Abstract
In order to reduce the impact of large scale wind turbine during low voltage ride through(LVRT),load reduction controller based on the linearized model was proposed for the operation region above rated wind speed. The control strategy consisted of two MISO(multi-input single-output)controllers,which could output the compensation of torque and collective pitch angle to achieve the loads reduction on drive train and tower during LVRT. The comparison of the strategies based on the linearized model and band pass filter was carried out at first,and then the control effect was verified through the nonlinear-model simulation. The results show that loads can be reduced obviously during LVRT based on the proposed strategy and the performance is better than the control based on band pass filter.关键词
