Ipsa 2 User Interface

Ipsa boasts a comprehensive range of user interface features designed to enable the fast and accurate analysis of power systems.

Diagrams can be created directly using standard drawing tools and procedures. A variety of symbols can be used for network components; for example busbars can be shown as vertical or horizontal lines of any size, or as circles, or dots, or even hexagonal shapes.

Labels on the diagram can show the name of the network item and the results of calculations. The user is given full choice over how results are displayed; for example after a fault level calculation either phase components or sequence components can be shown, to a given number of decimal places, with configurable units.

Colour can be used to show voltage level or to highlight results (such as overloaded components), or both.

Every network component has it's own dialog, designed to make the individual entry of data as easy as possible. Network data can also be entered through tables, with full copy, paste and fill options supported.




Ipsa features a wide range of components providing the flexibility to model virtually all modern power system devices. In addition a comprehensive component database is provided with Ipsa to allow the rapid and accurate construction of network models.

In addition it is possible to specify custom extended data onto each component that can be searched and used in reporting and bespoke analysis.

The tabular displays of component data and results in Ipsa can be copied and pasted directly into spreadsheets; likewise spreadsheet values can be pasted into data tables.  Access to the tables is also available through scripting.

Network Management

The import and export of data and results is critical in modern power system analysis.  Ipsa 2 has been designed to make the exchange of information both simple and flexible.

A separate optional Network Manager module provides multi-user access to a single network database.  Any size of network can be accommodated allowing corporate wide access to the power system model.  The Network Manager is primairly intended for wide area HV distribution networks.  Analysis and network editing can be undertaken on subsections of the full model using the normal Ipsa user interface.


Custom Reporting and Bespoke Analysis

Ipsa 2 uses the Python scripting language to allow rapid development of custom reports and bespoke analysis.  These can be pre-prepared by the Ipsa support team to the client requirements, or developed by the user themselves.

Such additional analysis can be based on the core Ipsa data models as well as using additional extended datasets.  Examples of analysis that can be performed include:

  • Time of Day analysis
  • Debut method
  • Adequacy based reliability
  • Calculation of CIs and CMLs
  • Bespoke assessment of PV and Heat Pump impact

The use of the scripts provides the means to automatically create Excel© spreadsheets or Word© documents, links to external databases as well as refreshing network data including loads and switch status.

Network Versioning

Ipsa 2 features a powerful version control system that allows the user to manage changes in network data.  The system is designed to be used in two ways.

  • Timeline Based - In a timeline-based system where each version represents the network at a particular date in time.  By selecting a particular date, and hence version, the network can be viewed as it was, or as it is expected to be.
  • Scenario Based - In a scenario-based system, each version represents a different operating condition, or a possible change to the existing network.  These versions can be re-examined at a later date, or used to produce a new “base” network model once the modelled changes have been approved and implemented.

Differences between different versions can be reported, as can the difference between the current network and any version.
