Abstract: The invention relates to a power management system for one or more wind turbines where the one or more wind turbines are connected to a power supply with a limited capacity for providing power to a number of power consuming units, such as to an emergency power supply arranged for providing power in a grid loss situation. The power management system comprises a dispatcher connected to the power supply to access an available capacity of the power supply, and a requester connected to at least one power consuming unit, the requester being arranged to control the power consumption of the power consuming unit by either allows or deny the power consuming unit to consume power.

Abstract: A power management module and method for controlling power consumption of consumers in a wind turbine system. Each power management module in the wind turbine system is configured to determine a voltage level of a power supply bus of the wind turbine system and then control a level of power consumption of one or more consumers coupled to the power supply bus based at least in part on the determined voltage level of the power supply bus. Power consumption may thereby be managed throughout the wind turbine system, without requiring a dedicated centralised controller and communications infrastructure.

Abstract: A method, controller, wind turbine, and computer program product are disclosed for collecting data from wind turbines in a wind farm. An example method generally includes receiving, from a client device, a subscription request identifying a plurality of data points to collect from a set of wind turbines. A wind farm server establishes a client interface with the client device. The wind farm server receives data points form the plurality of wind turbines and buffers the identified collected data points from the set of wind turbines in a data repository. Through the client interface, the wind farm server receives a request for data points collected from at least one wind turbine over a specified time period, and responsive to the request, transmits the requested data points to the client device. The wind farm server also may push collected data points from wind turbines to a data analysis system.

Abstract: The present invention relates to a wind turbine comprising an internal power supply grid for distributing power to a number of power consuming units of the wind turbine, the wind turbine further comprising a power backup system connected to the internal power supply grid for supplying power to said internal power supply grid during a grid fault, wherein the power backup system comprises a power storage module providing a total backup voltage that falls within a nominal voltage range of the internal power supply grid of the wind turbine.
