Study Of Relay Protection Simulation System Based Logic Judgement Method

In order to reduce the debugging work load,raise the development efficiency,and cause the relay protection simulation both to satisfy the timely request and to guarantee that protection simulation has the good fidelity and flexibility,This article proposed that basic principle of the protection simulation is:logic method is used probably in each link of rely protection simulation,under the situation of must use electricity amounts,be going to make the breakdown computation number of times to be least,and the installation computation work load is smallest.In this paper,logic analysis methods about each link of rely protection simulation are studied.Based on the proposed methods,the relay protection simulation models which have nothing to do with the operation mode are developed,the corresponding protection simulation flow is designed,which are applied to the simulation training system of the controlled station, and the accuracy of protection models and simulation method is confirmed through example tests.
