Effect of distributed generation on distribution systems during faults

With the ever increasing demand for power, the complexity and the cost of transmitting extra high power over larger distances increases. Distributed generation provides a relief for the transmission losses by generating power nearby the load. This paper focuses on the effect of distributed generation on the quality of the system voltages at any concerned location due to various faults occurring on the power system. The location of the DG also has a noticeable effect on the system parameters. This work is also intended to enhance the power quality using techniques to balance the phase voltages. Three phase DG is a 3 phase generator connected to all three phases it supplies both real power and reactive power in order to improve the voltage quality. The Presence of a distributed generator also effects the fault location identification as the voltages and the current at the fault location differ because of the presence of distributed generator, hence proper modification have to be made in the protection system in order to work as designed for. In order to analyze the waveforms simulink/matlab software is used. The result of the project helps us to analyze the quality of power delivered in the presence of distributed generators. There by proper modifications can be done in order that the stability of the systems not affected.
