Research And Development Of Wind Turbine Condition Monitoring Device

With the rapid development of wind power technology, how to reduce the economic losses caused by the frequent failure unit has become an issue of most concern, some of the traditional means of testing and maintenance has been difficult to meet the requirements, so the condition monitoring methods to be applied gradually in wind turbines detection on.This paper, based on the actual operation of the wind farm design a device for monitoring the state of the wind turbines, including the overall structure of the entire device design, circuit design related hardware as well as software programming. The device is mainly selected vibration signal and the output of the generator voltage and current signals live signal transmission unit as the object, and then use a digital signal processor (Digitial Signal Processor, DSP) as the core of independent research and development of intelligent data processor, Simultaneous sampling on site to complete the required signal, network transmission signal processing and signal. Finally, the corresponding communication network to transmit signals to the host computer, complete the related signals for further processing and analysis to determine the operating conditions of the unit. The state monitoring device has been used in a wind farm, stable operation for a long time, during which successfully predicted a gear box failure to verify the reliability and stability of this set of devices.
