Features and Improvements

  • Auxiliary Files (SCRIPT and DATA Sections): Added script command PVDataWriteOptionsAndResults("filename", AppendFile, KeyField) that will write out all options and results associated with the PV tool to an auxiliary file. This writes out the same information as PVWriteResultsAndOptions except that it will ALWAYs use the concise variablenames and headers and use DATA sections instead of SUBDATA sections.
  • Auxiliary Files (SCRIPT and DATA Sections): Added Use Concise Format checkbox to the PV saving options dialog when saving to an auxiliary file using the Save Auxiliary button on the PV Curve tool dialog. This will always use the concise variablenames and headers and use DATA sections instead of SUBDATA sections.
  • Auxiliary Files (SCRIPT and DATA Sections): Added script command QVDataWriteOptionsAndResults("filename", AppendFile, KeyField) that will write out all options and results associated with the QV tool to an auxiliary file. This writes out the same information as QVWriteResultsAndOptions except that it will ALWAYs use the concise variablenames and headers and use DATA sections instead of SUBDATA sections.
  • Auxiliary Files (SCRIPT and DATA Sections): Added Use Concise Format checkbox to the QV saving options dialog when saving to an auxiliary file using the Save button on the QV Curve tool dialog. This will always use the concise variablenames and headers and use DATA sections instead of SUBDATA sections.
  • Auxiliary Files (SCRIPT and DATA Sections): Added parameter AppendFile to the QVWriteResultsAndOptions("filename", AppendFile) script command. This is an optional parameter that can be omitted and will be YES by default.
  • Auxiliary Files (SCRIPT and DATA Sections): When saving ATC settings to an aux file either using script commands or the Save Settings button on the ATC dialog, any injection groups that are used with transfer direction definitions will also be saved.
  • Available Transfer Capability (ATC) Tool: Added TransferLimiter field called Report Limit that is YES for the limiter that has the lowest overall Trans Lim value if there are no limiters that were iteratively found or the lowest Trans Lim value for the limiters that were iteratively found. This is the same limiter that is reported in the results table for multiple scenarios.
  • Case Information Displays: For Switched Shunt Case Information Displays added AutoControl field as a default column
  • Time Step Simulation: Time Step Simulation input now has an option to input a values are the scaled based on a combination of the initial value and the variation in another (selected) column. A common example is scaling load in which the desire is to make the load conforming say between areas.

  • Bug Fixes

    • Transient Stability: Fixed a bug with VTGTPAT timers. If the Relay Pickup Time (RelayTP) is more than 30 seconds there were some errors in the timer. This was fixed and now the relay will act in the correct time.
