Abstract:

Accurate fault location technique minimizes the power outage time and operating costs. This talk will first briefly introduce the classification of transmission line fault location methods. Then the way to find the voltage distribution over transmission line with traditional Bergeron method is introduced. Afterwards, this talk will introduce the proposed 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.
