【摘要】：水电站短期优化调度对于水资源高效利用具有重要的作用,负荷过程变化频繁是制约优化调度成果实用性和增加水电站群系统优化求解难度的关键。以天生桥一级水电站为研究对象,基于峰荷、腰荷及基荷等3个特征负荷的水电站日典型负荷过程,引入基荷系数和调峰系数2个特征参数,推导了特征负荷与特征参数之间的数学关系,提出了水电站短期优化计划的快速制作方法。该方法实现了优化数学模型的高效降维,增强了优化成果的适用性和可操作性。实例应用表明该方法既可得到最优解、也可得到经济运行的负荷图范围。
[Abstract]:Short-term optimal operation of hydropower stations plays an important role in the efficient utilization of water resources. The frequent change of load process is the key to restrict the practicability of optimal dispatching results and increase the difficulty of optimal solution of hydropower station group. Taking Tianshengqiao Hydropower Station as the research object, based on peak load, In the typical load process of hydropower station with three characteristic loads such as waist load and base load, two characteristic parameters, the base load coefficient and peak load regulation coefficient, are introduced, and the mathematical relationship between the characteristic load and the characteristic parameters is deduced. This paper puts forward a fast method for making short-term optimization plan of hydropower station. The method realizes the efficient dimensionality reduction of optimization mathematical model and enhances the applicability and maneuverability of optimization results. The application of this method shows that the optimal solution can be obtained by this method. You can also get the scope of the load chart of economic operation.
