How to make full use of hydro-electric power will enormously promotes the development of our country’s economic. Therefore, to test, analyze and optimize the hydraulic parameters effectively will play an important role in the efficient and reliable operation of hydro-generating 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 to the real-time monitoring data of hydro-generating units,so that the operators can hold the running status of turbine at any time,the realization of efficient and stable operation and optimal operation of hydro-generating units.Keywords: Hydro-generating Uni...
