Abstract
A feedforward compensation based active disturbance rejection control(FC-ADRC)strategy is proposed to address the contradiction between compensating speed and compensating overshoot in the traditional proportional integral(PI)control for dynamic voltage restorer(DVR).By improving the compensation overshoot problem of traditional PI control through ADRC strategy,and introducing the voltage and current of LC filter as feedforward to compensate the DVR controller,the fast voltage compensation is achieved for user side voltage sag to ensure the safety and stability of user side voltage.The simulation experiment results show that the proposed strategy maintains the high dynamic responsiveness of the DVR device while ensuring its adaptability to uncertain disturbances.关键词
