Features and Improvements
- Contingency Analysis Tool: Added new contingency generator actions to Set To or Change By Mvar. When this action is used the generator will be turned off AVR. These types of actions are not saved in the version 17 PWB file because of compatibility issues. However, these action types can be saved in an auxiliary (AUX) file.
- File Formats: Added file parser to read in EMS exported case as a text file from ABB EMS systems.
- Oneline Diagrams: Added ability to link to a bus view or substation view from a Oneline Link. To use the feature, populate the File or Action string with the keyword BUSVIEW or SUBVIEW along with the number, name_kv, or label of the bus or substation that should open in the appropriate view.
- Oneline Diagrams: Added option to resize buses based on the stub size when using the feature to automatically add lines when inserting connected buses. This option is found under Insert Connected Buses --> Then Auto Insert Lines... from the right-click menu of a bus while in Edit Mode. A dialog prompts the user about whether or not to automatically resize the buses. If user clicks NO, then it will resize the bus based on the number of incident lines. If the user clicks YES, the buses will be resized based on the stub size. This is the default and could, but could cause the buses to get excessively large.
- Oneline Diagrams: Added ability to open bus or substation view onelines from oneline fields and other oneline objects. The bus view oneline will open to the bus that the device is connected to. The same ability has been added for the Quick Power Flow List.
- PV and QV Curve (PVQV) Tool: Added ability to have plotting based on actual value, deviation, percent of the initial value, or percent deviation from the initial value.
- Transient Stability: Added ability to have plotting based on actual value, deviation, percent of the initial value, or percent deviation from the initial value.
- Transient Stability: Added new script command TSRunUntilSpecifiedTime(ContingencyName, [StopTime, StepSize, StepInCycles, ResetStartTime, NumberOfTimeStepsToDo]). The script command emulates what is done in the user interface. A time or number of steps may be specified and the transient stability will run until the specified time or for the specified number of time steps. StopTime should be entered in seconds. StepSize should be entered in either seconds or cycles depending on the StepInCycles field. StepInCycles should be YES if the stepsize is specified in cycles and NO if specified in seconds. ResetStartTime is either YES or NO and indicates if the simulation should be reset to the start time of the contingency. If the NumberOfTImesStepsToDo > 0 then only the specified number of time steps will be done regardless of the StopTime.
- Bus View and Substation View Onelines: Fixed an error in when deleting the bus shown in the bus view. The bus view would not update properly and could produce an access violation. Now an empty view will be shown when the bus is deleted.
- Retriever: Fixed a bad default setting for the temporary retrieval directory. By default, the temporary retrieval directory was set to the same directory as the data file for a flat text data source. This was causing a locked files and failed retrievals when there are multiple Retriever clients accessing the data source over the network drive. The new default stored the temporary file on the local disk.
- Sensitivity Calculations: Fixed an access violation that could occur if calculating TLRs for interfaces.
- User Interface Dialogs: Fixed error that caused some toolbars to remain disabled when loading an AUX case.
