摘　　要：国产引进型３００ＭＷ机组旁路阀门及控制系统价格昂贵。铜陵电厂３号机组改进旁路系统的设计，采用电动单速旁路阀门，ＢＰＣ的ＤＰＵ控制组态在ＤＣＳ的工程师站上实现，在操作员站上操作，并设置必要的控制保护。１年多来的运行情况表明，它是一种较为实用可靠、投资少的设计方案。The bypass valves and their control system in the domestic 300 MW units ~produced by imported technology are very expensive. The design to improve the bypass system of No.3 unit in Tongling power plant adopts electric single - speed by- pass valves, the DPU control status of BPC is realized on the engineer station of DCS. The operation is on the operator station of DCS equipped with necessary control protection. The operation for more than a year indicates that it is a relatively practical, reli- able design option with less investment.
