Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
Embodiment 1
Fault code quotes method in a kind of wind-driven power generation control system, as shown in Figure 1, the method for quoting can wrap
Include following steps:
Step S11: the fault code is activated；
Step S12: judge whether the fault code is dominant symbols code, wherein the dominant symbols code is corresponding
In the machine halt trouble of wind power generating set；
If being judged as YES, S13 is thened follow the steps: the corresponding machine halt trouble of the dominant symbols code is answered
Position；
If the machine halt trouble resets successfully, S14 is thened follow the steps: not quoting the dominant symbols code, and keep
The wind power generating set operates normally；
If the machine halt trouble reset is unsuccessful, thens follow the steps S15: quoting the dominant symbols code.
In the present embodiment, the fault code may include dominant symbols code, hidden failure code and derivative failure
Code.Wherein, dominant symbols code can correspond to the machine halt trouble of wind power generating set, such as: hardware fault, theft-resistant link chain event
Barrier, variable pitch communication failure, current transformer communication failure, monitoring communication failure etc..Hidden failure code can correspond to wind-power electricity generation
The non-stop-machine failure of only alarming of unit, such as: cacophonia etc. when the of short duration exceeded, wind wheel of temperature rotates.Derivative failure generation
Code is the failure chain reaction as caused by other failures and the fault code generated, for example, when the hydraulic cylinder of feather speed regulation
When falling off, the failure of wind wheel rotation cacophonia can be derived；When third harmonic excitation thyristor short circuit, temperature can be derived
Abnormal failure etc..
Further, it can respectively include representing its type in the code segment of dominant symbols code and hidden failure code
Mark, the mark can be the composite sequence of Serial No., alphabetical sequence or digital alphabet, such as: can use 11 as
The mark of hardware fault in dominant symbols code, use 12 as theft-resistant link chain failure in dominant symbols code mark；21 can be used
Mark etc. as temperature short time exception in hidden failure code.
Further, the mark can be located at any row of code segment.
Preferably, the mark is located at the first row of code segment, in order to distinguish different failure generations according to the mark
The type of code.
It please also refer to Fig. 1, Fig. 2.In the present embodiment, specifically execute step S11 when, can by following steps into
Row:
Step S21: judge whether the fault code meets default activation condition；
If being judged as YES, S22 is thened follow the steps；If being judged as NO, S24 is thened follow the steps；
Step S22: after the first preset time, judge whether the corresponding failure of the fault code still has；
If being judged as YES, S23 is thened follow the steps: if being judged as NO, thening follow the steps S24；
Step S23: the fault code is activated；
Step S24: the fault code is not activated.
Specifically, the default activation condition can be preset threshold value or threshold range, and it is pre- to be also possible to certain
If failure operation state be continued above predetermined time period.Such as: it can be more than 50% conduct by speed regulating motor voltage fluctuation
The default activation condition of speed regulating motor failure.Another example is: wind wheel can be rotated and failure operation state that generator does not generate electricity
Continue activation condition of the 25s as Generator Excitation Faults, the failure fortune that wind wheel is sometimes fast and sometimes slow when wind speed can be changed little
Row state continues the default activation condition that 40s fails as governor governor spring.
First preset time can set form for a variety of different times such as second grade, minute grades.For example, can incite somebody to action
First preset time is set as 20s, if the corresponding failure of the fault code still remains, then described in activation after 20s
Fault code, if (the practical detection by control system of the failure misses the corresponding failure vanishes of the fault code within 20s
Difference causes), then the corresponding fault code of the failure is not activated, and effectively reduces the overall quantity of fault code.
It should be noted that those skilled in the art can be accustomed to according to specifically demand and breakdown maintenance and be it is various not
Same failure sets different default activation condition and/or the first preset time, as long as can rationally identify and activate failure
Code, the embodiment of the present invention to this with no restriction.
In addition, if the fault code is judged as being hidden failure code step S16 can be executed: described in record
The corresponding fault type of fault code, and the fault code is not quoted.
If the fault code is judged as being dominant symbols code, at this point, being not to quote the dominant symbols at once
Code will not control wind power generating set shutdown at once, but to the corresponding machine halt trouble of the dominant symbols code
It is resetted.Wherein, the process of the reset can be referred to as fault traversing.
Specifically, Fig. 1, Fig. 3 be please also refer to, step S13: the machine halt trouble corresponding to the dominant symbols code
Reset to carry out as follows:
Step S31: one or many resets are carried out to the machine halt trouble in the second preset time；
Step S32: the number of the reset is compared with default number of resets；
If any primary reset is so that the machine halt trouble disappears, the machine halt trouble resets successfully；
If the number of the reset is greater than the default number of resets, and the machine halt trouble still has, then described to stop
Machine failure reset is unsuccessful.
In this embodiment, those skilled in the art can according to specific requirements the second preset time of setting of adaptability
And number of resets, second preset time can set form for a variety of different times such as second grade, minute grades.
For example, the second preset time can be set as 30s, set number of resets to 5 times, if in 30s, it is any one
It is secondary to reset so that machine halt trouble disappears, then it is assumed that reset successfully, if failure still has after resetting by 5 times, then it is assumed that multiple
Position is unsuccessful.
Further, if the machine halt trouble resets unsuccessful, quoting after the dominant symbols code can also be to
The wind power generating set sends stopping signal, so that the wind power generating set is shut down, and notifies maintenance personal in time to stopping
Machine failure repairs.Specifically, the stopping signal can by wireless communication or the mode of wire communication is sent.
If the machine halt trouble is successfully resetted, the normal operating condition of wind power generating set is kept, while to failure
Event (reseting procedure) is passed through to be recorded.
