高压变频器在火电厂凝结水泵上的应用

摘要

介绍深圳妈湾电厂5、6号机组凝结水泵变频改造方案，阐述了高压变频器的安装调试情况及其控制策略，运行结果显示变频改造后电动机节能效果显著。%The article introduces frequency conversion recon-struction scheme of condensate pump for Shenzhen Mawan power plant unit 5, and 6.This paper expounds the installation and debug-ging situation of high voltage frequency converter and its control strategy. Operation results show that the frequency conversion re-construction after motor energy saving effect is remarkable, and im-prove the motor operating conditions.
