本文首先在滿足調节期內系统負荷要求以及充分利用水能资源的前提下,按系統煤耗量最小准則利用变分学原理推导出动力系统中水电站长期最优运行条件式。然后应用所建議的方法进行实例驗算;同时,提出了处理水电站容量限制的方法。验算結果表明:本文所建議的方法此“单位节省法”和“水电站发电量最大”的方法能取得更大的系統煤耗节省值。

In this paper, under the premise of meeting the system load requirements during the regulation period and making full use of hydropower resources, this paper derives the long-term optimal operating conditions for hydropower stations in power systems based on the principle of variational principles according to the minimum system coal consumption criterion. Then, the proposed method is applied to verify the case. At the same time, a method to deal with the capacity limitation of hydropower station is proposed. The verification results show that the proposed method of this paper can achieve greater system coal consumption savings by using the “unit saving method” and the “hydropower generating capacity maximum” method.
