摘要：The paper provides a simulation model of IEEE 14 bus system for short circuit studies and analysis of symmetrical fault using MiPower software. At the event of a fault occurrence, short circuit studies are performed to obtain current flow magnitude at different time intervals for a power system until steady state condition is achieved. The paper gives simulation result for the current which flows in different parts of the power system immediately after occurrence of a fault. The data obtained is further used to decide switch gear ratings and circuit breakers and also aids in setting and coordination of protective relays. Further the simulation result provides data regarding the contribution of different power system apparatus to the fault located at different buses in the power system and it gives an efficient, accurate and easy way to analyze symmetrical faults in a given power system.
