Controlling Varying Rate of Upstream Water Level of Mawan Sluice for Increasing Power Output

马湾拦河闸水利枢纽利用闸前水位～库容关系曲线和闸门开度-水位-泄量关系表作出水位变率-闸门开度变量关系表,根据水位变率实现了高水位发电.

The key for increasing power output of Mawan multipurpose sluice is to keep its upstream water level as high as possible constantly. Based on the upstream water level-reservoir storage relation curve and the sluice opening-upstream water lever-sluice discharge relationship, the varying rate of upstream water level-sluice opening variation curve is drawn out. According to this relation curve, the sluice discharge could be controlled to increase power output of the power units in the sluice as was expected.
