The paper introduces the frequency conversion technique modification scheme and the implementation condition of the closed circulating cooling water pump, which is used in the 350MW unit of closed circuit system of DaTang Changchun The 3th Power Plant. And estimates the economic benefits and the operation results. The results show that the frequency conversion technique used in closed circulating cooling water pump can not only realize the safety and stabilization regulation in the whole cooling water, but also realize the purpose of the energy saving.
