Design and realization of real time simulator for substation automation system

Aimed at the difficulties of the substation automation system test, the paper proposes to build a kind of real time simulator designed by the idea of automation equipments functional modularization and introduces its element, structure, function. Used the industrial MCU embedded Windows2000, the device could realize the functions such as mass data test, network delaminating test, device capability test, protect event simulation, protocol test and packet parse etc. The engineering application shows that the device could exactly finish system simulation and device real-time closed loop test and provide an effective way for the substation automation system test.
