摘要
本文介绍了两种不同冷却方式在600MW机组一次风机变频节能改造中的应用实例,对空-水冷却系统和密闭冷却系统两种冷却方式进行技术方案和经济效益对比分析,阐述了其中存在的差异和特点。为高压变频节能改造中降低冷却系统能耗,提高系统安全可靠性,提供重要的可借鉴经验。
This paper introduces application of two different cooling in energy-saving reform with inverter in 600MW unit fan. Gives the comparative analysis of technical solutions and economic benefits between air-water cooling systems and closed cooling system, explains the existence of differences and characteristics. This paper provide an important experience to reduce energy consumption, improve system security and reli- ability in the high frequency energy-saving reform.
