Warning 124 | [Various software] | Multiple assets matched definition


Relevant software:

PSS®E
PowerFactory
PSCAD™


Emitted message:

Multiple assets matched this definition in the project file

Description:​

This warning indicates that a command in your simulation has tried to reference an asset (e.g. a bus, line, or generator) but multiple assets match the provided definition.

danger

This warning indicates there may be an issue in your model which may cause the simulation to use an incorrect asset. This can impact results and/or benchmarking with other software packages.

Possible impact:​

  • The simulation may proceed using the first asset found that matches the definition. This may not be the asset you intended to use.
  • This can lead to unexpected simulation behaviour and incorrect results.

Potential fixes:​

To resolve this warning and fix the associated issues, you need to make your asset definition more specific.

  • Check for duplicate names: Review your power systems model (e.g. PSS®E .sav, PowerFactory .pfd, or PSCAD™ case) for assets with duplicate names or identifiers. If you find duplicates, rename them to be unique.
  • Use more specific identifiers: When referencing an asset in a command, use a more specific identifier if possible. For example, instead of just using a bus name, you might be able to specify a bus number or a combination of properties that uniquely identifies the asset.
