Effect of dg location on multi-parameter passive islanding detection methods

Passive islanding detection methods are considered the simplest and cheapest approach for detecting an islanding condition of a Distributed Generator (DG). Passive methods, relying on one system parameter, suffer from large Non- Detection Zones (NDZ). To overcome this problem, new passive methods relying on more than one parameter and their combination have been recently proposed. These methods were tested for a specific DG location. In this paper, an approach is presented to investigate the effect of DG location on the choice of parameters. Consequently, 40 different possible parameters are extracted and ranked based on information gain to determine the most effective and robust parameters for passive islanding detection. This method is tested on synchronous based distributed generation connected to the IEEE 34 bus system.
