摘要
Abstract
In doubly fed induction generator of wind power system control technology ,flux information is the basis of effective torque control. A kind of novel method of observation rotor flux for doubly fed induction generator of wind power system was proposed. It was adopted in the new voltage model method that was compensated with feed forward. The problem such as DC bias and integral saturation caused by the pure integrator could be effectively solved. In this method,the estimated flux was used to compensate the phase lag caused by the inertia element. The pure integrator and improved flux estimator were compared according to simulation experiment. The simulation results show that improved flux estimator is a very good suppression of the drift caused by DC bias . The doubly fed induction generator of wind power system model and flux estimator were established according to method ,and the results show that the method mentioned above are effective and feasible.关键词
