Abstract

The invention relates to a control method for pre-start-up of a wind generating set. The wind speed of the wind power plant in the future set time period is increased to a set value by the wind power predicting system in advance, then the wind direction azimuth of the wind farm is taken as the reference wind direction azimuth of the wind generating set in all standby states of the whole wind park when the wind power generating set is predicted by the wind power predicting system. All standby-state wind generating sets can start the yawing in advance with the reference wind direction azimuth as the wind direction azimuth value of each unit. When the orientation of wind power generating set is consistent with reference to wind azimuth, wind power generating set stops driftage and blade is expanded to the set angle, Theta,so as to become oar in advance simultaneously, then carried out by normal booting sequence when the wind speed of the wind power generating set reaches the cut-in wind speed. The start-up control of the wind power generator unit can shorten the start time of the whole wind power unit greatly, making full use of the wind energy resources, and letting the unit enter the power generation status as soon as possible, so as to increase the generated power quantity of the wind farm and wind power generation base.

Description

A kind of control method of wind power generating set pre-cooling
Technical field
The present invention relates to wind power generation field, more particularly, to a kind of control method of wind power generating set pre-cooling.
Background technology
At present, the wind power generating set Starting mode of wind energy turbine set is to reach the incision wind speed of design requirement according to measurement wind speed Just enter Booting sequence afterwards, incision wind speed is for grid type blower fan, refers to reach the minimum wind speed of grid-connected conditions, by Wind power generator group in wind energy turbine set gets more and more, and the wind power generator group distributed areas of same wind energy turbine set are wider, this open Dynamic flow process causes all units to want the overall startup spent time if completing longer, thus wind energy can not be made full use of.
Content of the invention
It is an object of the invention to disadvantages described above, one kind is provided to make full use of wind energy resources, shorten wind energy turbine set entirety unit All control methods of the wind power generating set pre-cooling of starting time.
For realizing object above, the technical scheme is that, a kind of control method of wind power generating set pre-cooling, It comprises the following steps:
Step 1, wind energy turbine set wind power prediction system prediction to wind farm wind velocity will reach setting value wind after the setting value t1 period Fast v1;
Step 2, using the wind azimuth after the wind energy turbine set t1 period of wind power prediction system prediction as with reference to wind azimuth;
Step 3, the wind power generating set of wind energy turbine set holding state are to start driftage with reference to wind azimuth for target wind azimuth;
Step 4, the unit to go off course for target wind azimuth with reference to wind azimuth, each judge that its wind speed is in During yaw No reaching designs incision wind speed, is then to enter step 5, otherwise enters step 6;
Step 5: stop driftage, and enter step 8;
Step 6: when unit orientation is with reference to the consistent then stopping driftage of wind azimuth, 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 enters step 8;
Step 8: wind power generating set opens machine by normal flow.
The method have the benefit that: the following wind energy turbine set setting the period is predicted in advance by wind power prediction system Wind speed will be increased to setting value, then using wind power prediction system prediction following set the period when wind energy turbine set wind azimuth as whole The reference wind azimuth of all holding state wind power generating set of individual wind energy turbine set;All holding state wind power generating set are with reference Wind azimuth is gone off course as each unit wind azimuth value pre-cooling;When the orientation of wind power generating set reaches and reference wind direction side Position is consistent, and wind power generating set stops driftage and blade is expanded to the angle, θ of setting thus becoming oar in advance, works as wind-driven generator Group wind speed is then carried out by normal Booting sequence when reaching incision wind speed.Wind power generating set pre-cooling controls and can greatly shorten Whole wind energy turbine set unit open the machine time, make full use of wind energy resources, allow unit enter generating state as early as possible, lifting wind energy turbine set and The generated energy in wind-power electricity generation base.
Brief description
Fig. 1 is embodiment of the present invention control method FB(flow block).
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to the drawings 1, a kind of control method of wind power generating set pre-cooling, it comprises the following steps:
Step 1, wind energy turbine set wind power prediction system prediction to wind farm wind velocity will reach setting value wind after the setting value t1 period Fast v1;
Step 2, using the wind azimuth after the wind energy turbine set t1 period of wind power prediction system prediction as with reference to wind azimuth;
Step 3, the wind power generating set of wind energy turbine set holding state are to start driftage with reference to wind azimuth for target wind azimuth;
Step 4, the unit to go off course for target wind azimuth with reference to wind azimuth, each judge that its wind speed is in During yaw No reaching designs incision wind speed, is then to enter step 5, otherwise enters step 6;
Step 5: stop driftage, and enter step 8;
Step 6: when unit orientation is with reference to the consistent then stopping driftage of wind azimuth, 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 enters step 8;
Step 8: wind power generating set opens machine by normal flow.
The following wind farm wind velocity setting the period is predicted in advance by wind power prediction system and will be increased to setting value, then with During the following setting period of wind power prediction system prediction, wind energy turbine set wind azimuth is as whole wind energy turbine set all holding states wind The reference wind azimuth of power generator group;All holding state wind power generating set are using reference wind azimuth as each unit wind direction Orientation values pre-cooling is gone off course;When the orientation of wind power generating set reach with reference to wind azimuth consistent, wind power generating set is stopped Only go off course and blade is expanded to the angle, θ of setting thus becoming oar in advance, when wind power generating set wind speed reaches incision wind speed Then carry out by normal Booting sequence.Wind power generating set pre-cooling controls can greatly shorten whole wind energy turbine set unit to open machine Time, make full use of wind energy resources, allow unit enter generating state, the generating in lifting wind energy turbine set and wind-power electricity generation base as early as possible Amount.
