Control is in rated speed, so reducing the opening speed of shutter when the wind velocity increases, shutter is increased when wind speed reduces
Opening angle.
Another foundation of the opening speed of shutter is the fault level of wind power generating set.The failure of wind power generating set
There is the emergency shutdown of catastrophe failure including unit in grade：Catastrophe failure includes that rotating speed is too high, vibrates excessive etc.；Unit occurs one
As failure typically shut down, generic failure includes generator-temperature detection is high, and wind speed is beyond unit operation scope etc., and orderly closedown：
I.e. unit does not have faulty manual stoppage.The closing velocity of shutter is most fast during emergency shutdown, and shutter is closed during general shutdown
Speed is placed in the middle, and the speed that shutter is closed during orderly closedown is most slow.
Control system of wind turbines has uninterrupted power source, and shutter is also connected with uninterrupted power source, to ensure in power network
Unit can perform shutdown when power down.
The present invention is easy to implement, and can effectively play a protective role again, major advantage：
1) present invention use shutter brake modes be mainly by change into the wind speed size of unit come realize shutdown
, it is the absorption that energy is reduced from source, the load that unit needs to bear thus greatly reduces, improve wind-power electricity generation
The security performance of unit；
2) control system realizes the shutdown of unit by controlling the folding of multiple shutters, when any one shutter failure
When can start other shutters realize wind power generating set shut down, improve wind power generating set security performance；
3) control system according to the speed demand of wind power generating set and wind conditions, can control the folding angle of shutter
Degree and folding speed, so that the control of unit is more steady.
