引水式水电站生态下泄改造对机组发电运行的影响

Impact of Ecological Discharge Renovation of Diversion Type Hydropower Stations on the Operation of Unit Power Generation

牛头山水电站于2020年完成生态下泄设施改造。电站在近年的发电运行过程中,发现生态下泄导致的电量损失超过设计值、机组运行特性有所劣化、生态下泄设备可靠性不足等问题,为此,提出通过减少下泄流量核定值、新建生态机组、优化机组运行方式、提高设备可靠性等方案,以降低生态下泄对电站发电运行的不利影响。

The Niutoushan Hydropower Station completed the renovation of its ecological drainage facilities in 2020.In recent years,during the operation of power plants,it has been found that ecological leakage leads to energy loss exceeding the design value,deterioration of unit operating characteristics,and insufficient reliability of ecological leakage equipment.Therefore,it is proposed to reduce the rated value of leakage flow,build new ecological units,optimize unit operation mode,and improve equipment reliability to reduce the adverse impact of ecological leakage on power plant operation.
