Integrated control method and system for flood discharge gate of hydropower station
The invention discloses an integrated control method and system for a flood discharge gate of a hydropower station. The method comprises the following steps: calculating the output flow of a gate dam and the change of the storage capacity in unit time by adopting a binary interpolation method; calculating the input increment flow per unit time; calculating the discharge output flow of the gate dam; calculating the unit efficiency and the output flow of unit power generation by adopting an interpolation method; determining the current actual input flow; and calculating the opening degree of the gate, sending the opening degree to the gate control module, and automatically adjusting the opening degree of the gate. According to the invention, labor intensity is reduced, manpower is saved, and reservoir scheduling procedures are simplified; the calculation intervals are dense, and accurate control over the reservoir area water level can be achieved; seamless integration of all the systems is achieved, and project construction cost is saved.
本发明公开了一种水电站泄洪闸门集成控制方法及系统，该方法包括步骤：采用二插值法计算闸坝出库流量、单位时间内库容的变化；计算单位时间入库增量流量；计算出闸坝泄流出库流量；采用插值法计算出机组效率、出机组发电出库流量；确定当前实际的入库流量；计算闸门开度并将开度值发送至闸门控制模块，自动调节闸门开度。本发明降低了劳动强度，节省人力，简化水库调度程序；计算间隔密集，能实现库区水位的精准控制；实现了各系统的无缝集成，节省项目建设费用。
