Features and Improvements

  • Transient Stability: Modified TSValidation object so they can show the DataMaintainer of the underlying model object.
  • Transient Stability: Renamed the parameter on REGC_C which freezes the PLL state to Vpllfrz.
  • Bug Fixes

    • Transient Stability: REEC_D has input parameter MVABase which specifies the model MVAbase. This impacts the inputs of Pe and Qgen in the model. Typically MVABase=0 which means that the machine MVAbase is used instead. This patch fixes an error when the using line-drop compensation in the REEC_D model to ensure this model MVABase is used if specified.
    • Transient Stability: Fixed error in HYG3 governor model when Cflag>0 and Td=0 with the handling of the ignored state due to Td=0.
