Embodiment 1

[0040] According to the embodiment of the present invention, an embodiment of a fault monitoring method for wind turbines is also provided. It should be noted that this embodiment can be applied in fault monitoring of wind turbines. Parameters to determine the working state of the wind turbine, and according to the working state of the wind turbine to give an early warning of the abnormal working time of the wind turbine, thereby reducing the misjudgment of the working state of the wind turbine, and achieving the technical effect of accurately judging the working state of the wind turbine .

[0041] At present, after a certain component of the wind turbine fails, other components related to the failed component may also fail. Therefore, maintenance personnel of the wind turbine need to spend a lot of manpower and material resources to repair the failed wind turbine. If the components of the wind turbine that are about to fail are maintained in advance before the components of ...

Abstract

The invention discloses a wind power generator fault monitoring method, device and system. The method comprises the steps of receiving multiple parameters from a target wind power generator serving asa monitoring object, wherein the parameters at least comprise the external environment temperature of the wind power generator, the working condition parameters of the wind power generator and the assembly temperatures of multiple assemblies of the wind power generator; utilizing an assembly abnormity detection model for the assemblies for determining assemblies with work abnormity in the targetwind power generator based on the parameters received from the target wind power generator, and determining whether or not the target wind power generator breaks down based on the determined assemblies with work abnormity in the target wind power generator. By means of the method, device and system, the technical problem in the prior art that misjudgment of the working state of a wind power generator is caused since the working state of the wind power generator is only determined according to the temperature of a unit is solved.

Description

technical field [0001] The present invention relates to the field of fault early warning, in particular to a method, device and system for fault monitoring of wind turbines. Background technique [0002] A wind generator, namely a wind motor, is a kind of electrical equipment that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. After the wind turbine is installed and operated, the mechanical components of the wind turbine will gradually wear out. In addition, the operating conditions of the wind turbine may also cause uncontrollable deterioration of the mechanical components of the wind turbine. In addition, if a certain mechanical component of the wind turbine is damaged during operation, chain structural damage will often occur, that is, other components will be damaged, and the repair cost of the wind turbine is relatively high, and the time to repair the fault is relatively long. [0003] At present, ...
