Operator Training Simulator with real-time transient stability analysis

The Operator Training Simulator (OTS) system, which is integrated with a real-time transient stability analysis program, has been in operation at the training center of Hokuriku Electric Power Co. since July, 1990. The developed OTS system achieves real-time transient stability analysis with approximately 100 generator and 400 node power systems by parallel processing performed on a computer system with multiprocessor architecture. This paper outlines the developed OTS system and describes the requirements, design concepts, modeling and parallel calculation method of transient stability analysis and the verification result of the developed transient stability analysis program.
