[0012] See figure 1 As shown, on the basis of the standby state, start-up process, power generation process, and shutdown process of the traditional wind turbine control method, the present invention adds the control process of the wind turbine under strong wind conditions, which mainly includes the following AC three steps .
[0013] Step A. Monitor the status of the generator set, perform step B when the fan is running normally, and stop when the fan fails.
[0014] Step B. Monitoring wind speed: When the wind speed is greater than the maximum operating wind speed, for example, greater than 30m / s, then stop; when the wind speed is less than or equal to the cut-out wind speed, for example, less than or equal to 25m / s, then perform step A and return to normal operation ; Otherwise, go to step C. Among them, the maximum wind speed and cut-out wind speed are calculated according to the actual load of different wind turbines.
[0015] Step C. Adjust the blade angle through the pitch s...
