Features and Improvements
- Auxiliary Files (SCRIPT and DATA Sections): Modified the CloseWithBreakers script command to allow input of a single object instead of a filter. The second parameter can now be the name of an advanced filter or the identifier for a single object of the objecttype that is specified as the first parameter. The single object identifier must be enclosed in square brackets and use the relevant key fields for the objecttype specified. The format for identifying a single object is the same as that used with the Move script command except that the objecttype should not be specified as part of the object identifier. Example: CloseWithBreakers(Gen, [1 "1"], YES);
- Auxiliary Files (SCRIPT and DATA Sections): If loading in an auxiliary file with REMOVED object types, i.e. REMOVEDBUS, REMOVEDBRANCH, etc., the corresponding objects will be deleted in you are in Edit mode. REMOVED object types that are supported are any object that can be compared in the toplogical differences as part of the Difference Flows tool.
- Auxiliary Files (SCRIPT and DATA Sections): Added script command DiffFlowRefresh that will reset the links between the Difference Flows Base case and the Present case. This should be used after a topology change has been made before any results are saved indicating elements that have been added or removed. It would especially be a good idea to use this before using the ContainedInDiffFlowsBC field to determine if an element has been added.
- Case Information Displays: When using the option to display column headers as variable names, the upper left cell in case information displays will now show the objectname of the objects in the table.
- Contingency Analysis Tool: Two new fields were added to the contingency summary that count how many GLOBAL and TRANSIENT actions were applied as part of the contingency.
- Contingency Analysis Tool: Skipped actions will no longer show up as part of the What Actually Occurred summary for a contingency. This is to prevent cluttering the results when many Global Actions exist but are not applied during a particular contingency.
- GIC: Added GIC fields to show the driving point resistance calculation at a substation. This helps in determining the sensitivity of the GIC currents to a change in the substation grounding resistance.
- Auxiliary Files (SCRIPT and DATA Sections): The SendToExcel script command would result in an error if the workbook extension was not specified and the workbook existed. This has been fixed.
- File Formats: When loading a RAW or EPC file, only mark a line with negative reactance as a series capacitor if the line has the same nominal voltages at each terminal.
- File Formats: When loading in a PWB file, corrected lines marked as series capacitors if they do not have the same nominal voltage at each terminal.
- File Formats: When appending an EPC file, update the regulated bus of a generator.
- GIC: Fixed errors on the Unified Transformer display for showing the configuration at the High and Medium bus for two-winding transformers when the "From Bus" wsa not equal to the "High Bus".
- GIC: Fixed error when using copy/paste or loading from an AUX file to update the GIC Unified Transformer data. This was not working properly for some three-winding transformers.
- GIC: Fixed error on the Unified Transformer display with entering data for the winding resistances on a two-winding transformer when the "From Bus" was not equal to the "High Bus".
- GIC: Simulator attempts to automatically determine the existence of three-winding transformers when the input data does specifically specify one by searching for buses connect to three transformers. This search algorithm has been modified so that it will not consider a grouping of three transformer a three-winding transformer if the potential start bus point has any generation or load connected to it.
- Power Flow Solution: Fixed an access violation that could occur if the power flow failed to solve and there were SVCs of type SVSMO2 in the case.
