Features and Improvements

  • Contingency Analysis Tool: When auto inserting contingencies and using the Open Breakers action, a new option has been added called "Prevent Identical Breaker Actions". Based on the current topology, this will determine the breakers that will operate for a given contingency. If another contingency is found that will cause the same breakers to operate, the actions from both contingencies will be merged so that only a single contingency is inserted.
  • Contingency Analysis Tool: On the local menu of the Contingencies case information display there is a new option under Insert Special called "Merge Contingencies That Result in Identical Breaker Actions." This will examine existing contingencies that contain either an Open With Breakers or Close With Breakers actions and determine the breakers that will actually operate. If another contingency with Open With Breakers or Close With Breakers actions exists that would cause the same breakers to operate, both contingencies will be merged into a single contingency.
  • Oneline Diagrams: Added the ability to open PSLF DRW files as oneline diagrams in Simulator.
  • Transient Stability: When looking at the zone plot for a DistRelay, hover hints showning the reach percentages were not being calculated to display on the plot correctly.
