IPSA (Interactive Power System Analysis) is power system analysis software for modelling and analysing electrical networks, used for load-flow, fault-level, protection, harmonic and transient-stability studies. It originated in research at the University of Manchester Institute of Science and Technology (UMIST) in the 1970s and later became a commercial product.[1]

History

[edit]

IPSA originated at UMIST during the 1970s, applying interactive computing and graphical displays to power-system simulation at a time when such calculations were typically performed in batch-processing systems. Colin Lynch, Alfred Brameller and K. R. Cale described the approach at the 1977 IFAC Symposium in Melbourne.[1] Related protection-modelling work by J. P. Whiting and D. Lidgate, for calculating IDMT relay settings, was published in 1983.[2]

TNEI Services Limited was incorporated on 10 December 1999.[3] In June 2010, Petrofac acquired TNEI Services for a stated consideration of £7.5 million.[4][5] TNEI was bought back from Petrofac in a 2016 management buyout led by Rachel Hodges and Nigel Tate.[6] In July 2026, the IPSA software business became a separate company, IPSA Energy Solutions Limited, wholly owned by TNEI Group.[7][8]

Capabilities

[edit]

IPSA provides a graphical environment for building network models and running load-flow, fault-level, protection and arc-flash, harmonic, transient-stability, unbalanced-load-flow and contingency-analysis studies.[9] A Python interface, PyIPSA, allows models to be built and run programmatically; this was used in a 2019 UCL master's thesis by Owain Jones, which applied IPSA-Power models of real UK distribution networks to study the impact of micro-generation and low-carbon heating.[10] IPSA has also been used as a simulation tool in power-systems textbooks: M. Abdus Salam's Fundamentals of Power Systems (Narosa/Alpha Science, 2009) uses IPSA, alongside PowerWorld, for worked network-simulation examples.[11] IPSA has been tested for compatibility with the Common Grid Model Exchange Specification (CGMES), with version 2.10.2 recorded in an ENTSO-E conformity declaration as tested against IEC 61970-600-1 and IEC 61970-600-2.[12]

Industry use

[edit]

IPSA was used in Project FALCON, a Western Power Distribution low-carbon network innovation project (2012–2015) that trialled alternatives to conventional 11 kV network reinforcement. WPD's final project report describes offline power-flow models built on the TNEI IPSA platform, with Python scripts used to adjust network data, control switch states and run multiple load-flow cases.[13] A 2015 survey of power-system modelling in Great Britain's network companies, prepared by TNEI staff for the Institution of Engineering and Technology, recorded IPSA in use by distribution network operators in one region at 11 kV and three regions each at 33 kV and 132 kV.[14]
