Summary of the task: An electric power system is a network of electrical components positioned to supply, transfer [transmission and Distribution], and use electric power. Power flow study that provides power to an extended area. An electrical grid power system can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centers to the load centers, and the distribution system that feeds the power to nearby homes and industries. The power is generated at 11kV or 333kVand is stepped up to high voltages of 220kV and 132 kV for transmission. The transmission voltages are to a large extent determined by system loss considerations. High voltage transmission requires conductors of larger cross-section which results in lower resistances, hence less energy losses on transmission lines. The load centers are usually located away from generating stations. Therefore, the power is transmitted to the load centers where it is stepped down to 66kV or 33kV, the distribution level. The load demand determines the voltage at which power is to be supplied. The loads may be residential-industrial -commercial which brings about the peak load and off peak load hours. Power is transmitted from low demand areas to high load demand in the grid network.

The control of generation, transmission, distribution and area exchange is performed from a centralized location. In order to perform the control functions satisfactorily, the steady state power/load flow must be known. The entire system is modelled as an electric network and a solution is simulated using a digital program. Such a problem solution practice is called power or load flow study. The analysis of Power Systems under fault condition represents one of the most important and complex task in Power Engineering. The studies and detection of these faults is necessary to ensure that the reliability and stability of the power system do not suffer a decrement as a result of a critical event such a fault. This course work will conduct analyze the behavior of a system under fault conditions and evaluate different scenarios of faults.

The power flow analysis load flow and faulty study are important and tools involving numerical analysis applied to a power system. The results play a major role in the day to day operation of any system for its control and economic schedule.
