摘　　要：本文根据两段式水位调节系统的特点,分析了耦合作用产生的原因。在引进机组调试过程中,通过对试验性改造方案的运行考验,提出了两段式给水调节系统理想工作模式,最终达到充分利用WETR泵调速功能的目的。This paper makes an analysis on the causes of coupling effect in a two-sectional drum water level control system. A modified control strategy of the drum level control was put into a test run during the commissioning of an imported unit. Based on the testing result,an ideal operational mode of the two-sectional drum water level control system,which makes full use of the speed governing feature of Weir pump,was then proposed.
