Flow regulation method and system based on circulating water quantity control value

The invention provides a flow regulation method and system based on a circulating water volume control value, and the method comprises the steps: continuously measuring the condensed water flow of a condensed water outlet of a steam turbine in a measurement period, and the measurement period comprises a plurality of time periods with the same length; integral average calculation is conducted on the multiple condensate flows obtained through measurement in all the time periods in the measurement period, and the average value of the condensate flows is obtained; and multiplying the average value of the condensed water flow by a preset circulation rate to obtain a circulating water quantity control value. According to the invention, the difficulty and the cost of measuring the control value of the circulating water volume can be reduced, and a simple method is provided for controlling and regulating the flow of the circulating water. 本发明提供了一种基于循环水量控制值的流量调节方法及系统，所述方法包括：在一个测量周期内持续测量汽轮机凝结水出口的凝结水流量，所述测量周期包括多个长度相同的时段
