Description
Technical field
The present invention relates to a kind of check methods for anemobiagraph more particularly to a kind of for wind-driven generator anemobiagraph
Online check method.
Background technique
The major function of wind-driven generator anemobiagraph is to participate in the control of wind-driven generator, comprising: judges that cutting speed is used
Yu Qiji；Judgement cut out speed for shut down etc., especially when wind speed is more than to cut out under speed conditions, the inaccuracy of anemobiagraph is possible
It causes wind-driven generator to fail to cut out in time, causes safety accident.Therefore the calibration of wind-driven generator anemobiagraph becomes non-
Often important, such as application No. is 201810742962.2 Chinese patents.
And on the other hand, regularly anemobiagraph is calibrated, work difficulty is big, loss is more, therefore, is badly in need of one kind just
Anemobiagraph state check method that is prompt, feasible, convenient and carrying out under the premise of not influencing wind-driven generator and running.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of high degree of automation,
Online check method at low cost, using safe wind-driven generator anemobiagraph.
The present invention solve the above problems used by technical solution be: it is a kind of for wind-driven generator anemobiagraph in line core
Checking method, characterized in that process is as follows:
The wind-driven generator group compared is determined according to primary condition；
The wind-driven generator group primary condition of comparison need to meet simultaneously the following conditions: (1) in the wind-driven generator group compared
Constituent parts moment coefficient of dispersion is less than or equal to 5% in the historical wind speed data that each wind-driven generator anemobiagraph measures；(2) compare
Pair wind-driven generator group in each hub of wind power generator Height Standard difference and the ratio between average value be less than or equal to 2%；
(3) interval of each wind-driven generator is not more than 40 rotor diameters in the wind-driven generator group compared；(4) wind-force compared
The orientation of generating set group is with a line and vertical with direction prevailing；
When in wind-driven generator A anemobiagraph numerical value single in the wind-driven generator group of comparison and the wind-driven generator group compared
The case where the ratio between data arithmetic average of other wind-driven generator anemobiagraphs is less than or equal to 80% occurs, and when occurring accumulative
Between in 24 hours be greater than or equal to 6 hours, then assert single wind-driven generator A anemobiagraph be second level surveillanced object；Work as comparison
Wind-driven generator group in single wind-driven generator A anemobiagraph numerical value and other wind-force in the wind-driven generator group that compares
The case where the ratio between data arithmetic average of generator anemobiagraph is less than or equal to 80% occurs, and it is small 24 that the cumulative time occurs
When it is interior be greater than or equal to 12 hours, then assert single wind-driven generator A anemobiagraph be level-one surveillanced object.
Further, the coefficient of dispersion is each wind-driven generator in the wind-driven generator group of per time instance comparison
The ratio between the standard deviation for the air speed data that anemobiagraph measures and arithmetic average.
Further, the second level surveillanced object needs see whether to upgrade to level-one surveillanced object for continuous 7 days.
Further, the level-one surveillanced object need to stop single wind-driven generator A work, replace or calibrate single wind
Power generator A anemobiagraph.
Compared with prior art, the present invention having the following advantages that and effect:
(1) working condition of the invention that can be realized verification anemobiagraph under the premise of wind-driven generator is non-stop-machine, and existing skill
Art be regular dismounting or replacement anemobiagraph, heavy workload, and dismantle and installation process there are the risks of secondary damage.
(2) present invention can batch at the assessment wind-driven generator anemobiagraph state of group, improve and verify efficiency, for asking
The anemobiagraph emphasis of topic is verified, and can extend calibration cycle to the stable anemobiagraph of performance, realizes fining calibration, reduce at
This.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Referring to Fig. 1, the online check method for wind-driven generator anemobiagraph in the present embodiment, process is as follows:
The wind-driven generator group compared is determined according to primary condition；
The wind-driven generator group primary condition of comparison need to meet simultaneously the following conditions: (1) in the wind-driven generator group compared
Constituent parts moment coefficient of dispersion is less than or equal to 5% in the historical wind speed data that each wind-driven generator anemobiagraph measures；(2) compare
Pair wind-driven generator group in each hub of wind power generator Height Standard difference and the ratio between average value be less than or equal to 2%；
(3) interval of each wind-driven generator is not more than 40 rotor diameters in the wind-driven generator group compared；(4) wind-force compared
The orientation of generating set group is with a line and vertical with direction prevailing；
