摘要
本文介绍了大唐长春第三热电厂350MW机组单元制闭合大回路系统闭式冷却水泵变频改造的方案和实施情况,并对产生的经济效益和运行效果进行了评估。其结论为:变频技术在闭式冷却水泵的应用即实现了全厂冷却水量的安全稳定调节,又达到了节能降耗目的。
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 350 MW unit of closed circuit system of Da Tang 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.
