An Effective Index for Islanding Detection Based on Fast Discrete S-Transform [PDF]
Advances in Electrical and Electronic Engineering, 2019 Passive methods of islanding detection have the advantage of not perturbing the system, but they suffer from large Non-Detection Zone (NDZ) and unpredictable detection time. In this paper, a new passive scheme for islanding detection, based on estimating
