Bug Fixes
- File Formats: Modified the reading of a RAW file so that when a BusType = 4 is read we enforce that this bus is dead after reading the file. We were encountering RAW files with BusTypes that were NOT consistent with the line statuses that were contained in the RAW file. A bus would appear in PowerWorld Simulator to be in a viable and online island due to the fact that the bus was connected by CLOSED branches to online generation. In this situation clearly something is wrong with the consistency of the input data, and previously PowerWorld had obeyed the branch statuses instead of the BusType. This has been modified so that in this situation all branches that connect to the bus marked as BusType = 4 will be opened and an appropriate log message indicating the input file inconsistency will be written. Customers have indicated that this is appropriate treatment when reading a RAW file with inconsistent data.
- GIC: When the GIC Transformer display is being viewed, if you saved the case, an nuisance access violation would occur. This didn't hurt anything and the case info just immediately refreshed, but this nuisance access violation has been fixed.
- Integrated Topology Processing (ITP): When using the option to Apply Selected Contingency, actions involving breakers did not do anything because we were not expanding them into their actual breakers. This has been fixed.
- Transient Stability: Fixed error in reading the LSDT3 model from a DYD file. Some of the columns were read in an incorrect order.
