影响构皮滩水电站发电效益若干因素分析

构皮滩水电站是乌江流域水电开发中规模最大的骨干工程,为正确分析构皮滩水电站投产后的发电效益,针对工程建设工期较长,且在建设过程中设计条件有所变化的具体情况,对可能影响电站发电效益发挥的因素进行了分析。结果表明,由于构皮滩水电站调节性能较好,仅电站入库径流变化(含河道外用水的增加)和下游思林水电站顶托两个因素对构皮滩水电站发电指标影响较大。分析结果可以指导电站在运行期发电计划的拟定和上网电价的核定。

Analysis of influential factors of generation benefit of Goupitan Hydropower Station

Goupitan Hydropower Station is the largest key projects in hydropower development of Wujiang River.Aiming at its long construction period and the fact that the design conditions change in the process,in order to analyze generation benefit after commissioning of Goupitan Hydropower Station,we study possible influential factors of generation benefit.The results show that the regulation of Goupitan Hydropower Station is satisfying,therefore,only the change of inflow runoff(including increase of water consumpti...
