Abstract

Islanding detection and protection is an important aspect in grid connected solar photovoltaic power generation system. This paper presents the analysis, design, implementation and evaluation of passive anti-islanding methods in solar PV plants. Over/Under Voltage Protection (OVP/UVP) and Over/Under Frequency Protection (OFP/UFP) are basic passive islanding detection method (IDM) for detecting an islanding condition by monitoring parameters at Point of Common Coupling (PCC) such as voltage amplitude and frequency and then cause the inverter to shut down when there is sufficient transition from normal specified threshold range. The performance of the proposed method has been studied by using simulations in MATLAB/SIMULINK.
