It obtains the accurate power control value of every Fans, and is assigned to wind turbine.
It is shown according to field research and feedback data, above-mentioned traditional approach mainly has following deficiency：
1st, the variation of wind turbine wind speed frequently results in the variation of power of fan fan-out capability comparatively fast, and power control is difficult, is susceptible to
The phenomenon that being exported beyond target power, and be difficult to realize in the control range of target power, it is maximized to control wind turbine output
Power.
2nd, it is excessively complicated since it is desired that active power ability, reactive power ability to every Fans carry out complex calculation
Algorithm operation control software reaction can be caused slow, power of fan control slows.
Invention content

From the foregoing, it will be observed that after method using the present invention, active power does not need to compute repeatedly the wind field active power upper limit, directly
Connect by current point on the basis of active power in real time, according to the ratio of active command and real-time active power, amplification in proportion or
The active command of separate unit wind turbine is reduced, can ensure that its active command received per Fans is active in current wind turbine automatically
Within the scope of power capability.And reactive power calculates its ability value according to wind turbine current active power, further according to nonfunctional
Power and the ratio relation of instruction instruct to distribute, and are not in cause to influence having for wind turbine because reactive power instruction distribution is excessively high
Work(power output.The method of the present invention has certain versatility, the various initial values actually controlled, maximum value, minimum value, guarantor
Shield value can all need adjustment in real time according to the use of user, reduce a large amount of human resources.
In specific application, can wind turbine be divided by several classes according to wind turbine real-time running state：
I class wind turbines：Special state wind turbine, overtemperature or artificial non-serving pattern lower limit work(；
II class wind turbines：Output power is less than or equal to minimum definite value；

Wherein, minimum definite value is wind turbine minimum acceptable active power limit value, and setting value is less than this value wind turbine
Can report an error shutdown.Active power set-point is the power command value distributed for separate unit wind turbine.During air-blower control, wind field
Output power allow upper lower limit value be：When there is super generating or few heat condition, super generating or the percentage of few hair amount and command power
Ratio, this value adjust requirement and wind field actual conditions that can change manually according to net.
As shown in Figure 1, in concrete application example, the detailed process of active power controller is：
Step 1：After control instruction is obtained, first step processing is carried out to control instruction, is determined whether to according to wind field spy
Different situation arranges instruction actual value.
Step 2：Judge control instruction value, such as larger than wind field rated generation capacity, be that rated power is distributed per Fans,
Complete distribution；If current active output is less than control instruction, then do not control；If output power is more than the lower limit allowed, and
Less than the upper limit of permission, then do not adjust；
Step 3：Obtain the separate unit wind turbine mean power set-point obtained according to control instruction value and wind turbine power generation number of units.
Step 4：If all Group III wind turbines of wind turbine at this time, do not adjust；
Step 5：If the first sub-distribution, calculate control instruction and account for the current ratio always exported, then II, Group III wind turbine are pressed
This ratio is reduced, and completes distribution；
Step 6：If control instruction is distributed for non-first time, the predistribution of control instruction, I class wind turbines are carried out：Without
Control, makes it freely generate electricity, but the part that its output power is dispatched as a whole；II class wind turbines：Active power is given as most
Lower bound definite value；Group III wind turbine：Active power is given as real output；IV class wind turbines：Active power, which gives, to be remained unchanged.
Step 7：The secondary distribution of control instruction, and to pre-allocating remaining instruction, in two kinds of situation, if it is more than zero,
Then it is averagely allocated to II classes, Group III and IV class wind turbines；If less than zero, represent and also have super generating, need to continue the portion of super generating
Divide and proportionally reduced from the instruction of the secondary distribution of II, III, IV class wind turbine, until instruction and the predistribution of secondary distribution are surplus
The amount of remaining instruction is in the threshold range of algorithm permission, completes distribution.
Step 9：Additional spilling revision directive in configuration is averagely allocated to II, III, IV class wind turbine.
In the present embodiment, to be PLC control system be set by reactive power according to active power situation, power factor
It calculates to judge that current wind turbine needs to send out reactive power amount.Wherein, it is as follows to calculate method for power factor：
It is possible thereby to release reactive power and be：
In view of the active power power generation situation of current wind turbine, while also to consider wind turbine rated reactive power and idle work(
The limitation of rate is adjustable lower limiting value.Again because real power control and idle control are run, therefore the control of reactive power is not simultaneously
It can influence the control of active power.So the calculating of reactive power is to carry out operation on the basis of the real-time active power of wind turbine
's.As shown in Fig. 2, detailed process is as follows：
Step 1: starting, long-range reactive command Q is obtained；

Total reactive power upper limit value Q of real-time wind field can be obtainedtot；
Step 3:
Step 4: as X is more than or equal to 1, illustrate under present case, the idle output of wind field is to be unable to reach instruction certainly
Numerical value, reactive power upper limit value is calculated as apportioning cost according to its real-time effective power meter per Fans at this time, is temporarily terminated,
Wait for startup next time.If X is less than 1, illustrate to need to limit the reactive power that wind turbine exports.
Step 5: as X is less than 1, then X is multiplied by the reactive power power capability of current every controllable wind turbine, obtained value
The reactive command value being as assigned to per Fans.Distribution terminates.
In conclusion the method for the present invention is suitable for wind-power electricity generation and control technology on wind electricity generation unit and wind-force hair
