A influência do Sinal de Ripple Control na Operação de Relés de Proteção a Distância

Abstract

This study aims to analyze the impact generated by Ripple Control on distance protection relays, since this load management technique has been widely used in European continent. The motivation for this study is due to the fact that this method is responsible for promoting a considerable interharmonic distortion in the electric power transmission lines, compromising the voltage and current signals of the system, which can trigger failures in the operation of these protection devices. In this work, situations similar to those faced by the power networks are simulated and an investigation is carried out regarding the location of the fault provided by the distance relay. In addition, it is worth mentioning that the entire project was developed in the laboratory and the conclusions were obtained based on the results made available by the equipment’s and software’s used.
