Warning 131 | [Various software] | Multiple internode values found where one expected


Relevant software:

PSS®E
PowerFactory
PSCAD™


Emitted message:

Internode variable matched to data from linked node - however this node is outputting multiple values for this internode variable and the command only supports one value - the first value will be used

Description:​

This warning indicates that:

  • A command is trying to use an Internode Variable that has resolved to a linked Node
  • The linked Node is exporting multiple values for this variable
  • However, the command where the Internode Variable is being used only supports a single value

The gridmo Engine will use the first value it finds from the linked Node.

danger

This warning indicates that your simulation may be using an incorrect value for a variable, which could lead to unexpected results.

Possible impact:​

  • The simulation will proceed, but it may use an unintended value from the list of available values.
  • This can cause incorrect behaviour or results in the consuming Node.

Potential fixes:​

To resolve this warning, you should investigate why multiple values are being exported for the Internode Variable. The most common cause of this warning is using a dynamic simulation (e.g. PSS®E Dynamic or PowerFactory Dynamic) directly into another dynamic simulation.

If you want to export a single value from a time in a power systems simulation, you will need to use a Plot Node and add an OUTPUT, AT=, NAME= Command into the Plot Node's subplot in order to access a value at a specific time.
