摘要:
水库调度图作为指导水电站安全高效运行的依据，一直是水库调度研究的热点，然而现有研究大多以单库调度图为对象进行优化，或是基于中长期发电优化调度模型绘制梯级水库调度图。单库优化调度图较难满足梯级调度要求，而后者虽然理论成熟、应用广泛，但存在建模、求解复杂，步骤繁琐，误差较大等的缺点。鉴此，本文提出了一种采用模拟与优化相结合的技术绘制梯级水库优化调度图的实用方法。该法通过直接优化梯级水库常规调度图的调度线，从而获得优化调度图。以乌江流域4座调节性能较好的水库构成的梯级水库为研究对象进行实例分析，模拟调度结果表明较大地提高了梯级长期发电效益，验证了该法的可靠性和有效性，从而为梯级水库优化调度图的绘制提供了新思路。
Reservoir operation chart has been a hot topic of the reservoir operation study as a basis for the guidance of the efficient and safe operation of the hydropower station. However, existing studies are mostly studying on the optimizing drawing of single reservoir, or research on the drawing of cascade reservoirs operation chart using a long-term power optimization scheduling model. Single reservoir optimized operation chart is hard to meet the cascade scheduling requirements, while the latter theory is mature, widely used, but has its flaws. For this, this paper puts forward a drawing way of cascade reservoirs optimal operation charts, using the combination technology of simulation and optimization, through the direct optimization of the cascade reservoirs conventional operation curves. For the cascade hydropower stations on the WujiangRiver, simulation scheduling results show considerably increase on the cascade long-term generation benefit. Thus verify the reliability and validity of the method, so as to provide a new idea to draw the cascade reservoirs operation chart.
