Abstract

The invention provides a synchronous detection method and device for vibration data and working condition data of a wind generating set. The detection method comprises the steps of acquiring vibrationdata of a wind generating set and current signals on a stator winding in a first set period which are collected synchronously and acquiring working condition data of the wind generating set in a second set period, wherein the working condition data include the instantaneous rotating speed of the wind generating set and the first set period is included in the second set period; dividing the firstset period and the second set period according to a set time step, calculating a first rotating speed of each period obtained after division according to current signals of each period, calculating the effective value of the rotating speed of each period obtained after division according to the instantaneous rotating speed of each period, and determining an initial moment of working condition datasynchronous with the vibration data in the second set period. The method and the device can achieve synchronous detection of vibration data and working condition data of a wind generating set.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a method and device for synchronously detecting vibration data and working condition data of a wind power generating set. Background technique [0002] Wind energy is a pollution-free energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation. With the continuous development of new energy sources, the equipment requirements for wind power generators are also constantly increasing. [0003] The wind turbine will be subject to external vibration and vibration between components, which will cause vibration failure of the generator in the generator set. Vibration fault is the fault with the highest sudden frequency when the wind turbine is running. In order to ensure the normal operation of wind turbines and the safety of work...
