沅水上游水电站投运后对发电效益影响分析
|
摘要
为分析沅水上游水电站投运后,对五强溪水电站发电效益的影响,首先根据流域实际来水还原计算五强溪的天然来水过程,利用还原计算的天然来水,按五强溪实际运行控制水位计算发电量,五强溪实际年均发电量比还原计算年均发电量增加3.297亿k W·h。通过梯级水库的调节、补偿作用,可显著增加五强溪及梯级水电站的发电效益。
In order to analyze the impact of the operation of Yuan River upstream cascade hydropower stationon the power generation benefit of the Wuqiangxi Hydropower Station,firstly,the natural incoming water process of Wuqiangxi Reservoir is calculated according to the actual water inflow process of the river basin. Using the calculated natural incoming water,the generated energy of Wuqiangxi Reservoir controlled by the actual operating water level is calculated. The calculated average annual generated energy is 329.7 million k W·h less than the actual generated energy.The power generation benefits of Wuqiangxi Hydropower Station and cascade hydropower stations can be significantly increased through the regulation and compensation of cascade reservoirs.
