某水电站轴流转桨式水轮机协联曲线的优化

Optimization of Coconnection Curve of Shaft-Rotating Propeller Turbine for a Hydropower Station

本文对某水电站在不同水头下对1号机组进行非协联状态下的调整试验,利用指数效率试验法和固定导叶工况试验法,综合获取机组最优协联关系,并在2号机组和3号机组进行结果验证,最终优化出3台机组的最优协联曲线,指导机组经济平稳运行。

In this paper, the adjustment test of unit 1 of a hydropower station is carried out under the condi-tion of non-coconnection. By changing the water head, the optimal coassociation was obtained by using the exponential efficiency test method and the fixed guide vane test method. After the veri-fication of unit 2 and unit 3, the optimal coassociation curve is finally optimized. It guides the unit economy to run smoothly.
