Abstract: Synchronization system and method for a power generation unit coupled to an electrical power system, in order to facilitate the synchronization between the power generation unit and the electrical power system. A synchronization signal (SS) is generated by means of at least one Phase-Locked Loop (4) from a main electrical signal (Se) received from the electrical power system. The Phase-Locked Loop (4) comprises a controller scheme with a plurality of gain parameters (Kmn) to eliminate at least some of the deviations of the synchronization signal (Ss) in respect of the main electrical signal (Se), and said gain parameters (Kmn) are adjusted depending on the frequency and the amplitude of said main electrical signal (Se).

Abstract: A wind turbine that includes a housing, an asynchronous generator disposed in the housing and configured to be electrically connected to a power grid connection; a power converter circuit disposed in the housing and configured to be electrically connected to the asynchronous generator; and a variable impedance device disposed in the housing, connected to the generator and configured to limit current by varying impedance in response to a transient current. The wind turbine delivers reactive power to the power grid when the variable impedance device varies impedance in response to the transient current. The variable impedance device can be arranged in series between the asynchronous generator and the power grid connection, or can be in a shunt arrangement between the asynchronous generator and a neural point.
