Abstract: A method for preventing damage in a bearing of a generator of an electrical power system having a power conversion assembly with a first converter coupled to a second converter, and the power conversion assembly electrically coupled to the generator. Further, the method includes monitoring a phase current and voltage of the first converter. The method also includes calculating a common mode power using the phase current and the voltage of the first converter. Moreover, the method includes comparing the common mode power to a predefined power threshold. The method also includes determining whether the common mode power is indicative of degradation in at least one of a bearing insulation or a ground brush based on the comparison of the common mode power to the predefined power threshold.

Abstract: A flange connection for a wind turbine, in particular a blade flange connection, having—a first flange part, in particular a blade receptacle of a rotor blade hub, a second flange part, in particular a rotor blade flange, and multiple bolts which hold the second component against the first flange part in a connected state, wherein the bolts are each screwed to the first flange part. It is proposed that the at least two bolts are in each case connected to one another by a tension means, a sensor arrangement, which detects a change in a tensile force transmitted by the tension means, being actively connected to the tension means. A wind turbine and a method for monitoring the flange connection of the wind turbine are also proposed.

Abstract: A wind turbine is provided, including a hub, rotor blades, wherein each rotor blade is rotatably supported at or in the hub by a pitch bearing, a pitch control device for changing a pitch angle of the rotor blades, and a measurement system for capturing a sensor signal in or at the pitch bearing and for changing the pitch angle by the pitch control device as a function of the sensor signal to prevent failure of the pitch bearing due to a lack of lubrication, wherein the sensor signal represents a change in vibration, noise and/or temperature in or at the pitch bearing. Due to the fact that the pitch angle can be changed as a function of the sensor signal, lubrication of the pitch bearing is ensured throughout the lifetime of the pitch bearing. Unnecessary pitch movements can be prevented.

Abstract: Embodiments disclosed herein may include methods, systems, and tangible, non-transient, computer-readable media having instructions thereupon for determining a damage state of a wind turbine gearbox. A method performed, executed on a processor of a system, or implemented by a processor as instructions, may comprise producing a damage state diagnostic, producing a damage progression model for the wind turbine gearbox using operational data and a state transition function, and combining the damage state diagnostic with the damage progression model using a hybrid prognostics model to produce a probability distribution of a current damage state estimate. Producing the damage state diagnostic may comprise obtaining a measurement dataset for the wind turbine gearbox, integrating field-operator-provided intelligence into the measurement dataset, normalizing the measurement dataset with respect to a known failure behavior for the wind turbine gearbox, and combining the normalized measurement dataset with the known failure behavior to produce the damage state diagnostic.
