Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] see figure 1 with figure 2 , the generator set state monitoring system of the present invention includes a rotational speed detection unit 1, a rotational speed correction unit 2, a speed regulation unit 3, a signal acquisition unit 4, a signal processing unit 5, an input unit 6, a control unit 7, a display unit 8, a storage unit 9 and emergency stop unit 10, wherein:

[0025] The rotational speed detection unit 1, the rotational speed correction unit 2 and the speed regulation unit 3 are sequentially connected; the rotational speed detection unit 1 detects the shaft speed of the generator, obtains the rotational speed signal and transmits it to the rotational speed correction unit 2, and the rotational speed correction unit 2 compares the rotational speed signal with the prestored rotational speed Compared with the standard, it is corrected when the standard is e...

Abstract

The invention discloses a condition monitoring system of a generator set. The condition monitoring system comprises a rotating speed detection unit used for detecting the speed of a rotating shaft of a generator, a rotating speed correction unit used for correcting a rotating speed signal, a speed regulation unit used for regulating the speed of the rotating shaft of the generator, a signal acquisition unit used for collecting all kinds of detection signals of the generator, a signal processing unit used for preprocessing the detection signal, an input unit used for inputting a command, a control unit used for sending a control command and analyzing a signal processing result, a storage unit used for storing the signal processing result, and a display unit used for displaying the condition of the generator set. According to the condition monitoring system, the speed of the rotating shaft of the generator is corrected, and all kinds of collected detection signals are pre-processed to obtain the purer detection signal, so that the generator set is accurately and comprehensively monitored.

Description

technical field [0001] The invention relates to the field of generators, in particular to a generator set state monitoring system. Background technique [0002] As the wind power generation technology becomes more and more mature, the installed capacity of wind power generators is getting bigger and bigger. Of course, in order to prevent major accidents and for the sake of safe production, it is necessary to conduct comprehensive and accurate monitoring of the operating status of the generator sets. Particularly important. The general monitoring system only collects and analyzes various status signals of the generator during operation, and then directly determines whether it is faulty or not. Not only the influence of the rotation speed of the generator shaft on various signal sizes is ignored, but also the fine preprocessing of these signals is lacking, so that the accuracy of the obtained results is not enough, and the accuracy of monitoring is reduced. Contents of the ...
