Embodiment two
The method flow diagram for wind power generating set icing control method another embodiment that Fig. 2 provides for the present invention, be
A kind of specific implementation of embodiment as shown in Figure 1.As shown in Fig. 2 the wind power generating set icing control method is specifically wrapped
Include：
S201, by the ice condition of each blade of freezing sensor real-time detection wind power generating set, and is monitored in real time
Operational factor during the ambient parameter of wind power generating set local environment and operation；The specific implementation procedure of the step can be found in step
Rapid 101 corresponding contents.
In the present embodiment, temperature parameter and humidity parameter are mainly included in above-mentioned ambient parameter；Wind power generating set correspondence
Ambient parameter meet ice-formation condition and specifically include：Said temperature parameter is less than temperature threshold, and humidity parameter is more than humidity threshold
Value.Generally, when temperature and humidity meets certain threshold range simultaneously in air, it can determine that the environment has reached ice-formation condition.
For example, for northern China most area, said temperature threshold value is about -10 DEG C, and humidity threshold is about 60%；For me
State's south most area, said temperature threshold value is about 2 DEG C, and humidity threshold is about 80%.
In specific detection and measurement, the result of detection available parameter B of freezing sensor feedback represents that wherein B=1 is represented
Freeze, B=0 represents not freeze；The corresponding ambient parameter of unit monitored meets the situation available parameter H tables of ice-formation condition
Show, wherein H=1 represents to meet ice-formation condition, H=0 sufficient ice-formation conditions with thumb down；In the corresponding fortune of the above-mentioned unit monitored
In row parameter, the present embodiment is corresponding during choosing but being not limited to unit work to be run under certain wind speed section with minimum speed
Time as weigh unit whether occur the parameter of operation exception, the parameter represents that wherein G=0 represents normal operation, G with G
=1 expression mile abnormality, G=2 represent that severe is abnormal, corresponding to be defined as：When unit above-mentioned certain wind speed section under with minimum
Rotating speed operation time in continuous special time period add up be less than the very first time threshold value when it is corresponding be defined as normal operation,
Add up when the time that unit is run under above-mentioned certain wind speed section with minimum speed in continuous special time period more than first
Time threshold and it is corresponding during not less than the second time threshold be defined as mile abnormality, when unit under above-mentioned certain wind speed section with
The time of minimum speed operation corresponding is defined as severe when adding up in continuous special time period more than the second time threshold
Abnormal, wherein very first time threshold value is less than the second time threshold.Specifically, above-mentioned certain wind speed section can be according to each unit difference
And local environment and it is different on occurrence, usual arranges value is higher, such as wind speed be more than 8m/s.Set higher specific
The reason for wind speed section, is, under relatively low wind speed section, and whether the rotating speed that unit is run in itself is just relatively low (freezes without necessarily closing with blade
System), maintain essentially in minimum speed；And wind speed it is relatively low when, even blade freezes to the safety and reliability of unit
It is that influence is less.Above-mentioned special time period can be 10min.Above-mentioned very first time threshold value can be 1min, the second time threshold
Value can be 8min.In concrete application scene, by reference to the occurrence of tri- parameters of B, H, G, can targetedly it set
Fixed corresponding icing control operation scheme.

When the ambient parameter answered meets ice-formation condition, if the time that wind power generating set is run under certain wind speed section with minimum speed exists
Add up in continuous special time period more than very first time threshold value and not less than the second time threshold, then trigger wind power generating set
Perform the operation operation that freezes；
Specifically, as above-mentioned parameter B=1, H=1, G=1, by synthetic determination, current turbines vane is most likely in
Slight icing condition.Generally, blade remains to work under slight icing condition, and simply generated output can decline, and
Other aspect institutes are affected smaller.At this moment, unit can be triggered and perform the icing operation operation being directed under slight icing condition；
Such as, but not limited to：The minimum pitch angle and minimum speed of wind power generating set increase current wind generating set are triggered, and
Reduce rotating speed torque coefficient, it is respectively reached corresponding modification amplitude threshold.Wherein, the modification amplitude threshold of each parameter can
With advance or interim setting and modification, to cause unit to remain to keep or increasing electricity output in the case where blade slightly freezes, from
And meet index demand of the unit to generated energy.
S203, when result of detection shows that each blade of wind power generating set has frozen, and the wind power generating set pair monitored
When the ambient parameter answered meets ice-formation condition, if the time that wind power generating set is run under certain wind speed section with minimum speed exists
Add up more than the second time threshold, then to trigger wind power generating set and perform icing shutdown operation in special time period；
Specifically, as above-mentioned parameter B=1, H=1, G=2, by synthetic determination, current turbines vane is most likely in
Severe icing condition.Generally, blade is under severe icing condition, unit not only cisco unity malfunction, and the operation being forced is also
Very big negative effect can be brought to the safety and reliability of unit.At this moment, it is necessary to carry out shutdown operation to unit.This implementation
In example, the shutdown operation used is specially that triggering unit is completed to machine of becalming with 180 degree.
So-called 180 degree is to machine of becalming：The impeller of blower fan is shut down with 180 degree back to direction windward, and the halt mode can be with
Ensure under blade severe ice-formation condition, windward, such blade icing position will change blade trailing edge, i.e., it is main in blade
The trailing edge of aerofoil profile, and leading edge freezes and will be eased.Because the influence that leading edge freezes to Airfoil Aerodynamic Performance is more serious, because
This, this closing method can reduce the time that unit is restarted after turbines vane terminates, when improving the generating of unit
Between, and then improve the generated energy of unit.
Certainly, if above-mentioned parameter B, H, G occurrence occur in that the situation beyond above two combination, characterize and work as
Preceding turbines vane there is a possibility that the very little that freezes, it may be determined that not frozen for blade, now, and unit can be using normal control
Strategy, normal operation.
Above-mentioned steps 202 and 203 can be considered the refinement mode of step 102.
The wind power generating set icing control method that the present embodiment is used, on the basis of embodiment illustrated in fig. 1, gives
When external environment condition meets ice-formation condition, the exception level reflected according to the operational factor of unit carries out the specific reality of icing control
Existing mode, such as when unit is mile abnormality, use can improve the icing operation operation of generated energy；When unit is that severe is abnormal
When, use can be reduced terminate after startup time when being again started up unit icing shutdown operation, ensureing unit peace
While full property and reliability, ensure the generated energy of unit as far as possible, stabilize generating efficiency.
