| description | The invention relates to a wind power generation system, in particular to a pure square wave permanent magnet wind collection type wind power generation system which comprises a pure square wave permanent magnet generator and back-to-back double PWM converters. The system operation mode comprises that a motor stator winding passes through a four-quadrant converter and power grid energy bidirectional flow, a machine-side converter controls the rotating speed and power of a permanent magnet generator, a network-side converter performs voltage stabilization control on a direct-current bus and controls a network-side power factor, and the modulation mode is a controller with the rectification step-up ratio being more than 10 times. Paddles of the generator wind turbine are connected with the flange plate to form an impeller which is placed in the wind collecting cover. According to the utility model, the step-up ratio of more than 10 times is realized, the power generation efficiency of the system exceeds 0.63, t |
