Active Disturbance Rejection Control Strategy for Permanent Magnet Synchronous Wind Power System

With the development of renewable energy power system, the installed capacity of fan in the power grid is increasing day by day. Wind power is widely used because it cancels the gearbox, so it can realize the uninterrupted operation of the faulty unit. However, grid side voltage failure often occurs. So, it is very important to study the transient characteristics and control strategy of fan voltage crossing. In this paper, the dual PWM is studied, and the related model of fan system is established. Adaptive LADRC is proposed to improve the stability of the system. Finally, the simulation platform of wind power grid connection was built by Simulink software, and the voltage fault condition of power grid was set up. The traditional control method was compared with the proposed control method, and the effectiveness of the proposed method was verified.
