Error 143 | [Various software] | SIMPLEFAULT FZ=x% argument is invalid


Relevant software:

PSS®E
PowerFactory


Emitted message:

SIMPLEFAULT command's FZ=x% argument is invalid - the value must be greater than or equal to 0 and less than 100

Description:​

This error indicates that the FZ= argument in a SIMPLEFAULT command is invalid. If FZ= is specified as a percentage (meaning residual voltage during a fault), its value must be a percentage greater than or equal to 0 and less than 100.

The FZ argument specifies the residual voltage as a percentage of the line impedance.

danger

This error will cause the SIMPLEFAULT command to fail and no outputs will be available from this task.

Possible impact:​

  • This task will not complete as the fault cannot be applied to the simulation.

Potential fixes:​

To resolve this error, you need to correct the value of the FZ argument.

  • Edit the SIMPLEFAULT command: Open the Node containing the SIMPLEFAULT command and correct the FZ value.
  • Correct the FZ value: Ensure that the value provided for FZ= is a number between 0 (inclusive) and 100 (exclusive). For example, FZ=10% is valid, but FZ=100% or FZ=-5% are not.
