Bug Fixes

  • Auxiliary Files (SCRIPT and DATA Sections): Fixed bug with InsertConnectedBuses script command that will not find a data bus if the input is enclosed in quotes.
  • File Formats: Added ability to read ND outages from the CTGL records of the Areva HDBEXPORT CSV files for contingency definitions.
  • General: Fixed bug that would cause "Cannot subscribe to reference notification publisher during destruction" errors.
  • Transient Stability: There is an issue with the way we report the BusNum in Transient stability and the associated Bus Object. The reason for this is when the power flow is set to use the Consolidated Topology Case the Bus object for the Transient Stability is different from the full topology and was affecting the behavior of the script command "TSDisableMachineModelNonZeroDerivative". Now the script command is disabling the machine models in the correct generator with non-zero derivatives.
  • Transient Stability: For TSDisableMachineModelNonZeroDerivative script command treat empty parentheses as having no parameters defined and use the defaults. This had been assuming there was a single blank parameter defined that could not be converted to a floating point value and was producing an error.
  • Transient Stability: When showing transient objects in the All States and State Limit Violations case information displays and using topology processing, the objects were being shown by the consolidated identifying information. This has been fixed to show the full topology identifying information.
  • Transient Stability: Fixed bug on OEL1 exciter in which its violation time was not being property reset so it would instantaneously trip if the current went above the threshold for a second time.
  • User Interface Dialogs: Fixed bug with the Gen Curves that could cause them to not function.
