Research on the Direct Power Control Strategy of Three Phase Type PWM Rectifier
A Model Predictive Direct Power Control(MP-DPC) strategy is proposed for traditional Voltage Oriented Direct Power Control(VO-DPC) system with problems like unstable switch frequency and control delay.This strategy uses model predicative controller to take the place of power lag loop comparator to enhance the speed of control system.Meanwhile
the control strategy is integrated with Space Vector Pulse Modulation(SVPWM) to modulate and control voltage space vector with the average voltage vector as the basic vector of the whole control process
which simplifies the structure of DPC system and lowers the difficulty of design.In the end
Compare the simulation results with the traditional test results
it shows that the proposed method used in the simulation is feasible and the analysis results is effective.
