Abstract

The phase angle utility is a critical piece of information for operation of power devices feeding power into the grid like PV inverter.A Phase Locked Loop (PLL) is a closed loop system in which an internal oscillator is controlled to keep the time/phase of an external periodical signal using a feedback loop.In this paper,a method is proposed to enhance the performance of a phase locked loop.An adaptive notch filter is used to selectively notch the exact frequency.Simulation of both the basic PLL and the improved PLL are made by MATLAB/Simulink,the result is summarized in the last section.
