2×600MW电动给水泵两用一备运行方式下变频器改造运行的研究与应用

Discussion and Demonstration on Transformation of Down Converter Operation Mode of Dual-purpose and One standby Operation Mode of 2×600MW Electric Feed Pump

本文是针对双机组或多机组同时运行情况下,电动给水泵变频改造方式的探讨:一种情况为一台机组改一台给水泵、两个机组一共改两台给水泵,另一种情况为两一台机组改两台给水泵,这两种运行方式通过多个方面进行论证、分析以及本文给出了最终的结论。

This paper discusses the frequency conversion transformation mode of electric feed pump when two or more units operate at the same time:one case is that one unit is changed to one feed pump,two units are changed to two feed pumps,and the o ther case is tha t two unit s are changed to two f eed pumps.These two oper ation modes ar e demonstrated in many aspec ts Analysis and this p aper gives the final c onclusion.
