Webb29 okt. 2012 · This project aims at measuring the phase angle between two signals of same frequency. This is incorporated using a Phase Locked Loop (PLL).The PLL used is an analog PLL. Suitable input signals are generated for testing the circuit and are conditioned as demanded by the network and fed into the PLL. WebbAbstract: Grid synchronization algorithm is used to track the fundamental phase angle and frequency of the grid voltages/ currents accurately, to generate the reference currents for control of grid-interactive power converters. Phase-locked loop (PLL) is vital in the grid synchronization technique.
