Abstract
—A passive islanding-detection technique is proposed in this article for a distribution network with a distributed generation system including a doubly fed induction generator. This method is based on the processing of the measured voltage signals of the distributed generation connecting bus using discrete wavelet transform. Different types of disturbances including faults (single-phase, two-phase, and three-phase) and power quality disturbances (capacitor switching, load switching, and motor starting) are used to discriminate from islanding conditions. A wind turbine equipped with a doubly fed induction generator is considered as the distributed generation source in an unbalanced distribution system. The studied system is simulated with high level of detail in PSCAD/EMTDC software for the purpose of this work. The results of implementing the proposed method verify the high accuracy, reliability, and speed of the proposed islanding-detection approach even with small non-detection zone and the presence of high levels of noise in measured voltage signals.
