盐锅峡水电厂水轮机流量在线监测

On-line monitoring of turbine discharge of Yanguoxia Hydropower Plant

介绍了水轮机、水泵和大管道流量监测方法和盐锅峡水电厂机组流量在线监测系统 ,并得出如下结论 :①差压法是水轮机、水泵和大管道流量监测方法中费用最低 ,安装调试和运行维护最简便 ,适用于各种机型和条件的方法 ;②微机型监测装置自动化水平高 ,功能齐全 。

A discharge monitoring method for hydraulic turbines, pumps, large penstocks and an on_line monitoring system of unit discharge of Yanguoxia Hydropower Plant are described. Some conclusions are drawn as follows:①for discharge monitoring of hydraulic turbines, pumps and large_sized penstocks, the differential pressure method is not only lower in cost, but also convenient in installation, debugging, operation and maintenance;and it is suitable for different type of hydraulic turbines and different conditions;②the discharge monitoring device based on microcomputer is of higher automation level, complete functions and advanced technology.
