Fault Analysis by Using MiPower Software and Circuit Breaker Design

Abstract

Fault analysis on power system is very important and difficult job to find the fault current in different condition. The studies and finding that fault current used to determine the reliability and stability of the power system and used to increase the safety of the system. Fault analysis also called the name short circuit analysis. The fault current values are used to determine the correct rated protective device for the power system. Evaluate the fault current at different scenarios of fault. If the power system is large it’s difficult to find the fault current by hand calculation. In the present project, the power system software is used to find out the fault current virtually at different fault condition. The power system software used in the project is MiPower. The power system software mainly used to found out the fault current in different condition and different location of power system. Different locations are fault at bus and fault at line. For evaluation of the software output, the theoretical calculations are used in the present project. Using this fault current value, the suitable circuit breaker would be chosen and installed on the power system to protect the system from severe fault.
