英文摘要 | The invention relates to a wind driven generator torque control method for passing through a resonance band quickly. The method comprises the steps of setting a resonance region according to a generator speed value corresponding to a resonance frequency of a tower and bandwidth of the resonance band, setting different generator torques according to the current generator speed value and a wind speed value, and allowing the generator speed value to pass through a region between a low-speed region and a high-speed region quickly. The control method comprises the steps of a first-order filtering algorithm of generator speed, torque increasing value calculation of the low-speed region, torque increasing value calculation of the high-speed region, judgment and switching of six different running states of a fan. The control method has the characteristics of reducing the load of the fan, effectively improving the safety of the fan and prolonging the service life of the fan; the power grid fluctuation due to frequent switching of the fan near a resonance point is avoided; and the power quality can be improved effectively. |
