Key features of the IPSA 3 Series
Key Features of IPSA 3.1
G74 fault modelling
Loads are now coupled with a fault mode that emulates induction machines based either on global settings
in IscAnalysisFL or individual impedence information in IscLoad. Additionally a new option in
IscAnalysisFL allows the transformers to be forced to a maximum tap position to garner minimimum
impedence for fault events.
Scenarios
New scenarios functionality has been added in IscNetwork to allow users to merge multiple scenarios
simultaneously either by providing a list of scenarios to merge, or by setting a maximum date/scenario
ID to merge up to.
Additional functionality has been added to allow users to cascade changes to update not only the current
scenario but also all of the current scenarios child scenarios.
Finally functionality to set the default “Fast Merge” options within the UI can be accessed through PyIPSA.
Additional features
Users can now run network reduction through PyIPSA (using
IscNetwork.RunNetworkReductionin conjunction withIscAnalysisNR).Users can now set/unset the global override on data display styles through PyIPSA - selecting which diagram should provide the data display styles to be used across all diagrams.
Key features of IPSA 3.0
Boundaries and Network Reduction
New tool in IPSA to run a network reduction on the network based on a predefined boundary. These
new boundaries can created and validated to define areas either from a predefined reduced area or by
explicitly definining the boundary busbars, validated to ensure no leakages will occur in the
reduction. The IscBoundary class has been created to facilitate the creation, modification and
validation of boundaries from PyIPSA. The IscEquivalentRadial and IscEquivalentBranch classes
have been created to allow access to the equivalents created in the network reduction.
Scenarios
A large expansion and enhancement of the previous “Versions” functionality of IPSA to Scenarios has
occured. A full PyIPSA interface has been created within IscNetwork to allow the creation,
deletion and modification of Scenarios as well as the comparison of Scenarios in the network. Scenarios
have additionally been given description and date fields and brand new functionality has been included
to Update scenarios, Merge scenarios and revert individual item modifications between one scenario and
another. Additionally users may manage many of their Scenario UI options from the PyIPSA interface.
Advanced Feeder Analysis
New module in IPSA allowing for the creation and simple analysis of Feeder Groups. In particular, new
The tracing of feeder groups from feeder circuit breakers now possible through IscNetwork.RunFeederTrace
and the examination of the feeder group properties and Customer Calculations are exposed to PyIPSA.
Feeder by feeder scaling has been added through the IscGroup instances.
Line Loading calculations have additionally been exposed to PyIPSA through GetLineLoadingPC on
branch items and 3W transformers.
Geographic Map Diagrams
As part of the IPSA extension and refit of the Geographic map diagrams, the ability to create geographic
map diagrams from PyIPSA and to modify their settings have all been added to IscDiagram. This
includes the ability to add and remove maps from Geographic diagram, set the geographic maps server
and/or the style and calculate the lat-long positions from the diagram coordinates and vice versa.
Additionally, new functions to calculate the line length from Geographic diagrams (with or without Maps)
have been added to PyIPSA through IscDiagram.GetGeoLineLength.
IscDrawTools
A new IscDrawTools class has been created in IPSA to allow for the modification of the default
settings used when the User draws their network using the PolyDraw or new TreeDraw algorithm.
Draw Component Symbols
PyIPSA can now be used to draw Branches, Transformers, Breakers and Loads in each of the different draw
styles selectable in the UI through new Draw functions in IscDiagram.
Additional Fixes
Multiple new miscellaneous methods and corrections have been added to PyIPSA. These include, but are not limited to:
Exposed more fault level results to PyIPSA for the
IscSynMachine,IscGridInfeed,IscIndMachineandIsc3WTransformer.Extended data optimisations for
IscTransformerandIscGridInfeedCreating PyIPSA objects will now ensure the provided UID matches the required item type.
PyIPSA draw functions will now connect branches to busbars graphically identically to the UI connections.
Generator scaling groups can now have their scaling factors managed through PyIPSA.
