Variable speed wind turbine, a resonant control system, a method of operating a variable speed wind turbine, use of a resonant control system and use of a method in a variable speed wind turbine
Variable speed wind turbine, a resonant control system, a method of operating a variable speed wind turbine, use of a resonant control system and use of a method in a variable speed wind turbine
A variable speed wind turbine connected to a utility grid includes a rotor, having at least one blade, a drive train connected to the rotor, the drive train includes a selection of at least one gear box, and at least one electrical generator, a measuring arrangement establishing at least one rotational speed signal of the drive train, and at least one wind turbine power controller connected to the at least one generator and the utility grid. Furthermore the wind turbine includes at least one resonant controller modifying a power reference value in response to the at least one rotational speed signal. A resonant control system, a method of operating a variable speed wind turbine, use of resonant control system and use of a method in a variable speed wind turbine are also contemplated.
