Integer, the method include：
, there is n platform power enhancement mode wind power generating sets in m platform power enhancement mode wind power generating sets are monitored in S210
In nominal power generating state when, based on current electric grid input power calculate electrical network current generation loss, wherein, n is big
In 0 and less than or equal to the integer of m；
S220, by n platform power enhancement mode wind power generating sets can hoisting power sum compared with current generation loss
Compared with, wherein, power enhancement mode wind power generating set can hoisting power be power enhancement mode wind power generating set actual power with
The difference of nominal power；And
S230, when n platform power enhancement mode wind power generating sets can hoisting power sum be more than current generation loss when, it is right
N platform power enhancement mode wind power generating sets are controlled, so that the power sum that n platform power enhancement mode wind power generating set is lifted
Equal to current generation loss.
In some instances, the method can also include when n platform power enhancement mode wind power generating sets can hoisting power
When sum is not more than current generation loss, n platform power enhancement mode wind power generating sets are controlled respectively and is generated electricity with actual power.
In some instances, in S210, wind power generating set whether is deposited in judging wind energy turbine set and reach nominal power, if
Nominal power is reached currently without wind power generating set, then now, power enhancement mode wind power plant and common wind energy turbine set do not have
It is variant, when exist one or more wind power generating set reach nominal power generate electricity when, power enhancement mode wind power plant is then
Power Control can be carried out to the power enhancement mode wind power generating set in wind energy turbine set by S220, to make up loss electricity, be entered
And increase wind park income.For example, when unit number is completely sent out more than or equal to one and be less than n platforms, it is now in reaching mark
Claim the power enhancement mode wind power generating set of power due to Power Limitation, lose part wind energy, can be by calculating current sending out
Electric loss, judge current n platforms power enhancement mode wind power generating set can hoisting power sum whether can more power generation loss, example
Such as, line loss is made up, if cannot make up, can controls to reach the n platform power enhancement mode wind-driven generators of nominal power
Group hoisting power is to actual power；If current n platform power enhancement mode wind power generating set can hoisting power sum can make up
Current line is lost, then can currently be needed hoisting power to share the power for reaching nominal power to each or a part strengthens
Type wind power generating set, for example, can be controlled according to current wind-resources around each power enhancement mode wind power generating set respectively

In some instances, when quantity m=n of power enhancement mode wind power generating set of nominal power is reached, wind energy turbine set now will
Bear max line and undermine the economic loss that an electricity consumption brings, after current line loss is calculated, still need to judge that current power lifting is
It is no to make up line loss, if it is then can currently be needed hoisting power to share to each or a part reaches nominal work(
The power enhancement mode wind power generating set of rate；If cannot make up, every power enhancement mode wind power generating set can be controlled
Hoisting power is to actual power.In some instances, current power generation loss, can be based on the current electric grid input power of wind energy turbine set
To calculate.In some instances, current power generation loss P0=(current electric grid input power/r)-current electric grid input power, its
In, r is loss coefficient, and the coefficient can be by obtaining according to the concrete line parameter circuit value of wind energy turbine set, and electric energy meter data, such as r
Can be with value as 0.95.
In some instances, the method can also include：When monitor current electric grid input power be more than electrical network input work
When the higher limit of rate is with current generation loss sum；Power Control is carried out to n platform power enhancement mode wind power generating sets, so that n
The output sum of platform power enhancement mode wind power generating set is equal to the higher limit and current generation loss of electrical network input power
Sum.In some instances, the method can also include monitoring that current electric grid input power is not more than electrical network input power
Higher limit with current generation loss sum when；N platform power enhancement mode wind power generating sets are controlled, so that n platform power
Enhancement mode wind power generating set is generated electricity with actual power.For example, when the multiple stage power enhancement mode wind-driven generator of generating field
When group is generated electricity with the power more than nominal power, it is possible that obtaining current electric grid input power deducts current power generation loss
When requiring to electricity volume more than grid dispatching center afterwards, it should be noted that Grid Central here is required to electricity volume
Can be understood as the higher limit of electrical network input power.In some instances, the higher limit of the electrical network input power can use relation
Formula is obtained：Total nominal power+current electric quantity loss-current electric grid the input work of the higher limit=generating field of electrical network input power
Rate.
In some instances, for example under strong wind weather, the fault rate of wind power generating set can than under little wind weather
Lifted, also, under strong wind weather, the economic loss that every wind power generating set is brought is also big than under little wind weather.In this feelings
Power enhancement mode wind-power electricity generation can also be controlled under condition by the Poewr control method of the wind power plant of the embodiment of the present invention
The power of the assembling unit further increases wind park income so as to make up the generated output loss caused by indivedual wind power generating set failures.Example
If nominal power is the wind park of 49.5MW, when wind park is under full power generating state, if wherein one wind-power electricity generation
Unit breaks down, its per hour electric quantity loss assume to calculate according to 1500kWh, about 750 yuan of economic loss, if multiple stage wind-force
Generating set long-time breaks down, and that economic loss will be inestimable.In power enhancement mode wind power plant, run into such
Situation, generating that can be by the Poewr control method of above-mentioned wind power plant to be brought by the wind power generating set of disorderly closedown
Loss.For example, it is assumed that there is 33 wind power generating sets in wind park, the nominal power of wind park is 49.5MW, is gone out in strong wind
Existing 3 disorderly closedowns, whole factory's generated output now is 45MW, if remaining wind power generating set adopts above-mentioned wind power plant
Poewr control method, whole factory's generated output can still ensure to reach 49.5MW.Do not considering to make up line loss and station-service electric loss
In the case of, total amount is that the power enhancement mode wind power plant of 33 power enhancement mode wind power generating sets can ensure that most 3
In the case that platform wind power generating set is because of disorderly closedown, whole factory's generated output reaches and can arrive nominal power, i.e. rated power.Assume
Under strong wind weather, the probability that every wind power generating set breaks down is identical, is 1%, and 33 wind power generating sets do not go out
The probability of existing disorderly closedown is about 71.8%, has the break down probability of shutdown of 1 wind power generating set to be about 23.9%, has 2
The probability that platform wind power generating set occurs shutting down simultaneously is about 3.9%, has 3 wind power generating sets while shutdown of breaking down
Probability is about 0.4%, and the probability of not more than 3 shutdown of breaking down is about 9.9675%, i.e., using above-mentioned wind power plant
Under strong wind weather, whole factory's generated output reaches nominal power generating to the power enhancement mode wind power plant of Poewr control method
Probability is promoted to about 99.9675% by about the 71.8% of common wind energy turbine set.Obviously, the lifting of probability means the income of wind park
Rate will also be lifted.
Fig. 3 is the application scenarios schematic diagram of the Poewr control method of the wind power plant of another embodiment of the present invention；Such as Fig. 3
Shown, when wind direction is blown over from west to east, the wind-resources of the wind power generating set of A circuits will be better than the wind power generating set of B circuits,
Now whole field wind power generating set will reach nominal power generating in part wind power generating set, and part wind power generating set is not
Reach nominal power generating state.As can be seen here, due to being affected by many factors such as wind park addressing, prevailing wind direction changes, wind
In power generation process, Jing is often met in the range of whole factory for power plant, is had the wind-resources around the wind power generating set of part preferable, is reached mark
Claim power generation, and the wind-resources around the wind power generating set of part are subject to other wind power generating set wake flow, geographical position etc.
The impact of factor, fails to reach the situation of nominal power generating.Also, reach around the wind power generating set of nominal power generating
Wind-resources it is excellent, but be subject to Power Limitation, part wind energy is have lost when nominal power is reached, synchronization is not up to marked
Wind-resources around title power wind power generating set are poor, and wind power generating set not yet reaches nominal power, in turn results in the whole audience
Wind power generating set be not up in nominal power rating.

Row compares；
S430, when the actual power of power enhancement mode wind power generating set is less than current generation loss with the difference of nominal power
When, control the first maximum power enhancement mode wind-force of the effective wind speed in n platform power enhancement mode wind power generating sets around which and send out
Group of motors is generated electricity with actual power.
For example, per Delta to around the wind power generating set of nominal power due to possessing different wind-resources, its power institute
The space that can be lifted is also different, and its room for promotion of the big group of motors of the excellent wind-force of wind-resources is relatively large, can basis
The current wind-resources situation of unit, i.e., it is with reference to the effective wind speed around wind power generating set, preferential to lift the best unit of wind-resources

Maximum the second power enhancement mode wind power generating set hoisting power in addition to the first power enhancement mode wind power generating set with
Make up current generation loss.For example, cannot still make up after the first power enhancement mode wind power generating set is lifted to actual power
Current power generation loss, then can be according to the size of Current ambient effective wind speed to reaching the wind power generating set of nominal power
It is ranked up, nominal power is lifted into actual power successively, the wind power generating set after power ascension is no longer participate in this wheel work(
Rate is lifted, until judging that the actual power of power enhancement mode wind power generating set is damaged not less than current generating with the difference of nominal power
It is time-consuming, control the maximum wind power generating set hoisting power of the currently active wind speed to make up current electric grid loss.In some examples
In, if here wheel power ascension process when not completing, the other wind-force unit for being not reaching to nominal power can
To utilize, then the wheel lifting process will also terminate.The generating of the uneven loss of wind energy distribution can be made up by said method
