Abstract:A static and dynamic simulation testing system based on PC and off line electromagnetic transient program (EMTP) for two terminal protective relaying is presented, in which the simulation data of EMTP is used as the data source. Before the real time test of protective device according to the pre estimated protection action the related data is calculated by EMTP, in the real time test in the light of practical action of the protective device the relevant data is sent to the hardware of the testing system to generate appropriate currents and voltages to implement the closed loop test of multi terminal protection. The structure of the presented system is simple, it does not raise special claim to the hardware and its simulation result is accurate. It is validated that the presented system is an effective way for transient test of protective devices, by which the various action features of protective devices can be implemented.
Keywords:EMTP  protective relaying  transients test
