Abstract The control of three-phase grid-tied converters needs accurate detection of the grid synchronization signal. For the frequency-locked loop based synchronization signal detection method, the paper analyzes dynamic performance of DSOGI-FLL under the grid voltage unbalance. The frequency-locked loop is linearized and simplified as a first order system through average theory. The results show that the dynamic performance of frequency-locked loop is associated with the voltage magnitudes of the positive sequence component, and the negative sequence component. The paper proposes a normalized frequency adaptive method of frequency-locked loop. Compared with the currently used methods, the proposed wethod has good response, and can acquire accurate magnitude and phase information of the positive sequence and negative sequence components. The simulation and experiment results verity the validation of the proposed normalized method.

Key words： Synchronization signal frequency-locked loop amplitude dynamic response nor- malization
