Description
Technical field
The present invention relates to wind power generation field more particularly to a kind of control methods of wind power generating set pre-cooling.
Background technique
Currently, the wind power generating set Starting mode of wind power plant is the incision wind speed for reaching design requirement according to measurement wind speed
Just enter Booting sequence afterwards, cuts wind speed for grid type blower, refer to the minimum wind speed for reaching grid-connected conditions, by
More and more in the wind power generator group of wind power plant, the wind power generator group distributed areas of same wind power plant are wider, this to open
The dynamic process time spent if causing all units that overall startup is wanted to complete is longer, so that wind energy cannot be made full use of.
Summary of the invention
It is an object of the invention to disadvantages described above, provide one kind and make full use of wind energy resources, shorten wind power plant entirety unit
All control methods of the wind power generating set pre-cooling of starting time.
In order to achieve the above object, the technical scheme is that, a kind of control method of wind power generating set pre-cooling,
Itself the following steps are included:
Step 1, wind power plant wind power prediction system prediction to wind farm wind velocity will reach setting after the setting value T1 period
It is worth wind speed V1；
Step 2, using the wind azimuth after the wind power plant T1 period of wind power prediction system prediction as refer to wind azimuth；
Step 3, the wind power generating set of wind power plant standby mode are inclined to start with reference to wind azimuth as target wind azimuth
Boat；
Step 4, the unit to yaw with reference to wind azimuth as target wind azimuth, respectively judge its wind in During yaw
Whether speed reaches design incision wind speed, is to enter step 5, otherwise enters step 6；
Step 5: stopping yaw, and enter step 8；
Step 6: when unit orientation with reference to wind azimuth it is consistent, stop yawing, then enter step 7；
Step 7: blade is expanded to the angle, θ of setting by unit in advance, when unit wind speed reaches incision wind speed, then into step
Rapid 8；
Step 8: wind power generating set opens machine by normal flow.
The method have the benefit that: predict the wind power plant of the following setting period in advance by wind power prediction system
Wind speed will be increased to setting value, then using the following setting period of wind power prediction system prediction when wind power plant wind azimuth as whole
The reference wind azimuth of a all standby mode wind power generating sets of wind power plant；All standby mode wind power generating sets are to refer to
Wind azimuth is yawed as each unit wind azimuth value pre-cooling；When the orientation of wind power generating set reaches and refers to wind direction side
Position is consistent, and wind power generating set stops yaw and blade is expanded to the angle, θ of setting to variable pitch in advance, works as wind-driven generator
Group wind speed is then carried out by normal Booting sequence when reaching incision wind speed.The control of wind power generating set pre-cooling can greatly shorten
Entire wind power plant unit opens the machine time, makes full use of wind energy resources, and unit is allowed to enter generating state as early as possible, promoted wind power plant and
The generated energy in wind-power electricity generation base.
Detailed description of the invention
Fig. 1 is control method of embodiment of the present invention flow diagram.
Specific embodiment
Below in conjunction with attached drawing, the invention will be further described.
Reference attached drawing 1, a kind of control method of wind power generating set pre-cooling comprising following steps:
Step 1, wind power plant wind power prediction system prediction to wind farm wind velocity will reach setting after the setting value T1 period
It is worth wind speed V1；
Step 2, using the wind azimuth after the wind power plant T1 period of wind power prediction system prediction as refer to wind azimuth；
Step 3, the wind power generating set of wind power plant standby mode are inclined to start with reference to wind azimuth as target wind azimuth
Boat；
Step 4, the unit to yaw with reference to wind azimuth as target wind azimuth, respectively judge its wind in During yaw
Whether speed reaches design incision wind speed, is to enter step 5, otherwise enters step 6；
Step 5: stopping yaw, and enter step 8；
Step 6: when unit orientation with reference to wind azimuth it is consistent, stop yawing, then enter step 7；
Step 7: blade is expanded to the angle, θ of setting by unit in advance, when unit wind speed reaches incision wind speed, then into step
Rapid 8；
Step 8: wind power generating set opens machine by normal flow.
The wind farm wind velocity for predicting the following setting period in advance by wind power prediction system will be increased to setting value, then with
Wind power plant wind azimuth is as all standby mode wind of entire wind power plant when the following setting period of wind power prediction system prediction
The reference wind azimuth of power generator group；All standby mode wind power generating sets are using reference wind azimuth as each unit wind direction
The yaw of orientation values pre-cooling；When the orientation of wind power generating set reaches consistent with reference to wind azimuth, wind power generating set is stopped
Only yaw and blade is expanded to the angle, θ of setting to variable pitch in advance, when wind power generating set wind speed reaches incision wind speed
Then carried out by normal Booting sequence.What the control of wind power generating set pre-cooling can greatly shorten entire wind power plant unit opens machine
Time makes full use of wind energy resources, and unit is allowed to enter generating state as early as possible, promotes the power generation in wind power plant and wind-power electricity generation base
Amount.
