Wind turbine with control means to manage power during grid faults

摘要

The present invention relates to a method for operating a wind turbine facility during for example a grid fault, the wind turbine facility comprising power dissipation/storage means being adapted to dissipate or store electrical energy exceeding an amount to be delivered to an associated power supply grid during the grid fault, the method comprising the step of operating the wind turbine facility in accordance with an allowed amount of electrical energy that can be dissipated or stored in the power dissipation/storage means of the wind turbine facility by ensuring that a total amount of electrical energy generated by the wind turbine facility does not exceed a sum of the allowed amount and the amount to be delivered to the power supply grid.
