Abstract:
# D! P2 `5 J8 d# e: V* X3 U! vThis paper proposed an AC-DC-AC indirect converter used in distribute wind power generate system has simple construction and high reliability, compared to AC-excited VSCF (variable-speed constant-frequency) wind power generation system. PWM rectifier and inverter are adopted in the system to realize power converter. PWM rectifier adopted triangle carried direct current control to realize input current follow the input voltage, and make sure current low THD and high input PF. SPWM control mode is adopted in inverter control, make sure the inverter have good output waveforms and dynamic performance.
