摘  要：部分水电站由于没有安装闸门流量计或不具备安装条件，导致闸门弃水流量无法实现自动采集，只能采用人工估算方式，数据精度较差。本文介绍了某水电站在不具备流量计情况下，通过闸门监控系统实现流量计算的方法，详细介绍了过闸流量计算的基本数学模型、方案比选设计和实现方法。

Abstract: In some hydropower plants, it’s difficult to measure the water flow discharged though sluice gates ,because some devices ,such as flowmeters are not installed. The paper presents a scheme to calculate water flow in the SCADA system and introduces the specific implemen
