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).
