摘　　要：以内蒙古华电乌达热电有限公司为例,介绍了华电集团内首套自主研制的高压变频器应用于电动给水泵系统的情况。论述了高压变频器的原理和给水泵变频改造的主要内容。通过统计液力偶合器勺管调节时间和计算汽包水位的时间,确定高压变频器故障后采用联启备用泵方案。通过对现场运行数据的统计和对比,认为改造后节能效果明显,每年可节约电费178.3万元。It introduced the first application of the high voltage converter that independent researched used in feed water pump system in Huadian Group. It included the main principle of high voltage converter and the frequency conversion renovation scheme of feed water pump. By timing the adjusting time of transmit pipe and calculate the drum water level time,a standby pump scheme is adopted after determining the failure of high voltage inverte. Finally,through the statistics and comparison of the on-site operation data,the energy saving effect is obvious after transformation. Annual electricity savings of 1. 783 million yuan. It is worthy to be promoted inside Huadian Group.
