Abstract
A method and a system for generating auxiliary power for an islanded wind turbine are described, wherein the wind turbine may comprise a generator configured to provide power to a main grid. The method comprises: detecting an island mode of operation wherein said wind turbine is electrically disconnected from said main grid; in response to said disconnection, adjusting the rotational speed of said wind turbine to a value within a range of low rotational speeds; converting said generator output to a value suitable for charging said auxiliary power distribution system; and, connecting the output of said converter to said auxiliary power distribution system.
