Research on power system fault simulation based on MATLAB
Abstract:This paper introduces the basic operation of MATLAB and Simulink, and the power system fault analysis method. The main contents of the fault on the power system within the scope of the build system simulation model, and illustrates the power system fault problem, especially the various types of short circuit, which carried out the simulation and analysis of three-phase short circuit. In the case of running and referring to these simulation cases, the depth analysis of the simulation results is made. By comparing the simulation results with the results obtained by fault calculation, the conclusions are drawn. Through the simulation case verifies the simulation of power system based on MATLAB is able to run the analysis and design of all kinds of fault in the power system of the computer simulation technique based on MATLAB can be easily carried out, and there is a great prospect.
