Simulation Research of Three-phase VSR Based on A Feed-forward Control strategy in Stationary Coordinate System

To improve the anti-interference ability of three phase voltage source PWM rectifier and overcome the shortcomings of complex control structure and difficult tuning of control parameters in dq coordinate system, a feed-forward control strategy based on αβ coordinate system is proposed: because of the application of predictive current principle and the design of control system in static coordinate system, the difficulty of design is reduced, and by adopting anti-interference feed forward control technology, the problem that three-phase VSR is greatly affected by input voltage fluctuation and output current variation of power grid has been solved. The system simulation model is built, and the effectiveness of the control strategy is verified.
