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 (S s ) is generated by means of at least one Phase-Locked Loop (4) from a main electrical signal (S e ) received from the electrical power system. The Phase-Locked Loop (4) comprises a controller scheme with a plurality of gain parameters (K mn ) to eliminate at least some of the deviations of the synchronization signal (S s ) in respect of the main electrical signal (S e ), and said gain parameters (K mn ) are adjusted depending on the frequency and the amplitude of said main electrical signal (S e ).
