FAULT ANALYSIS ON THREE PHASE THREE LEVEL SVPWM BASED GRID CONNECTED PHOTOVOLTAIC SYSTEM

Solar energy has become a major source of energy with the advancements in pv cell efficiency and reduction in cell cost; grid-connected photovoltaic (PV) systems does not require bulk and lossy battery bank. High voltage Distributed generation and on-site supply of PV system reduces distribution losses, and mitigates environment pollution. This paper presents a Dynamic model of grid-connected PV system using Matlab/Simulink. Based on the accurate system modeling, optimum control and fault analysis are studied. The simulation studies verify the effectiveness of the proposed system, and demonstrate that the proposed control system has good static as well as dynamic performance.
