Three Phase Transmission Line Fault Location Based on the Generalized Bergeron Model

Accurate fault location technique minimizes the power outage time and operating costs. This paper proposed a three phase transmission line fault location scheme based on the generalized Bergeron model. Three phase instantaneous voltage and current measurements at two terminals of the line are required. Compared to traditional Bergeron model based fault location scheme, the proposed method does not need the assumption of geometrically symmetric transmission lines and works for arbitrary transmission line parameters. Numerical experiments demonstrate that the proposed generalized Bergeron model based method has higher accuracy compared to the traditional Bergeron model based method.
