Features and Improvements

  • File Formats: When writing out a GCAP file, now write all the capability curve points instead of only the first 10. Newer versions of this file support up to 20 points now. Messages are written the message log indicating if more than 10 points are being written however.
  • Transient Stability: Added GGOV1DU governor model which is identical to GGOV1 but has up and down deadband limits on the input frequency signal.
  • Bug Fixes

    • Auxiliary Files (SCRIPT and DATA Sections): Fixed bug when writing out RAS and Contigency Definitions to an AUX file in the situation that ModelConditions existed, but there were not any ModelConditionCondition objects. An access violation would occur.
    • Transient Stability: The parameter Vemin was not being properly enforced as a lower limit on the DC4B and DC4C exciter models. This has been fixed.
