Bug Fixes

  • File Formats: Added error checking when loading a hdbexport CSV when some windings of a 3-winding transformer can not be read because the terminal buses of one winding were equal. This is now handled gracefully and the grouping of three-winding transformers parts is ignored. Previously it was causing the software to crash when loading this case.
  • File Formats: When loading an EPC file and creating a 2-terminal VSCDCLine, if the EPC file had a status = 0 on either VSC Converter or the DC Line then the status of the VSCDCLine in PowerWorld should be read as OPEN. Previously all VSCDCLines were being read as closed. This has been fixed.
