摘要

运用MATLAB采用遗传算法对水电站厂内机组负荷分配情况进行模拟计算，在发电量满足调度要求并保证安全优质的情况下对机组负荷分配进行调整，优化机组运行使电站的耗流量减少；并对计算数据进行分析，研究峰谷负荷差对耗流量的影响。结果显示，峰谷负荷差对电站耗流量的影响可以做出定量的分析，该结论对于制定峰谷时差电价有一定指导意义，对于安排水电站优化运行，提高水电站运行效率有十分重要的现实意义。%The unit load allocation of Manwan Hydropower Station is simulated by using MATLAB based on genetic algorithm. The model can adjust unit load distribution and optimize unit operation under the premise of consuming less water quantity, meeting scheduling requirements and ensuring safe and high-quality power generation. The calculation data are also analyzed to study the influence of difference between peak and valley load on water consumption. The result shows that the influence of difference between peak and valley load on water consumption can be quantitatively calculated. The conclusion has an important practical significance for the development of peak pricing and the improvement of generation efficiency.
