Abstract :
When a fault occurred in a distribution system, the load center located with distributed generation (DG) will have a significant impact upon protection. And the impact depends on the number, location and size of injected DG. This paper focuses on studying the effect of DG upon conventional protection. Starting with the analysis of the coordination relationship between relays to obtain the capacity requirement for single DG connected to radial distribution system, the calculation is extended to several DGs being interconnected. Examples will be used to demonstrate various issues and solutions.
