【摘要】 以金沙江干流梯级水电站水库群为研究对象,建立了金沙江梯级水电站水库群兼顾保证出力要求的以发电量最大为目标的长期优化调度模型;考虑水电系统的调峰要求,建立了金沙江梯级发电量最大长期优化调度模型。均用逐次逼近动态规划法求解,结果表明,调峰系数不同对梯级水电站发电效益及运行方式有明显影响。更多还原

【Abstract】 With the cascade hydropower stations on the Jinshajiang River as a study object, a united long-term power generation operation and optimal operation model for the Jinshajiang cascade hydropower stations is established. Taking the peak regulation of hydropower systems into account, a long-term optimization model of the maximum peak regulation expectation for the Jinshajiang cascade hydropower stations is set up. The models are solved by the dynamic programming with successive approximation. The results show that different coefficients of peak regulation will obviously affect the generation benefit and operation mode of cascade hydropower stations.更多还原
