In radial distribution systems, three step current protection, also called overcurrent protection, has been widely used for many years. When distributed generators (DGs) are connected to a radial distribution system, they will have some effects on the traditional overcurrent protection scheme and may lead to false tripping. This paper proposed a new communication supported fast current protection scheme based on the traditional three step current protection. The new protection scheme not only solves most of the problems caused by DGs, but also effectively improves the speed of protection for distribution network with DGs. (4 pages)
