INTRODUCTION OF ISLANDING, ISLANDING DETECTION METHOD AND DISTRIBUTED GENERATION

In increasing development of world, the “electricity or electrical power” plays main role. For this delivering the continuous power is necessary. In this paper we will discuss about situation of islanding in which local load disconnected from main grid or micro grid and connected with source of distributed power generation. Distributed generations like PV cells, wind turbines etc. gives the continuous power supply to the load and protect it from the interruption. When load disconnected from grid and connect with DG set, for this some islanding detection methods are used which is active method, passive method and utility based method
