摘　　要：针对山西兴能发电有限责任公司古交电厂3号、4号机组在试运行期间,给水泵在某一个工作区间存在非线性特性,导致给水流量频繁摆动的问题,提出了几种解决方法,并通过对液力耦合器工作原理的研究,分析了通过调节控制油压力改变耦合器工作区域的原理,并通过此方法最终解决给水流量的摆动问题,这种方法对出现此类问题的其他电厂有一定的参考作用。Due to the nonlinear feature of feed water pump in a certain working area, the problem of unstable feed-water flow happened in Shanxi Xingneng Gujiao Power Plant and some methods are tried to figure such problem. The working principle of the hydraulic coupler is studied and it is concluded that by adjusting the oil pressure to change the working area of hydraulic coupler, the problem of unstable feed-water flow can be addressed, which is of significance for other power plants to refer to.
