Features and Improvements

  • File Formats: Added FaultType for BusFault and LineFault when reading a Transient OTGD file.
  • Transient Stability: Added support for the model WTGIBFFR_A. This model is a Paux controller which is initiated for under-frequency events and plays into the Paux input on various governor and exciter (electrical control) models. In particular it is intended to be played into the REEC_D model for wind turbine models. The model can also be read and written to the DYD format.
  • Bug Fixes

    • File Formats: When reading an OTGD transient file for elements that happened at the same time but a parameter (for example in a branch opening then NEAR and FAR End at the same time) was different it was not adding the event correctly. This has been fixed.
