The colloquium of the Center for Advanced Power and Energy Systems (CAPES) was held on May 15, 2019. This is a monthly event where we invite students and experts in the area of power and energy to give presentations about their research.

Today the presenter is Mr. Dayou Lu from PSPAL. He gave a talk on his research: Three Phase Transmission Line Fault Location Based on the Generalized Bergeron Model. After the presentation, the audience discussed with the presenter about the details of his research.

Dayou Lu was born in Hunan, China. He received the B. S. degree in the School of Electrical and Electronic Engineering, Huazhong University of Science and Technology, Wuhan, China. He is currently working toward the M. S. degree in the School of Information Science and Technology, ShanghaiTech University, Shanghai, China. His research interests include the transmission line modeling and fault location.

The abstract of this talk is as follows. 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.
