Power System Fault Analysis And Simulation

Electrical Engineering and Automation Specialty WANG Min£­jie Abstract: With the wide application of power in all walks of life of national production, has received more and moreattention, so the security and stability of power are crucial. Fault analysis of power system is to solve the power problem, ensuring safe and stable operation of power. Through the example of power system fault analysis. With the help of the three-phase short circuit, may appear on the power system simulation software MATLAB this powerful two-phase short circuit, two phase grounding short circuit, single phase short circuit fault simulation, and the simulation of short circuit voltage, current waveform and the calculated values are compared, analysis. The method using the diagnosis in power system fault analysis, automatic diagnosis, detection can quickly realize the fault, is very important to improve the stability of power system is of significance.
