This paper proposes an intelligent fault locating method using a new signal analysis technique called Empirical Mode Decomposition (EMD) and Core Vector Regression (CVR) for large distribution systems. The conventional fault locators are based on the measurement of post-fault line impedance suffering from the factors such as path fault impedance, system configuration and line loading, so that they have low accuracy. On the other hand, because of the vast range of resistances, the negative impact of damping factors affects the performance of travelling wave-based fault locators in large distribution systems. To overcome these problems, this paper uses a minimum measuring …
