[0020] The present invention will be described in further detail below with reference to the accompanying drawings.
[0021] like figure 1 shown, figure 1 The system structure diagram of the present invention, the wind power converter includes grid-side converter GSC, machine-side converter LSC, DC bus voltage bleeder circuit DBR, DC bus voltage bleeder circuit DBR includes IGBT, DC load bleeder resistor R, The diode is connected in series with the DC bleeder resistor R after the diode is inversely connected to the IGBT.
[0022] The grid voltage of the wind turbine is monitored in real time. When the detected grid voltage is a set multiple of the rated voltage, here is an example of 1.1 times. When the detected grid voltage is 1.1 times the rated voltage, the converter enters the high-voltage ride-through control state, and the grid-side converter increases the reactive output by changing the reactive current. The reactive current calculation formula is I q =k*(M Ug -1), ...
