Advanced Simulation Tool for Relay Testing

Relays usually need to be tested under a variety of fault and non-fault scenarios. In order to better achieve this goal, relay testing simulation tools based on EMTP/ATP combined with MATLAB/C/FORTRAN have been studied by a few researchers. However, there is hardly a relay testing too, designed for PSCAD/EMTDC. An advanced simulation too, based on PSCAD and MATLAB for relay testing is proposed in this paper. The simulation tool can not only batch test relay performance under various scenarios automatically, but also can solve the problem of PSCAD not being able to automatically generate scenarios at different fault locations. Examples are given in this paper to illustrate the application of the proposed simulation tool in relay testing. Tips on how to use the proposed tool for neural network training are also included.
