Fig. 2 shows the partial schematic diagram of wind power generating set according to an embodiment of the invention.As shown in Figure 2, the core component of wind power generating set comprises: blade 210, main shaft 220, gear-box 230, generator 240 and tower cylinder 250.First wind power generating set converts wind energy to mechanical energy by multiple blade 210, relends and helps the transmission system such as main shaft 220, gear-box 230 and generator 240 mechanical energy to be converted to electric energy, thus realize wind-power electricity generation.Wherein, blade 210 is that wind power generating set absorbs the critical component of wind energy, is outdoorly for a long time operated in rugged environment, is difficult to the potential faults such as the fatigue crack that the destruction avoiding being subject to the factors such as humidity corrosion, fitful wind or thunderbolt and long-play produce; Main shaft 220 and gear-box 230 are connected blade 210 and generator 240, realize the main load-bearing component of Wind resource change and transmittance process, when wind power generating set meets with fitful wind, of short duration and frequently impulsive load will be delivered to main shaft 220 and gear-box 230 from blade 210, cause the faults such as bearing wherein and gear wear and tear, spot corrosion, crackle, surfacial spalling, broken teeth, flank of tooth fatigue, gummed; Generator 240 is responsible for mechanical energy being converted to electric energy also for electrical system is powered, in variable working condition and elecromagnetic environment, easily there is the faults such as Generator Vibration is excessive, generator overheating, bearing running hot, rotor/stator coil short, rotor broken bar and insulation damages in long-time running; And the orientation of tower cylinder 250 and stability are the prerequisites guaranteeing that above-mentioned wind-power electricity generation process is carried out smoothly.The fault of these parts all will cause the abnormal running of wind power generating set.
Therefore, in order to carry out early warning to the fault of wind power generating set exactly more comprehensively, in an embodiment of the present invention, multiple parts of the wind power generating set that the total state monitoring method of wind power generating set is monitored comprise: the blade of wind power generating set, main shaft, gear-box, generator and tower cylinder, the then state of multiple parts of Real-Time Monitoring wind power generating set in the method, for each parts, whether break down according to these parts of its condition adjudgement and comprise:
1, the blade of wind power generating set is monitored: the vibrational state of each blade of monitoring wind power generating set, judges whether to there is the blade broken down according to the vibrational state of each blade.
In the particular embodiment, above-mentioned observation process is: the noise signal gathering each blade, obtains the frequency domain character of the noise signal of each blade, judges whether to there is the blade broken down according to the frequency domain character of the noise signal of each blade.Wherein, the frequency domain character of noise signal comprises: the parameters such as the root-mean-square value of the frequency domain amplitude of noise signal, the mean value of the frequency domain amplitude of noise signal, the frequency domain amplitude of noise signal and the frequency domain distribution of noise signal, and the frequency domain character of noise signal can reflect the characteristic such as decibel, energy, frequency distribution of noise signal.In the present embodiment, the process of the frequency domain character failure judgement of the above-mentioned noise signal according to each blade comprise following one or more:
