Cascade pump station forebay water level control method and system based on interstage feedback
The invention provides a cascade pump station forebay water level control method and system based on interstage feedback. The method comprises the steps that the current water level and the safe water level of a forebay of each stage of pump station and the current output flow of each stage of pump station are obtained; calculating the error between the safe water level of the forebay of each pump station and the current water level; the flow of the next-stage pump station is fed back to the previous-stage pump station; the previous-stage pump station calculates the output flow of the previous-stage pump station according to the feedback flow of the next-stage pump station and the error between the safe water level of the next-stage pump station and the current water level; calculating the output flow of each stage of pump station, and controlling the water level of the forebay of each stage of pump station to a safe water level. According to the scheme, a combined control logic method is provided according to the multi-stage linkage relation of the pump stations, the flow of each stage of pump station is synchronously controlled, and then the height of the water level of each stage of forebay is synchronously adjusted to the safe water level.
本发明提出一种基于级间反馈的梯级泵站前池水位控制方法和系统。其中，方法包括：获取各级泵站的前池的当前水位、安全水位和各级泵站的当前输出流量；计算各级泵站的前池的安全水位与当前水位的误差；将后一级泵站的流量向前一级泵站反馈；所述前一级泵站根据反馈的后一级泵站的流量和后一级泵站的安全水位与当前水位的误差，计算所述前一级泵站的输出流量；计算各级泵站的输出流量，控制各级泵站的前池的水位至安全水位。本发明提出的方案，根据泵站的多级联动关系，提出了联合控制逻辑方法，对各级泵站的流量进行同步控制，进而同步调节各级前池水位的高度至安全水位。
