摘　　要：以乌江流域12个梯级电站为例,构建了流域梯级发电量最大模型,采用逐步优化算法(POA)和离散微分动态规划(DDDP)的混合型算法对模型进行求解,全面考虑乌江流域季调节及以上电站对整个流域中的效益情况,采用相同的数学模型和径流资料,在有无电站两种情况下研究了乌江流域梯级各调节电站对全系统的效益贡献。结果表明,梯级电站效益贡献的比例与各电站本身的调节库容和调节能力成一定的正比关系,龙头电站对整个流域梯级的贡献十分显著,但单纯将流域梯级总效益的提高归功于龙头电站的贡献并不准确,下游较大调节能力电站的效益贡献亦不可忽略。Taking 12 hydropower stations in Wujiang River Basin as an example,the maximum cascade generation model was established.The hybrid progressive optimization algorithm（POA）and discrete differential dynamic programming（DDDP）algorithm was used to solve the model.Taking fully into account of the benefits of season regulation and above power station in Wujiang River Basin,the same mathematical model and runoff data were adopted to analyze the benefit contribution of cascade regulated power to the whole system.The results show that the benefit contribution rate of cascaded hydropower stations is direct proportion to the regulation reservoir storage and capacity of power station itself;leading power station in the river basin plays an important role,but only attribution of improving benefit of cascade basin to the leading power plant is inaccurate,the benefit contribution of the downstream greater regulation ability of power plant can not be ignored.
