A METHOD FOR OPERATING A WIND TURBINE, AND A POWER PLANT

A method (1000-1001) for operating a wind turbine (100) including a rotor (106) having rotor blades (108) and a power conversion system (118, 210, 234) mechanically connected with the rotor (106), configured to convert input motive power into electrical output power, and electrically connected to a...

More Information
Summary:A method (1000-1001) for operating a wind turbine (100) including a rotor (106) having rotor blades (108) and a power conversion system (118, 210, 234) mechanically connected with the rotor (106), configured to convert input motive power into electrical output power, and electrically connected to a network (242) for feeding the electrical output power (P) to the network is provided. The method includes determining (1100) a current frequency (f) of the network (242), and, when the current frequency (f) is equal to or lower than a threshold frequency (fthresh), operating (1300) the power conversion system (118, 210, 234) at an electrical output power (P) which is increased by an electrical output power increase (PI) in accordance with a monotonic function (PI(f)) of the current frequency (f) limited to a maximum value (PImax).
