Implementation of a real-time distributed network simulator with PC-cluster

This paper describes the implementation of a real-time power system simulator based on a distributed cluster of PC desktop computers. A real-time power system simulator based on a PC-cluster can successfully cope with the size requirements of growing power systems and the computational demands of fast transient studies. The distributed version of OVNI is used as a core solver in addition to a developed I/O interface card. Models based on the standard tool for power systems transients simulations, the EMTP program, optimized for real time performance, assure accurate simulation results
