Abstract

Islanding occurs when a Distributed Generation (DG) source continues to energize an isolated section of a power system even after it is disconnected from the main power grid. This paper proposes an Islanding detection method for Grid Connected SVPWM three phase inverter. Whose DC voltage is taken from Photo Voltaic (PV) source with MPPT controlled Buck-Boost Converter. Solar Panel helps to sense both voltage and power ratings and uses MPPT Perturb and Observe method for voltage control and regulation by operating both power and current as variables. A Passive islanding detection using ROCOF method is used such that the oscillations in rate of change of frequency are measured at the Point of Common Coupling (PCC) in the system. Simulation work is used to verify the outputs. The software used is MATLAB.
