【摘要】 针对三峡梯级电站峰、谷、平典型负荷特征,建立梯级电站同(异)步式调峰和联合调峰模型。模型中考虑上下游电站间水头联系,计及水头损失,增强了调度模型的实用性和合理性。基于逐次逼近算法求解梯级调峰模型,给出了计算步骤。结合算例比较分析调峰模型,得出联合调峰能提高梯级总效益,以及增大调峰幅度不一定减少发电量等结论。更多还原

【Abstract】 Coupled with the characteristics of typical load,this paper establishes the synchronous(asynchronous) and coordinative peak modulation optimal models of cascade hydropower stations.Head loss and relation are included in the models,which greatly improves utility and reasonability of these models.Successive approximation method is directed to solve the peak modulation problems.Finally,A case study is served for demonstrating relative analyses between models and some utility rules is induced.更多还原
