Abstract
A kind of multiaxis shake monitoring point wind turbine Shaft chattering fluctuation judge with the method for processing, belong to Mechanical course field.It shakes signal fluctuation for the axis in fan monitoring system, provides a kind of fluctuation judgment method.Fluctuated when an axis shakes, programmable controller will release axis shake it is chain；When unit break down or monitoring signals circuit in common portion break down when, to avoid erroneous judgement, fluctuated when more than two axis shake, programmable controller all axis that will come into operation shake " chain ", chain will be shut down when reaching chain shutdown value.It can effectively prevent axis from shaking detection device damage or the signal that shakes of dummy shaft caused by signal line interferes leads to wind turbine chain shutdowns shutdown, therefore have very high use value.
Description
Technical field
The present invention is that a kind of multiaxis monitoring point wind turbine Shaft chattering fluctuation that shakes judges method with processing, belongs to Mechanical course neck
Domain.Feature is shaken signal fluctuation for the axis in fan monitoring system, provides a kind of fluctuation judgment method, and shake for axis
Fluctuation status is shielded or is restored axis and shaken the guard method of chain control.
Background technology
In blower detecting system, it is the important monitoring information of wind turbine that axis, which shakes,.Wind turbine generally has multiple axis to shake test point,
The shake signal detection of test point, the processing of each axis is made of multiple equipment, is generally shaken change by axis shake fore-lying device, the axis of probe, axis that shake
The equipment such as device, signal isolator, programmable controller are sent to form.Since the equipment of signal being transferred through is more, equipment is any to be set
Signal interference is generated in the standby circuit broken down or transmit signal, can cause signal fluctuation, forms glitch, the company of arrival
Locking machine value may result in fan parking accident.This method describes a kind of method, can effectively prevent axis shake detection device damage
The signal that shakes of dummy shaft caused by bad or signal line interferes leads to chain the shutdowns shutdown of wind turbine, therefore has very high use value.
Invention content
The object of the present invention is to provide a kind of Shaft chattering fluctuations to judge the method with processing.Shaft chattering fluctuation judges that principle is：It can
Programmable controller is shaken the changing value of signal in a short time by judging axis, to judge whether the axis signal that shakes is fluctuated.
The method of processing is：Fluctuated when an axis shakes, programmable controller will release axis shake it is chain；Work as machine
Group break down or monitoring signals circuit in common portion break down when, to avoid erroneous judgement, when more than two axis shake
It fluctuates, programmable controller all axis that will come into operation shake " chain ", chain will be shut down when reaching chain shutdown value.
Shaft chattering fluctuation judges as follows with the concrete methods of realizing of processing：
Step 1: shaking for each axis, " chain " and " unlock " two buttons are set in the programmable controller, in axis
It shakes under " unlock " state, Shaft chattering fluctuation releases or comes into operation " chain " in vain, " unlock " alert state is shown in controller；Only
When axis shakes in " chain ", Shaft chattering fluctuation releases or comes into operation " chain " effectively.
Step 2: Shaft chattering fluctuation alarm and the Reset button are arranged in the programmable controller.After Shaft chattering fluctuation alarm, need
The Reset button is put, alarm could be eliminated.
Step 3: being shaken actual operating state according to axis when unit operation, shake for any one axis, set the sampling period as
A seconds.Per A seconds to sampling primary sample value, it is denoted as X1, the real time value that the axis after sampling in A seconds shakes is denoted as X2.According to technique
And equipment operation condition, set best Shaft chattering fluctuation decision content Y.There is the axis that fluctuates number of shaking and is denoted as C.
According to field data detection and phenomenon of the failure data statistics experience, if the range that axis shakes is M.
General value is M*30%≤Y≤M*60%.
Step 4: when axis shakes and comes into operation chain, detected value when by judging axis jolt ramming judges Shaft chattering fluctuation and handles.
(1) it shaking for any one axis, as ︱ X1-X2 ︱ >=Y, then it is assumed that there is larger instantaneous variation in the axis numerical value that shakes,
The axis shakes real time value for spurious signal, and axis, which shakes, to be fluctuated, while C+1；Programmable controller cuts off the company that the axis shakes automatically
Lock, and export warning message.
(2) when the axis for more than two fluctuations occur shake, i.e. C >=2, programmable controller comes into operation the company that all axis shake automatically
Lock, the warning message that output wave moving axis shakes.Once axis shakes, value reaches chain shutdown value, and automatic linkage is shut down.
This method can effectively prevent axis from shaking detection device damage or the dummy shaft signal that shakes causes caused by signal line interferes
The chain shutdown of wind turbine is shut down, therefore has very high use value.
Description of the drawings
Fig. 1 be multiaxis shake test point wind turbine Shaft chattering fluctuation judge and process chart
Specific implementation mode
Below by 4 axis shake monitoring point gas-blowing engine for.
1, it shakes for each axis, " chain " and " unlock " two buttons is set in the programmable controller, the axis that comes into operation shakes
" chain " makes Shaft chattering fluctuation judge effective.
2, Shaft chattering fluctuation alarm and the Reset button are set in the programmable controller.After Shaft chattering fluctuation alarm, need a little
The Reset button could eliminate alarm.
3, it is shaken actual operating state according to equipment axis, sets the sampling period as 1 second.Every 1 second to sample primary sample value,
It is denoted as X1, the real time value that the axis after sampling in 1 second shakes is denoted as X2.According to technique and equipment operation condition, sets best axis and shake
It is 50 to fluctuate decision content Y.(range that in this instance, axis shakes is 120, and Y value is set according to the actual conditions that axis when unit operation shakes
It is the 42% of range).There is the axis that fluctuates number of shaking and is denoted as C.
4, it shakes in axis when coming into operation " chain ", detected value when by judging axis jolt ramming judges Shaft chattering fluctuation and handles.
(1) it shaking for any one axis, as ︱ X1-X2 ︱ >=Y, then it is assumed that there is larger instantaneous variation in the axis numerical value that shakes,
The axis shakes real time value for spurious signal, and axis, which shakes, to be fluctuated, while C+1；Programmable controller cuts off the company that the axis shakes automatically
Lock, and export warning message.
(2) when the axis for more than two fluctuations occur shake, i.e. when C >=2, programmable controller comes into operation the company that all axis shake automatically
Lock, the warning message that output wave moving axis shakes.Once axis shakes, value reaches chain shutdown value, and automatic linkage is shut down.
