| Abstract: | A novel project of simulation for distance protection is presented in this paper. The simulation module library in the simulator system of microcomputer protection is established by adopting the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) and MATLAB program, the common modules include boot module, algorithm module and logic processing module etc. The operation logic of microcomputer protection is implemented by LabVIEW. Spot experiments show that this idea suffices for types of relay protection simulation. The method has such advantages as convenient operation, clearly and directly observable. And it can be implemented in teaching, training and be used for ascertaining the cause of the maloperation or misoperation of protective relaying in troubles. |
