A Emergency Diesel Generator(EDG) in Nuclear Power Plant supplies electrical power to reactor cooling system when on/off site power is lost. So that protect the reactor from melting down. A Emergency Diesel Generator is required to reach ±2% of rated frequency(rotational speed) within 10 sec. To achieve prompt start, it is needed to find out affective factors and effect of that during starting period. This paper describes case of fail to achieve starting requirement and improvement of starting performance.
