| Abstract: | On the basis of analyzing the running characteristics of doubly-fed generator(DFIG)and the AC excitation source back-to-back voltage-fed frequency converter controlled by pulse width modulation(PWM),the control strategy for electrical control parts of variable-speed constant-frequency(VSCF)based on rotating coordinate system of stator magnetic field was proposed.Simulation model of VSCF was built by MATLAB.The simulation of the interconnected operating characteristics of VSCF under the proposed control strategy was conducted.Simulation results showed that the proposed control strategy is reasonable and the designed controller is effective. |
