The occurrence of various faults in the transmission lines is inevitable due to the power transmission lines' complexity and length. Detecting, classifying, and locating faults in these systems can prevent further damage to the power grid. Algorithms based on the traveling wave theory are often implemented based on signal processing methods and can determine only the location of the faults. Determining the type of fault due to the wide variety of possible faults in the transmission lines can help the protection system operate more reliably and faster. Accordingly, in this paper, an integrated fault detection, classification, and location model is proposed, which uses only the voltage signals measured on one terminal of the transmission line. In order to extract features from the primary signal, Gabor wavelet transformation is used and its results will be utilized for fault detection and classification. Next, the traveling wave concept is applied to determine the fault section and estimate its location. In addition, due to the installation of the reactive power compensator in the transmission line, the performance of the protection system must be updated. Simulation results in MATLAB demonstrate the accurate performance of the proposed model in fault detection, classification, and location. By employing the proposed strategy, the average accuracy of fault classification and location is 100% and 99.573%, respectively. |
