Abstract
The invention discloses a monitoring device and monitoring method for vibration of a redundancy type wind turbine generator and belongs to the technical field of wind power generation. The monitoring device comprises two sensors, a signal processor and a monitoring server, wherein the two sensors are arranged on a monitoring part of the wind turbine generator; the signal processor is connected with the two sensors; and the monitoring server is connected with the signal processor. According to the monitoring method, measuring values of the two sensors are compared by the signal processor, and the error report information is sent to the monitoring server only when the difference of the measuring values exceeds an error scope. According to the invention, one sensor is added as a redundancy device, the measuring values of the sensors are periodically collected, the measuring values meeting an error standard are taken as the data for spectral analysis, and the influence of a sensor precision difference on the monitoring precision for the vibration of the wind turbine generator is reduced.
Description
Technical field
The invention discloses redundancy-type wind generating set vibration monitoring device and monitoring method, belong to the technical field of wind-power electricity generation.
Background technology
Monitoring System of Fan Vibration has obtained the attention of owner and complete blower factory at present, and for monitoring blower fan fortune long-term safety reliability service provides new means, scientific basis has been set up in maintenance and the replacing of the large critical component of attaching most importance to.
Senser element as the fan vibration detector is " eyes " and " ear " that detect each position vibration, in system, play a very important role, its reliably working is the decisive role of system reliability, since the vibration monitoring sensor be close to vibration source near, work under bad environment, easily cause sensor failure or deterioration in accuracy, especially in the measurement of some key position, in case the sensor abnormality measured signal can not truly reflect the actual vibration situation of unit under test, cause system's erroneous judgement, miss opportunity of combat when serious, cause irremediable loss.
Summary of the invention
Technical matters to be solved by this invention is the deficiency for the above-mentioned background technology, and redundancy-type wind generating set vibration monitoring device and monitoring method are provided.
The present invention adopts following technical scheme for achieving the above object:
The redundancy-type wind generating set vibration monitoring device comprises two sensors, signal processor, monitor server, and described two sensor settings are monitored the position at aerogenerator; The input termination sensor of described signal processor, output termination monitor server;
Described sensor is used for the vibration signal that detects is converted to electric signal;
Described signal processor is used for the relatively measured value of interior two sensors of each sampling period;
Described monitor server sends the information that reports an error to detecting server when the difference of measured value exceeds error and scope.
Redundancy-type wind generating set vibration monitoring method comprises the steps:
Step 1 is settled two sensors at aerogenerator to be monitored position;
Step 2, signal processor relatively connect the measured value of a sensor:
When the difference of two measurement value sensors was within error range, the mean value of getting two measurement value sensors carried out spectrum analysis and determines the vibration position;
Otherwise, send the information of reporting an error to monitor server.
The present invention adopts technique scheme, have following beneficial effect: the present invention makees redundance unit by increasing a sensor, periodicity pick-up transducers measured value, with the measured value of the coincidence loss standard data as spectrum analysis, reduce because the poor impact on wind electrical equipment unit vibration monitoring precision of sensor accuracy.

Sensor is used for the vibration signal that detects is converted to electric signal, and signal processor is used for the relatively measured value of interior two sensors of each sampling period, and monitor server sends the information that reports an error to detecting server when the difference of measured value exceeds error and scope.
Redundancy-type wind generating set vibration monitoring method comprises the steps:
Step 1 is settled two sensors in aerogenerator to be monitored position (such as bearing, gear case, generator, cabin);
Step 2, signal processor relatively connect the measured value of a sensor:
When the difference of two measurement value sensors was within error range, the mean value of getting two measurement value sensors carried out spectrum analysis and determines the vibration position;
Otherwise, send the information of reporting an error to monitor server.
In sum, the present invention makees redundance unit by increasing a sensor, and pick-up transducers measured value periodically with the measured value of the coincidence loss standard data as spectrum analysis, reduces because the poor impact on wind electrical equipment unit vibration monitoring precision of sensor accuracy.
