摘要
通过对二滩水电站水轮机在枯水期降低水库水位运行的可行性论证,并结合其中涉及到的水文、动能经济、水工建筑物等诸多影响因素的综合论证结论,提出了水轮机降低最小运行水头后的能量指标、空蚀特性和稳定运行范围以及应注意的问题,对已建、在建和前期的水电站机组运行和设计具有一定的参考意义。
It plays an important role to study on operation feasibility of Ertan Hydropower Station lowering its reservoir design dead level during low water period as a preliminary emergency scheme, in order to mitigate the power shortage and add adjustable volume of the reservoir, quantity of electric power and income. This paper gives the characteristics of energy ＆ cavitations of turbine, the area of steady operation and attentive matters based on studying on operation feasibility of turbine lowering reservoir water level during low water period, and combined with the analysis conclusion of hydrology, energy economy, hydraulic structure, etc, which could be used for reference for the operation ＆ design of generating units of hydropower station.
