Wind Turbine On-Line Monitoring System Based on Vibration Mechanics

Abstract:

Wind turbine in the run-time under natural wind conditions, it will cause the turbine vibration. The vibration will cause the body of material fatigue, will increase the probability of the unit appears damaged, and will cause the turbine speed dropped significantly reduce the output power. This paper introduced a wind turbine monitoring system based on vibration Mechanics, which included the hardware test platform, remote transmission and monitoring software platform based on LabVIEW. Hardware monitoring used the computer as the control centre, according to the operating parameters of wind power generation system which included the wind speed, the generator voltage and current, the charging voltage, current and power, the vibration quantity of the wind turbine, the working state of the energy storage devices and the load, displayed and stored the data and curve through the sensors and signal conditioning circuit. Senseless monitoring was used to monitor the speed of generator. This monitoring system provided the basis for the match of the engine power and efficiency of wind turbine and generator.
