Research Of Relay Protection Simulation For Power System Based On Object-Oriented Technology

With the development of power system, the development of relay protection is very fast and becomes more and more complicated. So it is very important to develop simulation system of relay protection. According to the demand of simulation of relay protection in this paper, a software system is developed to implement relay protection simulation based on object-oriented technology taken LFP-901A microcomputer protection device for example. The system has built an object-oriented graphic interface of power network and built network model and network database through the graphic interface and implemented functions of the relay set based on the network. The system makes use of modular programming technology for all functions of relay protection and has implemented action behavior simulation and debugging simulation of relay protection which provides a vivid simulating circumstance for users.
