Embodiment Construction

[0039] exist figure 1 shows a longitudinal sectional view of components of a wind energy installation which can be monitored by means of a method according to a particularly preferred embodiment of the invention. The wind energy equipment is represented by 100 as a whole, and its drive train is represented by 10 .

[0040] The drive train 10 shown consists essentially of a main shaft 1 on which a rotor 20 is mounted, a transmission 2 and a generator shaft 3 . The transmission 2 can be, for example, a three-stage transmission usually used in wind energy installations. The invention can likewise be used in gearless wind turbines or wind power plants.

[0041] The main shaft 1 is non-positively connected to a rotor 20 , for example a rotor rotor or a rotary vane rotor. The generator shaft 3 can be connected to a generator 40 via a coupling 30 . Main shaft 1 , transmission 2 , generator shaft 3 and generator 40 are supported with corresponding mechanisms, enclosed in a housing...

Abstract

The invention relates to a method for monitoring a state of a drive train, in particular of a wind power plant, which drive train has at least one component which is mechanically connected to a rotating element of the drive train and on which at least one acceleration sensor is arranged at a distance from a rotational axis of the drive train, which acceleration sensor rotates about the rotational axis of the drive train at the distance, wherein a signal of the at least one acceleration sensor of the at least one component is sensed in terms of its timing at at least one rotational speed of the rotating element and is examined for interference frequencies which correspond to damage in the drive train.

Description

technical field [0001] The invention relates to a method for monitoring the state of, in particular, a drive train of a wind energy installation, a computing unit for carrying out the method, and a correspondingly arranged monitoring device. Background technique [0002] The most uninterrupted operation of a wind energy installation (WEA) is an important prerequisite for its economy. In particular, unplanned outages due to damage to the drive line or to the rotor blades result in considerable repair costs and frequently lead to safety incidents. [0003] In order to avoid this disadvantage, so-called condition-oriented maintenance is often provided in WEA, which is based, for example, on the basis of vibration-based condition monitoring (Condition Monitoring, CM) of the rotor blades in corresponding condition monitoring devices or systems (Condition Monitoring Systems, CMS ) is implemented. By means of this measure, for example, incipient damage in the rotor blade can be d...
