Features and Improvements

  • Integrated Topology Processing (ITP): When determining the Derived Status of a device (branch, gen, load, shunt, etc.) by interrogating the system topology, we will no longer consider a Load Break Disconnect as something which will signify that a device is CLOSED.
  • Integrated Topology Processing (ITP): When determining the Derived Status of a device by interrogating the system topology, we will no longer consider a breaker that is directly in series with a switched shunt as something which will signify that a device is CLOSED (except for that particular switched shunt of course).
  • Integrated Topology Processing (ITP): When determining the Derived Status of a device by interrogating the system topology, we will no longer consider a breaker that is in parallel with another type of branch as something which signifies that a device is CLOSED. This is meant to eliminate the consideration of breakers which represent bypass breakers such as for a series capacitor.
  • Transient Stability: Added ability to store the Transmission Line Relay Model states to hard-drive. Previously these could only be stored to RAM.
  • Bug Fixes

    • File Formats: Fixed a problem when reading back in a PWB file which contained Model Expressions which referenced a Model Filter or Model Condition. This reference would be lost after loading back in the PWB file.
