Abstract

In this paper

the vibration fault of rigid tower of wind turbine is diagnosed and treated. On the basis of dynamic model of the rigid tower of wind turbine

the conditions for judging the resonance of the rigid tower are determined

the reasons of the tower resonance caused by overshoot of rotating speed induced by gust are analyzed

and an optimization method for predicting the wind speed control is put forward

which takes the stable power output as the aim and rotor as a ‘anemometer'

on the basis of feedback control of rotation speed of the impeller. Moreover

this method is applied to analyze the vibration fault of a rigid tower of a 2 000 kW wind turbine

and the results show that

the combined control of impeller speed feedback and estimated wind speed can effectively reduce the overshoot of impeller speed caused by gust

avoid the resonance of rigid tower of the unit

and the effect is remarkable.
