Abstract

See full text

Methods of operating a wind turbine (1) having a generator (10) and a power converter (60). The methods may comprise: determining a reduced first power setpoint (94) in response to an operational condition; reducing active power from a line-side converter (66) to an electrical grid (80) according to the reduced first power setpoint (94); determining a reduced power setpoint (92) for a machine-side converter (62); reducing a torque applied to the generator (10) by the machine-side converter (62) such that active power according to the reduced second power setpoint (92) is produced by the generator (10); and dissipating a power surplus in one or more resistive elements (68) as long as the second power setpoint is superior to the first power setpoint. Wind turbines configured for such methods are also provided.
