltage is linearly interpolated between points. There are two methods for specifying the voltage - absolute
and relative
.
If your PSCAD™ dynamic study uses a linked PSS®E Static Node to set the initial infinite bus voltage, it is often convenient to specify the voltage using the relative
method, since it will utilise the infinite bus generator voltage solution from that specific case.
Specifying absolute voltage
Defines the infinite bus generator voltage throughout the dynamic simulation by specifying absolute voltage [p.u.].
Example: Perform a 15 second dynamic simulation. At 5 seconds, step the voltage from 1.00 [p.u.] to 0.95 [p.u.] in a single rapid step. At 10 seconds, ramp the voltage back up to 1.00 [p.u.] over 2 seconds.

![voltage-absolute-playback-plot](/assets/images/psse-dynamic-absolutev-01bcc33468aa184aa454a62b682f1173.png)
Specifying relative voltage
Defines the infinite bus generator voltage throughout the dynamic simulation by specifying relative voltage [%]. The voltage percentage change is relative to the voltage of the infinite bus generator voltage specified using a SET
Command or as specified manually in the smiby
block (initial conditions parameter page).
Example: Perform a 45 second dynamic simulation. At 5 seconds, step the voltage up 0.05 per unit (pu) in a single rapid step. At 15 seconds, step the voltage down to its initial value in a single rapid step. At 25 seconds, step the voltage down 0.05 per unit (pu) in a single rapid step. At 35 seconds, step the voltage up to its initial value in a single rapid step.
- Example
- Plot
0, 0 pu
4.999, 0 pu
5, +0.05 pu
14.999, +0.05 pu

![voltage-relative-playback-plot](/assets/images/psse-dynamic-relativev-03478285cb79d40fe4ff0d55752c7c47.png)
Frequency
Defines the infinite bus frequency throughout the dynamic simulation via the smiby
block. Enter a series of time [s], frequency [Hz]
pairs. The frequency is linearly interpolated between points.
Example: Perform a 25 second dynamic simulation. At 5 seconds, ramp the frequency up from 50.0 [Hz] to 52.0 [Hz] over 3 seconds. At 15 seconds, ramp the frequency back down to 50.0 [Hz] over 3 seconds.

25, 50
![frequency-playback-plot](/assets/images/psse-dynamic-freqplb-12de947b3ab1ef2962b1cf82919a30db.png)
Angle
Defines the infinite bus voltage phase angle throughout the dynamic simulation via the smiby
block. Enter a series of time [s], angle [degrees]
pairs. The voltage phase angle is not linearly interpolated between points - instead the angle is set to the absolute value at the time specified. The voltage phase angle values specified are relative to the initial angle at the infinite bus - which is typically 0° for SMIB studies.
Voltage phase angle changes are instantaneous. Ramps are not supported.
Example: Perform a 20 second dynamic simulation. At 5 seconds, step the voltage phase angle from 0° to 40°. At 15 seconds, step the voltage phase angle back to 0°.

![angle-playback-plot](/assets/images/psse-dynamic-angleplot-8fbff4f18dc2fbcb54f3dab8dd0bf510.png)
Actions
Defines the Commands which configure the dynamic simulation.
Supported Commands:
- Applied BEFORE PSCAD™ is opened:
- SETFILE: Sets the value of a parameter in an external text or configuration file.
- Applied BEFORE simulation has started:
- SET: Sets the status or value of a network element (e.g. bus, line, generator).
- Applied DURING the simulation:
- CONTROL: Controls a network element.
- SIMPLEFAULT: Applies a simple power system fault.
- MULTIFAULT: Applies a sequence of power system faults.
- VDISTURBANCE: Applies a relative over or under voltage disturbance using a fault or shunt (capacitor).
- VOLT_OSCIL: Completes a voltage oscillation test.
- Old commands (not recommended for new projects):
- Applied DURING the simulation:
- TOVTEST: Completes a Transient Over-Voltage (TOV) test.
- Applied DURING the simulation:
All Action Commands (except SET
and SETFILE
) include the AT=
argument, which specifies the time [s] at which the Command is applied.
SET
and SETFILE
Commands are applied before the PSCAD™ case is built into the simulation executable. Specifying AT=0
will apply the Command at the very first time step once the dynamic simulation has started.
If you specify the value of the AT=
argument beyond the simulation duration (e.g. simulation duration is 20 [s] and AT=25
), the Command will not be applied and a warning will be raised.
Define outputs
Outputs
Defines the output channels of the dynamic simulation. The output channels defined here may be used later for plotting and/or further analysis.
Supported Commands:
- OUTPUT: Outputs a network element's dynamic simulation values as an Internode Variable.
OUTPUT
Commands do not require the AT=
argument because dynamic simulation values are recorded for the entire simulation.
Outputs Description
Defines a short description of the dynamic simulation. This description will appear in the legend of any plot of the data generated by this Node.
Example:
Description here!
Advanced
PSCAD™ version
Defines the PSCAD™ version used for the Node. Defaults to Engine configuration.
PSCAD™ compiler
Defines the PSCAD™ compiler used for the Node. Defaults to Engine configuration.
Distance factor
Defines the distance from the connection point at which disturbances are applied. Allowable values are between 0 and 1, where d=1 applies disturbances at the connection point. The image below shows a Thévenin equivalent of the grid as used in SMIB studies, commonly referred to as the 'infinite source', whereby:
- Vinf: Thévenin equivalent voltage source.
- Zinf: Thévenin equivalent impedance.
- Zf: Disturbance impedance.
- d: Distance factor.
- Vpoc: Connection point voltage prior to any disturbance.
![dFactor](/assets/images/dFactor-66149863aa35c6dbf38a50ad7413e4bc.png)
Distance factor will apply to all relevant Commands in the Node such as:
TOVTEST
VDISTURBANCE
SIMPLEFAULT
MULTIFAULT
Advanced Parameters
Advanced Parameters allow users to configure test details which are not commonly used. Advanced Parameters are often specific to each Node type.
Each line represents a new Advanced Parameter and is entered as a=b
format, where a
is the name of the Parameter and b
is the corresponding value. All Advanced Parameters are set to their default values if they are not included in the Advanced Parameters field.
Example: Set Advanced Parameter, sample.parameter
to a value of 5
.
sample.parameter=5
smiby
block
Background
smiby is a PSCAD™ Definition provided with the gridmo software platform which enables gridmo to easily interface with your PSCAD™ Workspace. smiby is a Thévenin equivalent source, used for SMIB studies, which can be controlled using the Grid controls. A simplified representation of smiby is shown below.
![smiby-simplified](/assets/images/smiby-92b9e0bc064f0d0e022a554d8f50140e.png)
Adding smiby into a model
Step 1: Disable/remove existing external grid representation
Disable or remove the existing external grid representation (if any) at the connection point.
Step 2: Add smiby
Add the smiby block into your PSCAD™ Workspace. Add a single smiby block in the same PSCAD™ Case file (.pscx
) where your existing external grid representation was disabled/removed. The three phase electrical grid connection is on the left hand side of smiby. In your PSCAD™ Case file, connect this to your connection point using the PSCAD™ wire tool. An example of a correctly configured PSCAD™ Case file is shown below.
gridmo requires that the PSCAD™ Case file (.pscx
) which contains the smiby block is first in the list of Case files. If required, right click the relevant Case file and select 'Move Up', as shown below, to move the Case file to the top of the list of Case files.
![smiby-configure-case-files](/assets/images/smiby-move-case-file-up-909af3bd73ac83ad35c628eb79d4df9a.png)
Step 3: Configure control channels
In addition to providing a controllable Thévenin equivalent source, smiby also contains 12 independent multi-purpose control channels which can be controlled using the CONTROL Command. Control channels should normally be used for values which you may want to vary during a PSCAD™ simulation. Examples of common control channels:
- Active power setpoint
- Reactive power setpoint
- Voltage control mode
- Voltage setpoint
- Source energy (e.g. wind speed, solar irradiance)
In your PSCAD™ Case file, connect these control channels to your generating system using the PSCAD™ wire tool and Data Signal Array Tap.
In the smiby parameter window, configure the following settings for each control channel:
- Enable/disable: This defines whether the control channel is enabled or disabled.
- Scale: This defines the scaling applied to any
CONTROL
Commands (i.e. control channel output =CONTROL
Command value x scale). This scale is not applied to the default value. - Defaults: This is the control channel output value used if there are no
CONTROL
Commands for this channel.
Depending on the definition of an externally defined or black-boxed PSCAD™ models, you can use the control channels as parameters by defining the channel with a name and adding the value into the parameters box.
Step 4: Configure smiby parameters
Right click on the smiby
block and navigate to 'Edit Parameters'. In the 'Base values' section, set the following values considering the requirements of your generating system:
- Base voltage (
float
): Connection point base voltage [kV]. - Base apparent power (
float
): Connection point base apparent power [MVA]. - Base frequency (
float
): Base frequency [Hz]. - Project rated active power (
float
): The combined maximum amount of active power that the generating system can deliver at the connection point [MW]. This value is used in combination with plant SCR Commands.
Updating smiby to a new version
Updating smiby may overwrite any of your custom modifications to smiby. In general, we recommend not making any changes to the smiby block or OEM libraries so that newer versions may be accommodated easily.
API Reference
This section details the Commands and Advanced Parameters specific to the Node.
SETFILE
Command
SETFILE, FILENAME=, PARAM=, VAL=
Before PSCAD™ is opened, modifies the FILENAME=
external file by finding the PARAM=
setting and updating its value to VAL=
. Supports basic text formats with delimiters such as comma, space, tab and equals.
Arguments:
- SETFILE
- FILENAME (
str
): Defines the relative input directory and file name of the text file to be modified. - PARAM (
str
): Parameter name. - VAL (
float
orint
orstr
): Parameter value.
The text file specified by the FILENAME=
field is only modified in the copy of the model in the Engine's working directory. It is not modified in the Engine's inputs folder.
Example: Before PSCAD™ has opened, modify the file windy_wind_farm\ppc_settings.cfg
by finding the parameter PPC_Q_ControlMode
and set this value to 200.
SETFILE, FILENAME=windy_wind_farm\ppc_settings.cfg, PARAM=PPC_Q_ControlMode, VAL=200
SET
Command
SET, CNAME/CIID=, PARAM=, [VALSCALE=1], VAL=
Sets the parameter PARAM=
of a PSCAD™ component to the value VAL=
before the start of the simulation. Identify the PSCAD™ component by name (CNAME=
) or iid (CIID=
).
Arguments:
- SET
- CNAME or CIID:
- CNAME (
str
): PSCAD™ 'Name' field of the component to set. - CIID (
int
): PSCAD™ 'iid' attribute of the component to set.
- CNAME (
- PARAM (
str
): Parameter name to set. - VALSCALE (
float
)[Optional]: Multiplicative scaling factor applied to theVAL
(i.e.VAL
xVALSCALE
). Default value is 1. - VAL (
float
orint
orstr
): Value to apply to the parameter.
Example: Before the dynamic simulation, set the positive sequence leakage reactance of the two-winding transformer with name MainTX
to 0.12 [p.u.].
- Using right-click and
View Properties
on the main transformer block, the positive sequence leakage reactance has parameter nameXl
.
SET, CNAME=MainTX, PARAM=Xl, VAL=0.12
Example: Before the dynamic simulation, set the LVRT Detection Threshold
setting of the unnamed Simple_PPC block to 0.82 [p.u.].
- Using right-click and
View Properties
on the Simple_PPC block, theLVRT Detection Threshold
has parameter nameLVRT
. - Using right-click and
Attributes
on the Simple_PPC block, theId
field reads1955742872
.
SET, CIID=1955742872, PARAM=LVRT, VAL=0.82
Example: Enable winding saturation (which is a drop-down combo box) for the transformer with name MainTX
.
- Using right-click and
View Properties
on theMainTX
transformer block, theSaturation Enabled
field is aChoice
type parameter. TheChoice
type parameter uses an integer to select the value of the drop-down. Typically, disabled is0
and enabled is1
- but this is not always the case. - Using right-click and
Edit Parameters
on theMainTX
transformer block (combined with theView Properties
window) we can see that the parameter with nameEnab
is0
when saturation is disabled and1
when saturation is enabled.
SET, CNAME=MainTX, PARAM=Enab, VAL=1
The smiby
block's initial conditions can be set using the same Commands as above. The most common Commands have been added below for convenience:
Set the initial slack bus generator voltage [p.u.] (initial voltage of infinite bus):
SET, CNAME=smiby, PARAM=vinf, VAL=value
Set the initial slack bus generator angle [degrees]:
SET, CNAME=smiby, PARAM=ainf, VAL=value
Set the SCR and X/R of the equivalent network impedance. Note if the CONTROL,CH=SCR,
or CONTROL,CH=XR
Commands are used, these values are overridden by those Commands.
SET, CNAME=smiby, PARAM=scr_in, VAL=value
SET, CNAME=smiby, PARAM=xr_in, VAL=value
CNAME
: Finding a component name
The name of a component in PSCAD™ (to use in the CNAME=
) field can be found by right-clicking on a component and selecting View Properties
. Look for a value in the first column which is equal to Name
.
Not all PSCAD™ components have a Name
property. Consider using the iid option if there is no name field.
CIID
: Finding a component iid
The unique identifier of a PSCAD™ component (the iid, used in the CIID=
parameter) can be found by right-clicking on a component and selecting Attributes
.
The Id
field will have a long series of integers. This value is the IID.
Consider only using the CIID
parameter if there is no name parameter for a PSCAD™ component.
If iid needs to be used, consider defining a Global Variable for the iid instead of specifying it in multiple places.
PARAM
: Finding a parameter name
The parameter name of a component in PSCAD™ (to use in the PARAM=
) field can be found by right-clicking on a component and selecting View Properties
.
Click on the Caption
field you are interested in controlling. The parameter name can be found in the first column of the highlighted row.
CONTROL
Command
CONTROL, CH=, [VALSCALE=1], AT=, VAL/RELVAL=
Controls the smiby
control channel with number CH=
to the value of VAL=
at AT=
seconds after the start of the simulation.
Arguments:
- CONTROL
- CH (
int
): Options:CH=1
toCH=12
: Control asmiby
channel (between 1 to 12).CH=SCR
: Control the equivalent Thévenin impedance based on the Project's rated active power [MW], the line voltage and the specified SCR and X/R ratio.CH=XR
: Control the equivalent Thévenin impedance based on the Project's rated active power [MW], the line voltage and the specified SCR and X/R ratio.
- VALSCALE (
float
)[Optional]: Multiplicative scaling factor applied toVAL
orRELVAL
(i.e. new_value =VAL
xVALSCALE
or new_value = old_value + (RELVAL
xVALSCALE
)). Default value is 1. - AT (
float
): Time at which the Command is applied during the dynamic simulation [s]. - VAL or RELVAL:
- VAL (
float
): New value, expressed absolutely (i.e. new_value =VAL
).CH=SCR, VAL=INF
combination controls the equivalent Thévenin impedance to the minimum impedance value applicable in PSCAD™ (i.e. 5e-4). - RELVAL (
float
): New value, expressed relatively (i.e. new_value = old_value +RELVAL
).
- VAL (
CONTROL, CH=SCR, AT=0, VAL=
and CONTROL, CH=XR, AT=0, VAL=
Commands are typically used in conjunction. These are typically only used in SMIB studies and are used to calculate the Thévenin equivalent source impedance of the Thévenin equivalent generator.
Any VALSCALE
scale factors are applied in addition to any scale factors defined in smiby's output channels.
Setting CH=SCR, VAL=
beyond 1e6
may result in unstable PSCAD behaviour, by collapsing all impedances to zero sequence branches. This may cause all faults to be of the same residual depth, regardless of FZ=
. To model infinite system strength conditions, we recommend using CH=SCR, VAL=INF
.
Only the CH=SCR
and CH=XR
control channels are linearly interpolated between points. All other smiby
control channels (i.e. CH=1
through CH=12
) are not linearly interpolated between Commands.
Example:
- Assumes:
smiby
is in the PSCAD Workspace and channel #1 has been connected to the generator under test's active power control port.- The
Scale (when enabled)
field for channel #1 has been set based on the generator under test's active power control scale (e.g. if per unit control, then scale is1
).
- At 5 seconds, set active power to 0.5 [p.u.] of maximum power
- At 15 seconds, set active power to 0.0 [p.u.] of maximum power
- At 25 seconds, set active power to 1.0 [p.u.] of maximum power
CONTROL, CH=1, AT=0, VAL=1
CONTROL, CH=1, AT=5, VAL=0.5
CONTROL, CH=1, AT=15, VAL=0
CONTROL, CH=1, AT=25, VAL=1
Example: Repeat the above example, using relative control steps instead of absolute. This is useful if the initial value is an Internode Variable (as shown below).
CONTROL, CH=1, AT=0, VAL={{i_initial_voltage_setpoint_which_might_not_be_1}}
CONTROL, CH=1, AT=5, RELVAL=-0.5
CONTROL, CH=1, AT=15, RELVAL=-0.5
CONTROL, CH=1, AT=25, RELVAL=+1
Example: Simulate a change in system strength and X/R ratio (simulating a control trip of a remote line) from SCR=10
and XR=4
to SCR=8
and XR=3.6
10 seconds after starting the simulation.
CONTROL, CH=SCR, AT=0, VAL=10
CONTROL, CH=XR, AT=0, VAL=4
CONTROL, CH=SCR, AT=9.9999, VAL=10
CONTROL, CH=XR, AT=9.9999, VAL=4
CONTROL, CH=SCR, AT=10, VAL=8
CONTROL, CH=XR, AT=10, VAL=3.6
Set the system strength of smiby
to infinite (as low as possible) for this simulation.
CONTROL, CH=SCR, AT=0, VAL=INF
SIMPLEFAULT
Command
SIMPLEFAULT, AT=, DURATION=, [TYPE=3PH, FZ=0, XR=3]
Applies a simple fault within the smiby
Thévenin equivalent source impedance.
SIMPLEFAULT
is for use in SMIB studies for simpler fault-related performance studies.
More realistic fault scenarios (e.g. including different clearance times and multi-shot auto-reclose), as required in wide area network studies, are not currently supported.
Arguments:
- SIMPLEFAULT
- AT (
float
): Time at which the fault is applied during the dynamic simulation [s]. - DURATION (
float
): Fault duration [ms]. When the duration has expired, the fault is removed and the line will remain in service. - TYPE (
str
)[Optional]: Fault type. Defaults to3PH
. Options:TYPE=3PH
: Three phase fault.TYPE=3PHG
: Three phase to ground fault.TYPE=2PHG
: Two phase to ground fault.TYPE=PHPH
: Phase to phase fault.TYPE=PHG
: Phase to ground fault.
- FZ [Optional]: Fault impedance. Default value is 0 Ω (i.e. bolted fault). There are two methods for specifying the fault:
- Fault impedance (
float
): Fault impedance [Ω] (e.g.0.2
). - Residual voltage (
str
): Residual voltage [%] (e.g. 20%). The percentage is relative to the nominal voltage. This method is used in SMIB studies. Residual voltage is applied by adding series impedance into the fault path. This impedance is calculated assuming a three-phase fault, but only the relevant phase(s) are faulted in the simulation.
- Fault impedance (
- XR (
float
)[Optional]: Reactance to resistance ratio of the fault. Default value is 3.
Using TYPE=PHPH
and FZ=X%
(residual voltage) will not result in the expected residual voltage during the fault.
Example:
- Assumes
smiby
block has been configured with the correctSCR
,XR
and output active and reactive power correctly for the test usingCONTROL
Commands. - At 5 seconds, apply a fault at the connection point of the generator under test.
- Fault duration is 430 ms.
- Fault type is two phase to ground.
- Fault impedance is Zf=10 [Ohm].
- X/R ratio of the fault is 3.

- Fault impedance is 0 [ohms].
Note FZ=0, XR=3, DISTANCE=0%
have been omitted, as these are the default values.

Applies a pre-defined multiple fault sequence in one Command within the smiby
Thévenin equivalent source impedance.. The first fault is at AT=
seconds. Fault X/R ratio and fault distance percentage can also optionally be provided.
MULTIFAULT
is typically used in SMIB studies for simple one-Command multiple-fault ride-through (MFRT) studies. For more realistic fault scenarios, as required in wide area network studies, we recommend using the ADVFAULT
Command.
Arguments:
- MULTIFAULT
- AT (
float
): Time at which the first fault in the sequence is applied during the dynamic simulation [s]. - TYPE (

MULTIFAULT, AT=5, TYPE=AEMODMAT, SEQ=S1
TOVTEST
Command
TOVTEST
Command is no longer recommended for new Projects. Instead, use the VDISTURBANCE
Command.
TOVTEST, AT=, QCAP=, DURATION=, [TARGET=]
Completes a Transient Over-Voltage (TOV) test within the smiby
block whereby a fixed shunt (capacitor) is switched in service on the connection point of QCAP=
MVAr, AT=
seconds into the dynamic simulation. The capacitor is removed after DURATION=
milliseconds.
Arguments:
- TOVTEST
- AT (
float
): Time at which the Command is applied during the dynamic simulation [s]. - QCAP (
float
): Options:QCAP=X
(whereX
is a number): Size of the capacitor to switch in [MVAr].QCAP=CALC
: Enables the automatic calculation of the capacitor size to achieve a target overvoltage based on theTARGET=
Argument. Any contribution from the generator under test is not included in this calculation.
- DURATION (
float
): Disturbance duration [ms]. When the duration has expired, the capacitor is removed. - TARGET (
float
)[Optional]: Voltage target in per unit for this test. Only required ifQCAP=CALC
.
Only one TOVTEST
Command is supported in a single PSCAD™
Node.
Example:
Assuming smiby
is in the PSCAD™ Workspace, at 10 seconds switch in a capacitor of 15 MVAr at the connection point which, based on the SCR and X/R ratio, gives a TOV of 1.15pu. Switch the capacitor out again after 0.9 seconds.
TOVTEST, AT=10, QCAP=15, DURATION=900
Example:
Assuming smiby
is in the PSCAD™ Workspace, at 5 seconds switch in a capacitor large enough to achieve a 1.2 pu over-voltage at the smiby
connection point, given the SCR and X/R ratio loaded into the smiby
block. Switch the capacitor out again after 0.5 seconds.
TOVTEST, AT=5, QCAP=CALC, TARGET=1.2, DURATION=500
VDISTURBANCE
Command
VDISTURBANCE, [OP=VDIVIDER/COMPENSATED], AT=, DURATION=, VCHANGEPU/VPU=, [XR=3]
At AT=
seconds after the start of the dynamic simulation, applies a voltage disturbance at the smiby connection point. Depending on the values of VCHANGEPU/VPU, OP and the connection point bus voltage prior to the disturbance, the Command automatically switches between:
- Applying a 3PH fault to create an undervoltage disturbance; or
- Inserting a capacitor to create an overvoltage disturbance.
The disturbance is removed after DURATION=
milliseconds.
Arguments:
- VDISTURBANCE
- OP (
str
)[Optional]: Calculation methodology. Defaults toOP=VDIVIDER
. Options:OP=VDIVIDER
: Voltage divider calculation methodology.OP=COMPENSATED
: Voltage divider calculation methodology extended to consider generating system contribution prior to voltage disturbances.
- AT (
float
): Time at which the Command is applied during the dynamic simulation [s]. - DURATION (
float
): Disturbance duration [ms]. When the duration has expired, the disturbance is removed. - VCHANGEPU or VPU:
- VCHANGEPU (
float
): Relative voltage disturbance [p.u.]. The voltage is relative to the smiby connection point bus voltage prior to the disturbance. - VPU (
float
): Absolute voltage disturbance [p.u.].
- VCHANGEPU (
- XR (
float
)[Optional]: Reactance to resistance ratio of the 3PH fault impedance used for undervoltages. Default value is 3. When inserting a capacitor for overvoltage disturbances, XR is ignored.
Multiple VDISTURBANCE
Commands are supported in a single Node, which may include a mix of under and over voltage disturbances.
If you are benchmarking with PSS®E Dynamic VDISTURBANCE
Command, ensure that smiby distance factor is 1.
Calculation methodology
The image below shows a Thévenin equivalent of the grid as used in SMIB studies, commonly referred to as the 'infinite source', whereby:
- Vinf: Thévenin equivalent voltage source.
- Zinf: Thévenin equivalent impedance.
- Vpoc: Connection point voltage prior to any disturbance.
The VDISTURBANCE Command introduces a fault impedance, Zf, in order to achieve a desired voltage disturbance as specified by VCHANGEPU or VPU. There are two calculation methodologies used to calculate Zf:
OP=VDIVIDER
; andOP=COMPENSATED
.
- OP=VDIVIDER
- OP=COMPENSATED
![vdisturbance-vdivider](/assets/images/vdisturbance-vdivider-8f77197d04553575446881082a8fd5d4.png)
Zf is calculated using voltage divider circuit theory. The formula assumes that the generating system current contribution prior to the disturbance is ≈ 0 (i.e. Vpoc ≈ Vinf) and the generating system current contribution during the disturbance is ≈ 0.
![vdisturbance-compensated](/assets/images/vdisturbance-compensated-c2377ee5b66160ce36b3665eb07f0139.png)
Zf is calculated using an extension of the voltage divider circuit theory which consider generating system contribution prior to voltage disturbances. The formula assumes that the generating system current contribution during the disturbance is the same as prior to the disturbance. This methodology is useful when studying generating systems that have a very low SCR and therefore the assumption of Vpoc ≈ Vinf is no longer valid. Consider the example where a generating system is at PmaxQmax with a low SCR and therefore Vinf = 1.2 [p.u.] to achieve Vpoc = 1.0 [p.u.]. If the user requires a voltage disturbance of 1.2 [p.u.] (i.e. Vtarget = 1.2 [p.u.]), using simple voltage divider circuit theory Zinf would be equal to ∞ and no disturbance would be created!
Example:
Assuming smiby
is in the PSCAD™ Workspace, at 5 seconds, apply a 430 ms voltage disturbance at the connection point. The voltage disturbance should cause a -0.1 p.u. relative change in the connection point voltage by applying a 3PH fault.
VDISTURBANCE, AT=5, DURATION=430, VCHANGEPU=-0.1
Assuming smiby
is in the PSCAD™ Workspace, at 5 seconds, apply a 500 ms voltage disturbance at the connection point. The voltage disturbance should target 1.2 p.u. at the connection point voltage by switching in a capacitor.
VDISTURBANCE, AT=5, DURATION=500, VPU=1.2
Assuming smiby
is in the PSCAD™ Workspace, at 5 seconds, apply a 500 ms voltage disturbance at the connection point. The voltage disturbance should target 1.2 p.u. at the connection point voltage by switching in a capacitor.
Assuming smiby
is in the PSCAD™ Workspace, at 10 seconds, once the previous disturbance has cleared, apply another 500 ms voltage disturbance at the connection point. The voltage disturbance should target 0.35 p.u. at the connection point voltage by applying a 3PH fault.
VDISTURBANCE, AT=5, DURATION=500, VPU=1.2
VDISTURBANCE, AT=5, DURATION=500, VPU=0.35
VOLT_OSCIL
Command
VOLT_OSCIL, START_T=, END_T=, MAG=, FREQ=, [PSOMAG=0]
Oscillates/modulates the infinite voltage source within the smiby
block, using a sinusoidal waveform of peak to peak magnitude MAG=
at an oscillation frequency of FREQ=
. The oscillation is enabled between START_T=
seconds and END_T
seconds from the start of the simulation.
Arguments:
- VOLT_OSCIL
- START_T (
float
): Time at which the oscillation starts during the dynamic simulation [s]. - END_T (
float
): Time at which the oscillation ends during the dynamic simulation [s]. - MAG (
float
): The peak to peak magnitude of the voltage oscillation [p.u.]. - FREQ (
float
): The frequency of the oscillation [Hz]. - PSOMAG (
str
)[Optional]: Sinusoidal oscillation of the infinite bus angle (oscillates the source phase angle) centered about0
degrees, with oscillation frequency ofFREQ
Hz. Defaults to 0 (no oscillation).
If a VOLT_OSCIL
Command is used, the Grid controls functionality is disabled within the same PSCAD™
Node.
Only one VOLT_OSCIL
Command is supported in a single PSCAD™
Node.
When using the VOLT_OSCIL
Command, you may observe that the magnitude (amplitude) of oscillation decreases with increasing oscillation frequency. This can be caused by low sampling frequency in any digital multimeter object/block which is measuring the RMS voltage using digital mode. The Frequency
selection under Parameters
may need to be set much higher (up to 1000 Hz, rather than 50 or 60 Hz) to produce a clean output oscillation signal. At higher sampling rates, the magnitude is now identical between frequencies.
The smiby
built-in voltage multimeter has been configured for this purpose.
Example:
Assuming smiby
is in the PSCAD™ Workspace, modulate the infinite voltage source starting at 5 seconds and ending at 15 seconds. Frequency of 1 Hz. Magnitude of 0.005 [p.u.] (0.5%). Vary the phase angle of the voltage modulation using a sine function (2 degrees at the same frequency of 1 Hz).
VOLT_OSCIL, START_T=5, END_T=15, MAG=0.005, FREQ=1, PSOMAG=2
OUTPUT
Command
The OUTPUT
Command is used to output channels so they can be processed or displayed by a Plot
node.
OUTPUT, TITLE=, [VAL=PQS, VALSCALE=1], NAME=, [LEGEND=]
Outputs a variable from a PSCAD™ output channel block.
Arguments:
- OUTPUT
- TITLE (
str
): The 'Title' field of the PSCAD™ output channel block to record. TheTitle
is displayed in text under the output channel block in PSCAD™. - VAL (
str
)[Optional]: The type of output channel. Specifying the correct value for the output channel will result in more accurate auto-scaling for connectedPlot
Nodes. Options:VAL=PQS
: Active power [MW], reactive power [MVAr] or apparent power [MVA].VAL=V
: Voltage [p.u.].VAL=F
: Frequency [Hz].VAL=ANGLE
: Angle [degrees].VAL=I
: Current [p.u.], active current [p.u.] or reactive current [p.u.]VAL=BINARY
: Binary outputs, such as LVRT/HVRT trigger flags.VAL=PF
: Power factor [unitless]. Click here for details on how gridmo calculates power factor.
- VALSCALE (
float
)[Optional]: Multiplicative scaling factor applied to the output value (i.e. scaled_output =VAL
xVALSCALE
). Default value is 1. - NAME (
str
): Output name. Output names must be unique within a Node. - LEGEND (
str
)[Optional]: Subplot legend name. Default value is no legend name.
Example: Output the channel below and name the channel i_p_at_poc
for use by other Nodes, such as a Plot
Node.
OUTPUT, TITLE=P_POC, VAL=PQS, NAME=i_p_at_poc
Example: Output the channel below which is connected to a wind turbine's high voltage ride-through flag output. Name the channel i_hvrt_flag
for use by other Nodes, such as a Plot
Node.
OUTPUT, TITLE=WTG_FRT_HV, VAL=BINARY, NAME=i_hvrt_flag
gridmo uses the 'Title' field of the PSCAD™ output channel block (even if it is greyed out). Depending on the PSCAD™ file configuration, selecting "Use Signal Name as Title?" as "Yes" may not always insert the desired Title. Please double check that the 'Title' parameter value is as expected.
![pscad-output-channel-title](/assets/images/pscad-output-channel-title-b108564452f8b0d06a8d3d58ef8f711a.png)
Any PSCAD™ output channels not defined by an OUTPUT
Command will not be recorded by PSCAD™. You must specify all required output channels.
By defining only the required output channels, this results in faster simulations.
