Beschreibung
Zusammenfassung:► A Teager Energy Operator algorithm is proposed to detect and analyze power quality events. ► In order to detect a disturbance, magnitudes of the signal are calculated using TEO algorithm. ► Proposed method has a simple and faster algorithm and it is robust in detecting PQ disturbances. ► We compare the TEO with the methods used previously in PQ detection, these are not adequately faster. ► The proposed approach with a faster response time is more suitable for real time applications. In this paper, a novel algorithm, based on the Teager Energy Operator (TEO) of a sinusoidal waveform, proposed to detect and analyze the voltage disturbances. Most common power quality (PQ) disturbances at the distribution level such as voltage sags, notches, and capacitor switching are presented. These examples provide the basis for further characterization of other power quality events. Magnitudes of transient PQ events are located in the width of the signal. Furthermore, meaningful components of transients are analyzed. The whole method is implemented and tested over a sample representing recorded disturbances. Simulation and experimental results of different PQ disturbances show that the proposed method is fast and robust in detecting voltage disturbances and requires only a few samples to calculate the energy of a signal.
