| This article through summarizing, to the operational principles of line protection and transformer protection, has made certain the protective configuration and the computational scheme of relative technical parameters about the simulations of these two kind of protection.And uses the OOP technology, to the required function of relay protective device, has developed the software proctection simulation system which has graphic interface based on PC system and Windows Operation System, which has fuctions of data acquisition, data display, protective unit configuration, data exchange, etc. And uses the electrical power system model establishing by MATLAB, has made the debugging and the examination to the software protection simulation system.The resualt coming out from that has shown the software protection simulation system can simulate veritably the functions of actual protective devices. |
