Show, which mainly may include following steps:
Step S110: in current detection cycle, the revolving speed of wind power generating set is obtained according to the preset sampling period
Value.
The variation of the revolving speed and wind speed of wind power generating set is closely related, and the revolving speed of unit can be corresponding with the variation of wind speed
Ground is adjusted, and therefore, the rapids in region locating for wind-power electricity generation group can be assessed based on the variation of the revolving speed of wind power generating set
The variation of stream.Since wind-driven generator is the power input equipment of wind power generating set, the revolving speed of wind power generating set is as wind
Important input in power generator group control strategy, can reflect the situation of change of wind speed more in real time, and tach signal with
By anemobiagraph wind velocity signal collected compared to more accurate, therefore, the revolving speed of wind power generating set can be commented more accurately
Estimate the variation of turbulence intensity, accurately identifies extreme turbulent flow operating condition.
Since extreme turbulent flow operating condition belongs to extreme operating condition in short-term, by the way that detection cycle is arranged in the embodiment of the present invention,
Judge whether occur extreme turbulent flow operating condition in the detection cycle respectively in each detection cycle.Wherein, detection cycle is excellent

Step S120: it records in the tachometer value got in current detection cycle greater than the tachometer value of setting speed value
Number.
Step S130: if the number recorded in the current detection period is greater than the set value, determine that wind power generating set is in
Extreme turbulent flow operating condition.
It is understood that the integer in the result that above-mentioned setting value is obtained no more than detection cycle divided by the sampling period
Value, i.e. setting value can not be greater than the total number of the tachometer value of the wind power generating set got in a detection cycle.
In the wind power generating set design specification of IEC61400-1 3rd Edition, the model of extreme turbulent flow is defined
(ETM), what turbulence intensity reflected is the fluctuation situation of wind speed, and turbulence intensity is bigger, and air-flow is more unstable, and fluctuation is bigger, is caused
The load that wind power generating set is subjected to is bigger.Compared with normal turbulent flow operating condition, wind speed will appear extreme turbulent flow operating condition interior in short-term
Multiple biggish fluctuation therefore, can be in each detection cycle so as to cause the repeatedly variation in short-term of wind power generating set revolving speed
The initial time start recording current detection period in occur wind power generating set tachometer value be greater than setting speed value
Number, if the number recorded in the detection cycle is not more than setting value, then explanation is in current detection in current detection end cycle
In period, region locating for wind power generating set is in a relatively stable state, it is possible to determine that does not occur extreme rapids
Operating condition is flowed, enters next detection cycle at this time, continues the tachometer value for obtaining wind power generating set according to the above-mentioned sampling period, weight
The tachometer value of wind power generating set is greater than the number of above-mentioned setting speed value in this current detection period of new record, further according to note
The number of record and above-mentioned setting value determine whether extreme turbulent flow operating condition occur, to realize to whether wind power generating set is in
The lasting detection of extreme turbulent flow operating condition.
As soon as then explanation is being worked as if the number of record has been above setting value when being not finished in a current detection period
Multiple biggish variation occurs in short-term for wind speed in preceding detection cycle, it is possible to determine that wind power generating set has met with extreme turbulent flow work
Condition.
In the embodiment of the present invention, records in the tachometer value got in current detection cycle and turn greater than setting speed value
Before the number of speed value, which can also include:
History wind-resources parameter based on wind power generating set region, according to the normal turbulent flow operating condition of standard and standard pole
End turbulent flow operating condition is emulated；
According to the sampling period, wind-driven generator corresponding to the normal turbulent flow operating condition of a detection cycle internal standard is counted respectively
Second turn of wind power generating set corresponding to first revolving speed of group and the extreme turbulent flow operating condition of a detection cycle internal standard
Speed；
According to the first revolving speed and/or the second revolving speed, the setting speed value is determined.
Specifically, in order to be more in line with above-mentioned setting speed value and the actual conditions in region locating for wind power generating set,
And guarantee normal turbulent flow operating condition when do not trigger extreme turbulent flow operating condition control strategy (including but not limited to drop power or drop revolving speed or
The control of variable pitch), so that wind power generating set is in normal power generation, avoids unnecessary generated energy from losing, in the embodiment of the present invention
In, mean wind speed, atmospheric density, the wind speed frequency of different periods (but can be not limited to according to the history wind-resources parameter in region
Distribution and the parameters such as wind energy frequency distribution), and according to the normal turbulence model of IEC standard and extreme turbulent flow condition model respectively into
The emulation of row normal turbulent flow operating condition and extreme turbulent flow operating condition, and according to above-mentioned detection cycle and sampling period, respectively statistic record
Multiple tachometer values of two kinds of operating condition apparatus for lower wind generating sets in one detection cycle, according to more under the normal turbulent flow operating condition of record
Multiple second tachometer values under a first tachometer value and/or extreme turbulent flow operating condition, determine setting speed value.
In the embodiment of the present invention, setting speed value is determined according to the first revolving speed and/or the second revolving speed, comprising:
Maximum value in first tachometer value is determined as setting speed value.
By the way that the maximum value in the first tachometer value is determined as setting speed value, then by configuring corresponding setting value,
The case where being judged as extreme turbulent flow operating condition to avoid normal turbulent flow operating condition appearance, avoids extreme turbulent flow operating condition regulating strategy
Triggering the problem of leading to the lower power production of wind power generating set.
In the embodiment of the present invention, after determining setting speed value according to the first tachometer value and/or the second tachometer value, the knowledge
Other method can also include:
It determines and is greater than in the first revolving speed number and the second tachometer value that are greater than setting speed value in the first tachometer value respectively
Second revolving speed number of setting speed value；
Setting value is determined according to the first revolving speed number and the second revolving speed number, wherein setting value is greater than the first revolving speed number
And less than the second revolving speed number.
Due to that after determining above-mentioned setting speed value, can count to obtain the first tachometer value (corresponding normal rapids respectively
Flow operating condition) in be greater than it is big in the first revolving speed number and the second tachometer value (corresponding extreme turbulent flow operating condition) of the setting speed value
In the second revolving speed number of the setting speed value, due to setting value be for distinguishing extreme turbulent flow operating condition and normal turbulent flow operating condition,
Therefore, the first revolving speed number and the second revolving speed number can be obtained based on above-mentioned statistics, determination obtains being more in line with wind-power electricity generation
The setting value of regional environment locating for unit.
In the embodiment of the present invention, by configuring setting value to the numerical value greater than the first revolving speed number, normal rapids is avoided
The regulating strategy that stream operating condition is judged as under extreme turbulent flow operating condition, extreme turbulent flow operating condition is triggered and leads to the hair of wind power generating set
The problem of electricity reduces.
In an alternate embodiment of the present invention, the normal turbulent flow operating condition and extreme turbulent flow work of wind power generating set can be designed
Condition, the design conditions can be the normal turbulent flow operating condition and extreme turbulent flow operating condition under the rated wind speed of design wind power generating set,
It is also possible under the incision wind speed to each wind speed section of cut-out wind speed for separately designing wind power generating set normal turbulent flow operating condition and pole
Hold turbulent flow operating condition.Normal turbulent flow operating condition and pole in the case where designing each wind speed section of the incision wind speed of wind power generating set to cut-out wind speed
When holding turbulent flow operating condition, the normal turbulent flow operating condition in a detection cycle under each wind speed section can be counted respectively according to the sampling period
Wind-power electricity generation corresponding to extreme turbulent flow operating condition under first tachometer value of corresponding wind power generating set and each wind speed section
Second tachometer value of unit, it is available by comparing the first tachometer value corresponding to each wind speed section and the second tachometer value respectively
Greater than maximum (top) speed in the first tachometer value and less than the range of speeds of maximum (top) speed in the second tachometer value under each wind speed section, and can
To determine setting speed value according to the range of speeds corresponding under each wind speed section.
Since for each of above-mentioned each wind speed section wind speed section, wind power generating set is under normal turbulent flow operating condition
The case where there is no the minimum values that wind power generating set revolving speed is greater than the range of speeds, and there are wind-force under extreme turbulent flow operating condition
Rotary speed of generator group is greater than the case where maximum value of the range of speeds, therefore, can be according in the range of speeds under each wind speed section
Determine the setting speed value for extreme turbulent flow operating mode's switch, and setting speed value determining at this time is more in line with wind-power electricity generation
Regional environment locating for unit keeps the recognition result of extreme turbulent flow operating condition more accurate, at this point, may further be by setting
Setting value is stated, makes to be no more than the setting value greater than the number of setting speed value under normal turbulent flow operating condition, to ensure that normal rapids
It will not be identified as extreme turbulent flow operating condition under stream operating condition, avoid the extreme turbulent flow operating condition regulating strategy of triggering, generated energy is caused to damage
It loses.
In practical applications, the range of speeds according to corresponding to each wind speed section determines that the concrete mode of setting speed value can
There are many, for example, it may be selecting a tachometer value in the range of speeds corresponding to one of wind speed section as setting
Tachometer value, be also possible to using from the minimum speed in the range of speeds corresponding to each air speed value as setting speed value, can be with
It is that the minimum speed value in all ranges of speeds is made average or maximum (top) speed value to be averaged, using calculated mean value as setting
Velocity amplitude, can also be by with corresponding to the immediate air speed value of mean value of incision wind speed and cut-out wind speed in the range of speeds
One tachometer value or minimum speed value, can also will be immediate with the rated wind speed of wind power generating set as setting speed value
A tachometer value in the range of speeds corresponding to wind speed section is as setting speed value etc..
It is understood that in practical applications, above-mentioned setting speed value can also directly be set based on experience value.
As a specific example, Fig. 2 and Fig. 3 respectively illustrate detection cycle be 600S, sampling period 0.02S
When, extreme turbulent flow operating condition apparatus for lower wind rotary speed of generator group versus time curve schematic diagram and normal turbulent flow under a certain wind speed section
