Reforwarding row；If mean wind speed is greater than 25m/s, blower reduces given power and continues to run.
It preferably, is more than 25m/s when measuring mean wind speed, giving power with the rate of the fixation of 50KW/S reduces power,
Finally run with the low-power of 500KW in this wind speed interval.
Preferably, this patent current practice is in 1.5MW type, from 0~rated power, the specified function of 1.5MW unit
Rate is 1540KW
Preferably, after measuring mean wind speed and being more than 25m/s, giving power with fixed rate reduces power, this is fixed
Speed be 50KW/S.
Preferably, when wind speed maintains 25m/s~30m/s, blower low power run, for the low-power, specific model
It encloses for 500KW.
Preferably, if mean wind speed is less than 24m/s, given power with fixed rate start to increase to power output to
Determine power, which is 50KW/S.
Preferably, when instantaneous wind speed reaches 33m/s, blower protection is shut down；
Technical solution provided in an embodiment of the present invention has the benefit that according to air rate adjustment power of fan, specifically
Ground, after measuring mean wind speed and being more than 25m/s, giving power with fixed rate reduces Power operation；When wind speed maintains
When 25m/s~30m/s, blower is with low power run；When mean wind speed is greater than 30m/s, blower protection is shut down；Work as mean wind speed
When less than 24m/s, given power starts to increase to the given power of power output with fixed rate, can be transported with low-power load
Capable state continues to generate electricity, to reach the generated energy for promoting unit, increases the purpose of profit from power plant.Relative at present various million
The method that watt grade blower improves generated energy carries out secondary development on the basis of existing control algolithm, and new control algolithm is without increasing
Add any additional hardware device, saved cost, maximizing utilizes wind energy resources, promotes profit from power plant, while to unit
Service life, load, safety etc. substantially without influence, tool has been widely used and vast market prospect.

Concrete condition understands concrete meaning of the above-mentioned term in the invention.
Further detailed description is done to the present invention combined with specific embodiments below, but embodiments of the present invention are not limited to
This.
As depicted in figs. 1 and 2, the control method of the raising Wind turbines strong wind generated energy of the present embodiment, blower is according to function
Rate management gives output valve operation, and type is generally 1.5MW type.Specifically, it after measuring mean wind speed and being more than 25m/s, gives
Determining power reduces Power operation with fixed rate；When wind speed maintains 25m/s~30m/s, blower is with low power run；When
When mean wind speed is greater than 30m/s, blower protection is shut down；When mean wind speed is less than 24m/s, given power is opened with fixed rate
Beginning increases to power output and gives power.
The control method of the raising Wind turbines strong wind generated energy of the present embodiment, in incision wind speed to the section of cut-out wind speed
It is interior, under the premise of fully considering safety, strong wind is improved within the scope of blower allowable load and cuts out speed, unit is in new control
Under algorithm and cut-out wind speed processed, it can continue to generate electricity with the state of low-power load operation, to reach the power generation for promoting unit
Amount, increases the purpose of profit from power plant.Relative to the method that various Megawatt fans improve generated energy at present, the present invention is in existing control
Secondary development is carried out on the basis of algorithm processed, new control algolithm is not necessarily to increase any additional hardware device, has saved cost, can be most
That changes greatly utilizes wind energy resources, promotes profit from power plant, while on the service life of unit, load, safety etc. substantially without influence,
Tool has been widely used and vast market prospect.
As a kind of preferred embodiment, after instantaneous wind speed reaches 28m/s, because wind speed is can to fluctuate cracking, institute
With there will be two kinds of situations:
First is that mean wind speed does not reach 25m/s, blower can continue to run at this time according to given power；
Second is that mean wind speed has actually reached 25m/s, logic judgment is passed through in blower master control, can reduce given power after
Reforwarding row.
It should be understood that 28m/s represents instantaneous wind speed, what is represented is mean wind speed of the period as 3s, 25m/s representative
Mean wind speed, what is represented is that the period as the mean wind speed of 60s actually will appear both the above situation due to the fluctuation of wind.
As a kind of preferred embodiment, when instantaneous wind speed reaches 33m/s, blower protection is shut down.
It is more than 25m/s when measuring mean wind speed as a kind of preferred embodiment, gives power with the speed of the fixation of 50KW/S
Rate reduces power, is finally run with the low-power of 500KW in this wind speed interval.
As a kind of preferred embodiment, this patent current practice is in 1.5MW type, from 0~rated power, 1.5MW
