摘　　要：介绍了某发电厂凝结水泵"一拖二"变频改造过程,通过现场实践,对改造过程中遇到的问题进行了分析调整,提高了变频器投运有效工作时间,实现了除氧器水位自动控制,以及凝结水泵变频调速和除氧器水位调节阀的协调运行,合理确定了变频器的投入策略,有效降低了厂用电量。The two driven by one frequency conversion is conducted on condensate pump in certain power plant. Practice at site has made for improving effective work duration of inverter, realizing the automatic control of water level, harmonic operation between condensate water pump speed regulation ＆ deaerator water level regulator valves. Reasonable commissioning policy of inverter has been determined, auxiliary power has been reduced effectively.
