2、运行实时监测系统，该系统实现了水轮机工的作水头、流量、出力等参数的 实时在线监测、显示、处理以及存储，使工作人员随时了解水轮机的运行状况， 为建立水力机组优化运行系统打下基础。 实现水力机组的高效稳定运行及优化运 行均具有一定的实际指导意义。 关键词关键词：水力机组 虚拟仪器 监测系统 Abstract Hydroelectricity is regarded as green energy of mainly development in our country.It has many characteristics such as quick start-up, low operation
3、 outlay and low pollution. How to make full use of hydro-electric power will enormously promotes the development of our countrys economic. Therefore, to test, analyze and optimize the hydraulic parameters effectively will play an important role in the efficient and reliable operation of hydro-genera
4、ting units. A real-time monitoring system of operation of hydro-generating units based on virtual instrument techniques was designed in this paper by using LabVIEW programming method.With the system,the real-time monitor,display,data processing and storage of turbine operating parameters such as water level,water flux and the output are achieved.The hydraulic efficiency can be calculated and displayed real-timely according
