The Research And Design Of Testing And Evaluation For Relay Protection Of Power System

On the basis of analysing protective device,this thesis established the soft level of microprocessor-based relays according to the moduler idea.By constituting'soft protective relay'which can simulate the whole set or some partial function of protection device during the faults in power system on the relay simulation platform based on graphic interface,that can supply the checking and evaluating for protection. This system can proceed real-time on-line simulating,and can also proceed off-line simulating using data from fault recorder,and then it help to study the principles of relay protection and the practical algorithm for functional modue frames,it also can help to check the setting of protective relays.
