| Abstract: | We established a power system simulation model by using SimPowerSystems Block set in Matlab/Simulink, and set the parameters of various components in the model and simulated and analyzed various faults of the power system. The results show that the results are in line with the actual theory and the waveform can be accurately and visually inspect the dynamic characteristics of the power system fault. In addition, by the contrast and analysis between different short circuit faults, we can obtain a result that the threephase short circuit fault is the worst situation in the faults of power system. So this situation should be avoided as far as possible in actual manufacture and life. So it showed that Matlab is a powerful tool for the simulation studies of power system. |
