摘　　要：水电站厂内负荷优化分配是实时经济运行的核心内容,其结果表达方式反映了水电站机组间负荷分配规律。现行对负荷分配的研究多集中在算法上,更注重负荷分配过程,很少涉及对分配结果表达方式的研究。以耗流量最小为目标,建立了负荷优化分配模型,利用动态规划法进行求解,得水电站机组间的最优动力特性曲线,提出负荷最优分配规则图的概念并对其绘制方法和应用做了详细介绍,该图使水电站短期优化调度和实时经济运行更加简便快捷。Optimal load allocation rule in hydropower stations is the core content of real-time, economic operation, whose expression of results reflects the rules of optimal load allocation of generators in hydropower stations. The present study of load allocation is concentrated more on the algorithm and pays more attention to the process of the load allocation, rarely involving the results expression. Based on making the flow consumption minimum, an optimal load distribution model was established and solved using dynamic pro- gramming method, achieving the optimal power characteristic curve of generators of hydropower stations. The concept, figures of optimal load allocation rule, was proposed, and the method to draw it was described in detail. The figure is of great operability and practicality value to enhance short-term hydropower optimal scheduling and real-time economic operation in hydropower station.
