Abstract
Recently, there has been growing interest in utilizing cogeneration(COGN) system which has high energy efficiency due to the lacking of energy resource, but insertion of cogeneration system into existing power distribution system can cause several problems such as voltage variations, reenergizing of feeder isolated by fault, increasing fault current because of reverse power of COGN. Also these problems increase the complexity of control, protection, and maintenance of power distribution systems. Hence, some problems according to COGN interconnection operation to power distribution system must be taken into account so that operation and security of power distribution system is not disturbed. This paper deals with momentary voltage variations and fault analysis caused by interconnection operation of COGN.
