Synchronization of Distributed Photovoltaic Generation with an Active network using Phase Locked Loop technique

摘要

The above paper gives the detail design of Solar PV system along with its synchronization with grid connected systems. In this paper detailed design of system along with the design of boost converter, design of inverter system for 180 degree conduction mode along with its SPWM technique and grid synchronization using Phase locked loop technique has been discussed. The PV panel's DC output is amplified by using boost converter up to desired value. which is further converter into A.C. supply by using 3-phase inverter which is working under 180 degree conduction mode which can be controlled by Sinewave pulse width modulation techniques. The reference signal for the system is derived by the grid using phase locked loop so the output of the inverter is in synchronism with grid with respect to phase as well as frequency.
