On Monitoring and Testing System of the Hydropower Unit Vibration Based on Virtual Instrument Technology

In this paper, the advantage of virtual instrument technology is analyzed, and vibration-monitoring system of hydropower unit based on virtual instrument technology was developed combining the requirement of vibration monitoring. The design idea on hardware configuration and functions of each software system module of the system are introduced. The test experiments are made in the laboratory. Experiment results show that the system developed in this paper can realize the function of real-time sampling of the data, monitoring, analyzing, testing and remote diagnosis of the hydraulic vibration.
