Fault Level Calculation of Large Inter Connected Power Network

Abstract

Electrical Energy is one of the most important requirement for our current way of living. The target of Electrical power industry is to provide electricity to every com- mercial and household buildings at proper voltage and frequency range. To achieve this target, appropriate electrical network of generators and transformers is needed to be properly connected to the wide network of transmission and distribution lines. In order to achieve the uninterrupted electrical power supply throughout the year, every type of fault and abnormal conditions like mechanical failure ,weather capability of components used in the power system should be considered to tackle these problems. Appropriate fault condition analysis should be carried out to protect the power system under abnormal condition using the circuit breakers, relays and other power system protection equipments. Our electricity consumption is increase day by day. So in future our system is modified like adding transmission line in system or other transformer will put in system .Now a days we focus on renewable energy sources. So our actual system is modified when renewable sources add into system. My project is focus on changes in fault level with renewable energy sources and develop software for calculating the fault level. So from software we will able to calculate new fault level within minutes and we save our time and energy from this tedious job.
