| Abstract: | The permanent magnet synchronous direct-drive wind power generation system with dual PWM control AC-DC-AC voltage source converter used as the grid-connected main circuit was proposed.The control theory of the system was analyzed and the control model of the back-to-back PWM converter was established.An experiment platform of permanent magnet synchronous direct-drive wind generation system based on the back-to-back PWM converter was established by us-ing high-speed DSP TMS320F2812 and the control strategy of the system was validated through the experiment.The vari-able-speed constant-frequency operation is realized and the output active power and reactive power can be independently regulated.The system has excellent dynamic and static performance. |
