Features and Improvements
- File Formats: Added a log warning message when appending an EPC file which causes a transformer branch to be converted to a normal branch.
- Transient Stability: Added ability when reading an EXWTGE wind electrical model from a GE DYD file to detect if the EXWTGE record represents an older version of that records format. The EXWTGE record is then read using the older parameter order.
- Transient Stability: Added full support for the LDFR load characteristic model.
- Transient Stability: Added read/write support for the CSTATT model.
- Available Transfer Capability (ATC) Tool: Fixed an error that could occur when running an iterated ATC simulation that involved conditional contingency elements.
- Oneline Diagrams: Fixed access violation that could occur when auto-inserting buses objects using the substation record's latitude/longitude information. An error could occur if not all buses were assigned to a substation.
- Power Flow Solution: Fixed a bug which could cause solution convergence difficulty when allowed discrete switched shunts to switch in the inner power flow loop.
- QV Curve Tool: Modified qvExtraMonitoring file so that the results can be easily identified by the contingency and bus which created the results.
- Transient Stability: Fixed problem with the default numeric format used for showing axis label values.
- Transient Stability: Fixed bug with using the Initialize Reference Angle At Zero option. The bus frequency measurements were not being initialized correctly in these situations which could cause errors in the initial frequencies and also cause problems due to stabilizer feedbacks.
- Transient Stability: Fixed error in initialization of REX exciter model when Xc <> 0.
