Abstract

In this paper, the 20kV power network is used as the design concept, and the simulation model of relay protection of single power supply branch is built by using MATLAB/simulink, and the action characteristics of the protection device are monitored by using pan-Boolean algebra. The simulation waveform of the pan-Boolean monitoring model and the waveform obtained from the relay protection simulation model are compared and analyzed to observe the internal action mechanism of the protection device and to understand the action principle of the protection device deeply.
