Description
Technical field
The present invention relates to a kind of monitoring methods more particularly to a kind of for monitoring the side of different type blower fan system state
Method.
Background technique
The fan condition that current fan monitoring system all uses code representative different is sorted out convenient for system, but every set wind
Machine has the code of oneself, and a monitoring system can only realize the monitoring for certain specific type blower, if a wind power plant has
The blower of several types, then each type of blower requires to dispose a set of monitoring system, and operator on duty needs while checking
Several monitoring systems can grasp the operating status of each blower, operate and be inconvenient.It is logical that the invention proposes one kind
With type monitoring system, it can be achieved that the monitoring of multiple type blowers.Wind power plant need to only dispose a set of generic system, so that it may realize more
Type monitors simultaneously.
Summary of the invention
To solve the above problems, the present invention provides a kind of universal fan monitoring method, this method passes through one shell-like of setting
State logic calculates mechanism, the state code of different blowers is unified, in this way only by a monitoring system, so that it may
Realize the monitoring to multiple type blowers, as shown in Figure 1, the method for the present invention specifically includes:
1) judge whether the data of the blower output of monitoring interrupt, if data are to interrupt, the state of blower is appointed as
Blower is offline；If data be it is non-interrupted, enter step 2)；
2) judge whether the data of blower output represent blower and ration the power supply state, blower state of rationing the power supply is actively to limit wind
The state of blower is appointed as rationing the power supply by the state of machine normal power generation if data represent blower and ration the power supply state；
If data do not represent blower and ration the power supply state, enter step 3)；
If 3) data do not represent blower and ration the power supply state, at least there are three kinds of states in blower, respectively to wind state, normal
Generating state, shutdown status；Described to refer to that real wind speed is less than blower threshold wind velocity to wind state, blower is in idle running to wind shape
State, blower fault-free；The normal power generation state refers to that real wind speed is between incision blower and cut-out wind speed, and blower is normally sent out
Electricity cuts wind speed, refers to the minimum wind speed that wind power generating set starts to generate electricity by way of merging two or more grid systems, usually 3 meters or 3.5 meters.Such as it cuts
Wind speed is 3 meters, when wind speed reaches 3 meters, and fan blade starts to drive generator rotation, into power generation mode；Cut-out wind speed: refer to wind
The maximum wind velocity that power generator group is generated electricity by way of merging two or more grid systems is more than after this wind speed, and blower will be shut down, and is no longer generated electricity, and generally 25 meters.Example
If wind speed reaches 25 meters, blower since blade is unable to rotate too fast (being afraid of that vane stress is too big), shut down by blower brake.Just and high-speed rail
Equally, speed is too just dangerous fastly, so highest is also with regard to 350m/h；The shutdown status refers to that blower does not generate electricity completely；
The particular state of blower under non-state of rationing the power supply further is judged, if data are represented to wind state, by the shape of blower
State is set to wind；If data represent normal power generation state, fan condition is positioned into normal power generation；If data, which represent, shuts down shape
Fan condition is then positioned and is shut down by state.
In above-mentioned steps, because data code is the unique information source that system judges fan condition, sentence first
Disconnected should be data whether be interrupt state, only in the normal situation of data receiver could to other particular states into
Row judgement.State in most common the four of blower, respectively rations the power supply, to wind, normal power generation, shutdown, just will appeal four kinds of states
As the primary stage of judgement, after qualitative to these four state interpretations, judge to this particular state in four under state.
Preferably, in the step 2), the state of rationing the power supply includes at least two states, respectively ration the power supply shutdown and limit
Electricity power generation, the shutdown status of rationing the power supply refer to that blower receives halt instruction, shutdown shutdown the reason is that grid requirements are rationed the power supply；The limit
Electric generating state refers to that real wind speed is between incision blower and cut-out wind speed, and blower receives limit power instruction, downrating；
Further include following steps in the step 2): if the state of blower is to ration the power supply, judgement is rationed the power supply blower under state
Fan condition, is set to shutdown of rationing the power supply by particular state, the shutdown status if data representative is rationed the power supply；If data, which represent, limits power generation shape
Fan condition is then set to drop power output of rationing the power supply by state.
Preferably, if data represent shutdown status in the step 3), further judge data whether represent blower by
Tired state, the blower existence situation refer to because external environmental condition makes blower not work；If data represent blower involvement, will
Fan condition is set to blower existence situation.
Preferably, the blower existence situation in the step 3) includes at least five kinds of states, respectively strong wind involvement, high temperature
Involvement, low temperature involvement, frost involvement, thunder and lightning involvement；
The strong wind involvement refers to that real wind speed is higher than cut-out wind speed, fan parking state；
The high temperature involvement refers to that realistic temperature is higher than blower normal operating temperature, fan parking state；
The low temperature involvement refers to realistic temperature lower than blower normal operating temperature, fan parking state；
The frost involvement refers to that blower is influenced shutdown status by freezing weather；
The thunder and lightning involvement refers to blower due to the influence shutdown status by thunder and lightning relationship；
In the step 3), if fan condition is set to blower involvement, blower under blower existence situation is further judged
Particular state, if data represent strong wind existence situation, by fan condition be set to strong wind involvement；If data represent high temperature involvement
Fan condition is then set to high temperature involvement by state；If data represent low temperature existence situation, by fan condition be set to low temperature by
It is tired；If data represent frost existence situation, fan condition is set to frost involvement；If data represent thunder and lightning involvement, by wind
Machine state is set to thunder and lightning involvement.
Preferably, in the step 3), if data do not represent blower involvement, further judge whether data represent event
Hinder shutdown status, the disorderly closedown refers to blower because of failure cause shutdown status, if data representing fault is shut down, by blower
State positioning failure is shut down.
Preferably, in the step 3), if data representing fault is shut down, further judge whether data represent maintenance
Button is opened, when the maintenance button refers to that blower is maintained, it is necessary to and the button of unlatching, if data represent maintenance, button is opened,
Fan condition is then set to Breakdown Maintenance state.
Preferably, in the step 3), if data not shut down by representing fault, further judge whether data represent dimension
It protects button to open, when the maintenance button refers to that blower is maintained, it is necessary to which the button of unlatching, if data represent maintenance, button is opened
It opens, then fan condition is set to and is actively repaired；If data do not represent maintenance, button is opened, and fan condition is positioned as stopping manually
