Features and Improvements
- Case Information Displays: Added new branch fields which allow you to edit line limits in Amps instead of MVA. This only works for non-transformer branches. We only store one set of limit, so this only allows you to edit those limits in different units.
- File Formats: When loading a RAW file, we now automatically flag any non-transformer branch with R=0, B=0, and X<0 as a series capacitor. This is especially important when using the Geomagnetically Induced Currents Add-on (GIC) as series caps will block the DC GIC flows.
- Power Flow Solution: Added error checking for parallel transformers so that if they do not regulate the same bus (actually ZBR Bus group), then the transformer will be turned off control automatically and an appropriate message written to the log
- Transient Stability: For Transient Stability Limit Monitor Violations, extra columns are now available to show the area, zone, owner, substation, nominal kV, labels, bus numbers, bus names, and circuits associated witht he respective violations. This is the same functionality as has always existed in the power flow contingency analysis tool.
- User Interface Dialogs: Modified the list of recently open files so it will dynamically increase the visual width when file names become extremely long so that the entire file name can still be viewed.
- File Formats: When loading an EPC file, changed the default setting of "Sharing of generator vars across groups of buses during remote regulation" so it default so use the SUM OF user-specified remote regulation percentages.
- File Formats: When reading a RAW file, modified to handle bus records which omit the voltage magnitude and angle. If these values are omitted, then we assume a magnitude of 1.0 and an angle of 0.0. Previously it would cause an error when reading the file.
- Help: Fixed a potential problem when invoking the Simulator help. Previously, an extra set of quotation marks were included in the URL passed to the browser which could cause a problem with some browsers. The user would see a strange %22 in the URL when this problem existed.
- Oneline Diagrams: Fixed a possible error when loading the PWD file with Line Flows objects. The Theta angle was set wrong in some Line flows objects. This was causing the arrow to show the wrong direction from the line flow.
- Transient Stability: Fixed bug in which the unlimited SEXS exciter output was being passed to machine models.
- Transient Stability: Fixed limit checking on ignored states for IEET1A and IEEET2 exciters
