The AC/Hybrid Power System Simulator and its Role in System Security

This paper summarizes the results of an investigation into the use of hybrid computer systems for the solution of problems associated with the generation and transmission of electrical power. In particular the study was conducted to determine if hybrid computing techniques could result in the capability of real time, or faster, transient stability studies. It was determined that a special purpose hybrid system could provide simulations of power system transient disturbances 100 times faster than real time.
