Software History

IPSA

IPSA (Interactive Power System Analsysis) started life as a Ph.D. project at UMIST (now Manchester University) in 1974. It was the first power system analysis software to have a graphical user interface. By 1975 the first version was up and running on an IBM mainframe at MANWEB, and in 1978 work began on the transient stability analysis features. The first commercially available version of the program, IPSA 80, went on sale two years later.
