Features and Improvements

  • Transient Stability: In VHVDC1 the Pacref is treated as equal to 0.0 when either converter is blocked. This modification also changes it so that Idcref is also treated as 0.0 when either converter is blocked. This only mattered when using the dPmax and dPmin values to enforce a rate limit on the change in Pacref.
  • Transient Stability: Added the signals 'Iact', 'Ibias', 'Terr', 'IERRinv1' and 'IERRinv2' for the OEL2C model Other Fields.
  • Bug Fixes

    • File Formats: Fixed access violation that would occur when loading an EPC file which contained no Shunt record section.
    • Transient Stability: More robust initialization for OEL2C.
    • Transient Stability: When an OEL model was getting VFE from generators as an input it was not getting the VFE correctly.
