调度函数作为一种能够明确指导水电站水库运行的技术,较常规的水库调度图能更有效地发挥水电站的运行效益。针对调度函数的编制特点及其存在的优化空间,将蚁群算法应用于水电站调度函数的优化模型中。以金沙江中游梯级水电站群为实例,针对其初始调度函数进行优化,并模拟其长系列径流的发电调度过程。计算结果表明,经过优化后的调度函数能显著提高水电站水库的运行效益,有效指导水电站水库的实际调度运行,体现了模型的实用性。
Dispatch function, as a technique that can clearly guide the operation of hydropower station reservoirs, can make the hydropower station run more effectively than the conventional reservoir dispatch map. According to the characteristics of the scheduling function and its existing optimization space, the ant colony algorithm is applied to the optimization model of hydropower station scheduling function. Taking the cascade hydropower station in the middle reaches of the Jinsha River as an example, the initial scheduling function is optimized and the long-runoff schedule is simulated. The calculation results show that the optimized scheduling function can significantly improve the operating efficiency of the reservoir and effectively guide the actual operation of the hydropower station reservoir, which shows the practicability of the model.
