Abstract: A detection method and detection apparatus for a wind driven generator, and a computer-readable storage medium, a computer device and a detection system for executing the method. The method comprises: acquiring corresponding operation data of a wind driven generator within a preset time period; according to the operation data, then determining comprehensive data corresponding to the wind driven generator, wherein the comprehensive data is used for reflecting a continuous operation state of the wind driven generator within the preset time period; and when the comprehensive data exceeds a first data threshold, generating first alarm information corresponding to the wind driven generator, wherein the first alarm information is used for indicating that the wind driven generator is in an abnormal operation state within the preset time period, the abnormal operation state may cause the increase of a fatigue load of a wind driven generator unit, thereby shortening the service life of the unit, the first data threshold is less than a second data threshold, and the second data threshold is used for determining whether the wind driven generator has a fault. In this method, in response to the comprehensive data exceeding the first data threshold, a wind driven generator processing device can generate the first alarm information corresponding to the wind driven generator, such that the problem of a unit being damaged because the wind driven generator operates in an unhealthy operation state can be avoided to a certain extent.

Abstract: A method of controlling a wind turbine, wherein a minimum required hydraulic pressure represents a hydraulic pressure of at least one accumulator of the wind turbine which is required to pitch at least one blade of the wind turbine which is associated with the accumulator into a stop position of the wind turbine, and wherein a pitch angle represents a pitch angle of a normal of the at least one blade of the wind turbine relative to an incoming wind direction. The method includes (a) determining a minimum requirement function of the minimum required hydraulic pressure dependent on the pitch angle, (b) detecting a current hydraulic pressure in the at least one accumulator at a current pitch angle of the at least one blade, and (c) controlling the wind turbine such that the current hydraulic pressure is above the minimum required hydraulic pressure at the current pitch angle.

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: The present invention relates to control of a wind turbine in a stop process in response to a rotor stop signal. The rotor stop process comprises the steps of prior to receipt of the rotor stop signal, generating a stored pitch angle signal by storing pitch angle signals for at least a fraction of a rotor revolution, and determining at least one periodic component of the stored signal. The rotor blades of the wind turbine are controlled towards a feathering position using a pitch control signal containing the at least one periodic component.

Abstract: A method of operating a wind energy installation having a rotor with at least one rotor blade that is angularly adjustable by an adjustment drive. In response to the occurrence of at least one special operating case, in particular at least one malfunction case, the rotor blade is adjusted in a direction of a shutdown position by the adjustment drive. In the shutdown position, a supply of energy from an energy storage device to the adjustment drive is switched off and/or a pitch brake for holding the rotor blade in its current position is closed. In response to at least one activation signal, the rotor blade is adjusted by the adjustment drive in an adjustment mode of operation while the special operating case is still ongoing, in particular while the malfunction case is still ongoing.
