Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added optional parameter filter to the end of SetSensitivitiesAtOutOfServiceClosest and CalculateTLR script commands to specify a bus filter for the out of service buses that should have their sensitivities set.
  • Auxiliary Files (SCRIPT and DATA Sections): Added script command CTGReadFilePSLF("filename") to read a contingency file in the OTG format.
  • Auxiliary Files (SCRIPT and DATA Sections): Added script command CTGReadFilePTI("filename") to read a contingency file in the CON format.
  • Contingency Analysis Tool: Contingency Limit Violation results including the Value, Limit, and Percent whill show at least 4 significant digits regardless of the decimal places specified by the user.
  • Bug Fixes

    • Transient Stability: When using the Scaled Quadratic Saturation Model for an exciter model, if a value of E1=0 we now automatically ignore the saturation function. The saturation function is B*(E-A)^2/E so if E=0 this function is undefined so this input data does not make sense.
