摘要:
A method for operating a wind turbine includes receiving a value of a sensor and comparing the value with a reference, determining depending on the comparison between the value with the reference whether a malfunction of the wind turbine is present; determining the cause of the malfunction of the wind turbine depending on at least one of: the sensor type or the measured value, wherein the cause determination includes: automatically creating a first list including at least one possible cause of the malfunction depending on the sensor type or the measured value; and automatically creating a second list including a sequence of at least two steps, wherein a first step of the second list is based on the a cause selected from the first list and a second step of the second list is automatically determined based on a result of the first step.
摘要:
A functionality test method for a technical system having at least one technical component to be regularly tested. The method including the steps of defining a test interval by setting a minimum time interval and a maximum time interval between two successive tests of the technical component, defining a test range for a decision parameter, sensing an actual value of the decision parameter, and performing a functionality test of the technical component if the minimum time interval between two successive tests of the technical component has elapsed and the sensed actual value of the decision parameter is within the predefined test range, or the maximum time interval between two successive tests of the technical component has elapsed.
摘要:
A method for operating a wind turbine during a loss of communication is described that includes coupling a pitch controller to at least one wind turbine blade and to a wind turbine controller, establishing communication between the pitch controller and the wind turbine controller, and detecting a loss of communication between the pitch controller and the wind turbine controller. After a loss of communication is detected, the method further includes waiting for a first predetermined amount of time to elapse, independently pitching the at least one wind turbine blade to a predetermined position, waiting for a second predetermined amount of time to elapse, and maintaining the at least one wind turbine blade in the predetermined position until a rotation of the at least one wind turbine blade stops.

摘要:
A nacelle for a wind turbine includes a shell having an exterior surface and an interior surface that defines an inner cavity. The nacelle includes an insulative covering that is positioned adjacent to the exterior surface. The insulative covering is configured to reduce a fluctuation of a temperature within the inner cavity.
