A method of controlling a wind turbine is provided including a generator system, an energy storage system and auxiliary equipment, the method including, in particular during a low wind condition: controlling the generator system in order to provide power from the generator system to the auxiliary equipment, in particular such that a rotor speed does not decrease; controlling the energy storage system in order to provide power from the energy storage system to the auxiliary equipment, if required to meet a power requirement of the auxiliary equipment; in particular keeping the wind turbine in operation.

Low-wind ride-through of a wind turbine

A method for starting up a wind turbine for generating electrical power is provided, wherein ice accretion is on at least one blade of a rotor of the wind turbine and wherein the at least one blade has a variable pitch angle, the method including measuring the rotational speed of the electromechanical transducer, calculating a pitch angle adjustment with the goal of maximizing the rotational speed, modifying the pitch angle in a positive or negative step according to the pitch angle adjustment, iterate the preceding steps.

Method for starting up a wind turbine

A method of charging an energy storage system of a wind turbine is provided. The wind turbine includes a power generation system and a power delivery interface. The method includes obtaining a maximum power limit to which electrical power supplied to the external system via the power delivery interface is limited; monitoring an amount of electrical power provided from the power generation system to the power delivery interface or an amount of power generatable by the power generation system; and determining if a predefined condition is met. If the predefined condition is met, the wind turbine is operated in a charging mode in which electrical power generated in addition to a first amount of electrical power is supplied from the power generation system to the energy storage system to charge the energy storage system. The first amount corresponds to a power rating of the wind turbine.

Charging of an energy storage system of a wind turbine

Provided is a method of monitoring the structural integrity of a supporting structure of a wind turbine, which method includes the steps of determining a fore-aft tower oscillation frequency; determining a side-to-side tower oscillation frequency; computing a working structural indicator value from the fore-aft tower oscillation frequency and the side-to-side tower oscillation frequency; comparing the working structural indicator value to a reference working structural indicator value; and issuing an alarm if the difference between the working structural indicator value and the reference structural indicator value exceeds a predefined threshold. Also provided is a system for monitoring the structural integrity of a supporting structure of a wind turbine, a wind turbine, and a computer program product for carrying out the steps of the inventive method.
