介绍了一种水轮机效率在线监测分析系统,采用超声波流量计测量水轮发电机组特定工况下的流量,结合水轮发电机组运行方式,检测出水轮发电机组的效率,在此基础上结合计算机人机界面、SQL 数据库以及技术统计方法构划出不同水头、不同出力时的水轮发电机组效率曲线。
An on-line monitoring and analysis system for turbine efficiency is introduced. The ultrasonic flowmeter is used to measure the flow rate under the specific conditions of hydro-generator set. Combined with the operation mode of hydro-generator sets, the efficiency of hydro-generator set is detected. Based on this, Human-machine interface, SQL database and technical statistical methods to construct a different head, different output efficiency of the turbine generator curve.
