Design of Phase Locked Loop Based on Second Order Generalized Integrator for Unbalanced Three-phase Voltage
摘要
Abstract
In order to solve the active power filte(r APF)control requirements in the three-phase voltage unbalance,the amplitude,frequency and phase information about fundamental positive sequence component of grid voltage are obtained quickly and accurately is critical. For this problem,a method named second order generalized integrator phaselocked loop(SOGI- PLL)of adaptive frequency performance characteristics which could achieve a positive sequence component information extraction was proposed. The simulation and experimental results show that the proposed method can quickly and accurately extract the amplitude,frequency and phase information about positive sequence component of grid voltage in three-phase voltage unbalance,and has good performance in adaptability of frequency.关键词
