Abstract
Customer demands better power quality and reliability. Distributed generation (DG) is widely used due to
environmental worries to fulfill additional power requirement. Islanding detection is an important
requirement for distributed generation. Several problems are caused, when DG fails to trip at islanding
condition. It gives negative impact to the loads and generators. When islanding has occurred, distributed
generator must be disconnected as soon as possible. Thus, distributed generator must be equipped with
islanding detecting devices like over/under voltage relay, impedance relay, etc. They give trip signals to DGs
when islanding is found. In this paper, one case study is analysed with different methods such as voltage
measurement, impedance measurement, total harmonic distortion (THD), and negative sequence component.
The case study is verified for detecting islanding under different loading condition such as normal condition,
islanding situation, and isolation of other DG.
