Ubicación de fallas eléctricas en líneas de transmisión basado en el filtro de Kalman

Abstract

In the present work a methodology is approached that allows to locate and classify the different types of electrical faults that can be generated in a transmission line, for this a Kalman filter algorithm is carried out which is based on the analysis of the signals of current and voltage obtained from the EMPT simulator in which several scenarios with symmetric and asymmetric failures in the transmission lines of the SEP were proposed. The problem is focused on locating electrical faults in the transmission lines of the IEEE 9-bar system and the results obtained are taken to the Kalman filter algorithm that has been developed in Matlab, which is based on performing a set of recursive processes with the voltage and current signals that feed the filter and thus allow to visualize a hidden state of a process, which for the case is to locate electrical faults. This is a method that does not require prior knowledge or approximation of the type of failure since the filter is characterized by being an estimator and therefore is made up of a predictive and corrective part. The results obtained have been verified by generating various fault scenarios with the EMPT simulator, validating the efficiency and precision of the proposed method based on the Kalman filter for the identification of electrical faults.
