Abstract

A method for controlling the operation of a wind turbine (120) comprises (a) receiving an active power reference signal (P*conv, PrefWT) being indicative for active power to be generated by the wind turbine (120) and an active power feedback signal (Pfb) indicative for active power generated by the wind turbine (120); (b) determining, based on the active power reference signal and the active power feedback signal, a first voltage control signal (Vd) and a power controller frequency signal ( É PC); (c) receiving a power reference signal (Pumb*) indicative for a desired power flow through an AC auxiliary power transmission system (164) and a power feedback signal (Pumbfb) indicative for the actual power flowing via the AC auxiliary power transmission system; (d) determining, based on the power reference signal and the power feedback signal, a power offset frequency signal ( É uPC) indicative for an actual power offset within the AC auxiliary power transmission system; (e) determining, based on the power controller frequency signal ( É PC), a second voltage control signal (Vq); (f) determining, based on the power offset frequency signal, an angle signal (¸0) indicative for an actual angle of a rotating dq reference frame; and (g) controlling the operation of a power converter (240) based on the first voltage control signal, the second voltage control signal, and the angle signal. It is further described a network bridge controller, a wind turbine, a power generating and forwarding system, and a computer program which are all capable of carrying out or controlling the described control method.
