Fault Current & Fault Voltage Analysis of Power Distribution Network

Power distribution networks such as distribution substations plays very important role while distributing power to the consumers. Analysis of fault for distribution network of power is very necessary. Fault analysis can be done by various methods such as symmetrical components, MVA method, percentage impedance, percentage admittance method, per unit method. From all these fault analysis method, symmetrical component method is accurate. This method requires less time for calculations. This method is fast as compare to other methods. Here values of fault current and fault voltages at 33 kV bus is calculated with the help of Matlab.
