建立了以抑咸为目标的珠江流域梯级水库群优化调度模型，采用优化算法对调度方案进行寻优。通过珠江流域典型枯水期实测资料进行模拟计算，将优化计算结果与实际调度结果进行对比分析，优化调度模型在提高补水量的发电效率、缓解电量损失方面具有优势，可为珠江枯水期水量统一调度方案的制定提供借鉴。%As the goal of saltwater tide control, cascade reservoir optimal operation model in Pearl River is established, and optimal algorithm is adopted to search the best scheme.Using simulation calculation in the typical drying season in Pearl River, the contras-tive analysis of optimal result and the real operation scheme shows that, the optimal operation model has obvious advantage in raising power generation efficiency with supplementary water and decreasing electricity loss.The model provided reference for the unified regulation of dry season in the Pearl River.
