Cascade hydropower station minimum discharge flow dynamic control method and system
The invention belongs to the technical field of hydropower station control, and particularly relates to a cascade hydropower station minimum discharge flow dynamic control method and system. The method comprises the following steps of 1, judging whether the original minimum discharge flow of a water reducing river reach between cascade power stations meets an optimal value interval or not; 2, monitoring and analyzing backwater of reservoir areas of different dam water levels of a reservoir, and determining corresponding incomplete connection river reach lengths of different water levels and control section flow or water levels of the river reach; 3, acquiring connection data and water resource utilization data of the water reducing river reach, and evaluating the control of the current minimum discharge flow according to the acquired data; and 4, re-determining the control section of the minimum discharge flow scheduling. On the basis of optimizing the control method, a more accurate and convenient minimum discharge flow monitoring mode of the hydropower station is provided through the change of control conditions, and the water energy utilization efficiency of the cascade power station is improved on the premise of ensuring the ecological environment of a river in real time.
本发明属于水电站控制技术领域，具体涉及一种梯级水电站最小下泄流量动态控制方法及系统。所述方法执行以下步骤：步骤1：判断梯级电站间减水河段的原最小下泄流量是否满足最优值区间；步骤2：进行水库不同坝上水位库区回水监测分析，确定不同水位级相应的不完全衔接河段长，以及河段的控制断面流量或水位；步骤3：获取减水河段的衔接数据及水资源利用数据，根据获取的数据对当前最小下泄流量的控制进行评价；步骤4：重新确定最小下泄流量调度的控制断面。在优化控制方法的基础上，通过控制条件的变化，提出更为准确和便利的水电站最小下泄流量监控方式，在实时保障河流生态环境的前提下提升了梯级电站的水能利用效率。
