云南省水电集群出力特性

目前云南省电力供需形势分析时,仅将全省单个电站或流域的出力特性简单叠加作为全省水电出力特性,未将全省水电作为一个整体深入研究,忽略了不同河流水文的差异。为此,统计了云南省六大水系上多座水电站近54年的来水情况,分析了流域内和流域间的来水补偿特性,提出了基于年均发电量的全省水电集群方法,并以实例验证了集群后全省水电出力曲线与单电站出力曲线简单叠加的区别。

Output Characteristics of Hydropower Cluster in Yunnan Province

When analyzing the energy demand and supply in Yunnan Province at present, the output characteristic of hydropower is simply superimposed by the output characteristic of a single hydropower station, and the hydropower is not studied as a whole as. At the same time hydrological differences of different rivers are ignored. Therefor, this paper made a statistics of inflow in near 54 years for many hydropower stations in six basins in Yunnan Province, and the compensation characteristic of inflow between basins were analyzed. The method of hydropower cluster base annual generating capacity was proposed. Finally, the output characteristic of hydropower cluster and the difference of simple superimposition for single hydropower station were verified by example.
