摘要
发电厂的辅机设备风机、水泵每年要消耗大量的电能,如能采用变频调速装置取代低效的液力偶合器或定速系统,则能获得巨大的经济效益。本文通过对液力偶合器和变频器两种调速装置的分析及性能比较,说明在风机、水泵类负载推广使用变频调速装置的重要性。
Auxiliary equipment in power plant, such as blowers and pumps, consumes large amount of electrical energy,but it can be improved a lot in terms of energy saving and economic benefits if low efficiency hydraulic fluid coupling or constant speed system can be replaced by frequency controlled drive system. The article illustrates the importance of the frequency controlled drive system in blower and pump application by data analysis.
