Study and Simulation of SOGI PLL for Single Phase Grid Connected System

Authors(2) :-Radhika Urhekar, S. U. Kulkarni

Algorithms for synchronization of grid are highly important in control of grid interfaced power converter. In order to execute stout control strategies for the interconnection of renewable energy systems with grid, rapid and precise detection of grid parameters such as amplitude, phase and frequency is critical. This paper propounds Phase Lock Loop technique for grid synchronization of single phase Distributed Generation System. Second Order Generalized Integrator (SOGI) PLL serves as Quadrature Signal Generator (QSG) which revolves around SOGI ,Parks Transform, Low pass filter (LF) and frequency phase shift generator (FPG). The QSG-SOGI and Parks Transform system is used for enhancing the performance of prevalent multiplier based phase detector (PD). Model of SOGI-PLL in MATLAB/Simulink environment is shown here.
