Abstract
The invention provides a wind power plant power control algorithm for prolonging the service life of a set, wherein the algorithm comprises an algorithm for improving power and an algorithm for reducing power. P maximum output is calculated by acquiring P current total power, and P current total power, P maximum output and P set value are compared. When power is required to be improved, whether or not a draught fan is required to be started is intelligently judged to meet the requirement, and when power is required to be reduced, whether or not the draught fan is required to be stopped is intelligently judged to meet the requirement, so that reduction in the service life of the set and difficulty in continuously meeting the issuing instruction of the power control system due to frequent regulation of the output of the single draught fan caused by the randomness of wind, the stability and timeliness of the power control system are ensured, and loss of generating capacity caused by the failure of the power control system is reduced.

S3, compare PEIAJWith PSetting valueSize,
3.1, P is worked asSetting value＞ PEIAJ＞ PCurrent total power, then start to start a certain off-duty blower fan, treat (RRun number of units+ 1) typhoon
When the gross capability of machine tends towards stability, then compare PCurrent total powerWith PSetting valueSize, if PSetting valueWith PCurrent total powerDifference more than PMaximum difference,
Then continue to start blower fan, so circulate, until PSetting valueWith PCurrent total powerDifference at PMaximum differenceIn the range of stop start blower fan, if
PSetting valueWith PCurrent total powerDifference at PMaximum differenceIn the range of, then start to regulate (RRun number of units+ N) gross capability of Fans, allow it meet
PSetting valueRange of error in stable operation；
3.2, P is worked asEIAJ＞ PSetting value＞ PCurrent total power, then the current First power of fan run is set to rated power, treats
Its power reaches PSeparate unit EIAJTime, if PSetting valueWith PCurrent total powerDifference more than PMaximum difference, then the second Fans merit of will currently running
Rate is set to rated power, so circulates, until PSetting valueWith PCurrent total powerDifference at PMaximum differenceIn the range of stop certain Fans merit
Rate is set as rated power, if PSetting valueWith PCurrent total powerDifference at PMaximum differenceIn the range of, then start to regulate current RRun number of unitsTyphoon
The gross capability of machine, allows it meet PSetting valueRange of error in stable operation；
S4, compare PEIAJWith PSetting valueSize,
4.1, P is worked asEIAJ＞ PCurrent total power＞ PSetting value, from current operation, blower fan removes a Fans calculating PEIAJIf,
The P of a Fans is removed in certain timeEIAJ＞ PSetting value, then it is not involved in P removingEIAJThat Fans calculated is shut down, so
Rear regulation (RRun number of units-1) gross capability of Fans, allows it meet PSetting valueRange of error in stable operation；If within a certain period of time
Remove the P of a FansEIAJ＜ PSetting value, then start to regulate RRun number of unitsThe gross capability of Fans, allows it meet PSetting valueError model
Enclose interior stable operation.
Further, described PEIAJ=RRun number of units×PSeparate unit EIAJ, RRun number of unitsBlower fan number of units is currently run for wind energy turbine set,
PSeparate unit EIAJBlower fan separate unit EIAJ is run for current.
Further, described PSeparate unit EIAJStandard dynamic power curve according to every Fans original design and currently every
The 3s mean wind speed that blower fan is measured, i.e. WMean wind speedCalculate and obtain.
Further, described PMaximum differenceFor PEIAJWith PCurrent total powerDifference.
Beneficial effects of the present invention: when needing to improve power, reaches to want the need of starting blower fan by intelligent decision
Ask, when needing to reduce power, reach requirement again by intelligent decision the need of stopping blower fan, it is to avoid random because of wind
Property, frequently regulation separate unit blower fan is exerted oneself and the reduction unit service life, the unit that exist are difficult to persistently meet power regulating system
Under the problem that sends instructions, it is ensured that the stability of power regulating system and promptness, decrease because of power regulating system fault
Loss generated energy.
