Detection of power quality disturbances using symbolic dynamics

Detection of Power quality (PQ) disturbances has become imperative for utilities as well as for consumers due to huge cost encumbrance of poor power quality and increased sensitivity of electronic equipments towards power quality. It is the first step towards monitoring and analysis of PQ disturbances. This paper proposes a simple and novel method based on symbolic dynamics for detection of PQ disturbances. The proposed method is applied to the synthetic data of PQ disturbances and 100% accurate results are obtained.
