Determination and Classification of Unloaded Overhead Line Operating Conditions

What is it about?

Overhead line energization can be performed under normal or faulty conditions. The latter indicates an occurrence of a fault along the line that exists at the moment of energization. This can lead to significant over-voltages that could endanger proper line operation. This paper proposes a novel method that properly detects and classifies line operating conditions at the moment of energization. The method is designed to be useful for utilities and it can be considered as a low-cost, fast, and accurate detection and classification approach.

Why is it important?

In the light of an increasingly high necessity for improving power system reliability and supply quality, it is quite clear how important it is to achieve fast and precise detection and classification of faults that exist during line energization. Significance of the topic, the lack of research in this field, and permanent problems in line fault detection (especially in HIFs detection) in stony areas of Montenegro, have motivated the authors to develop a novel method that detects unloaded overhead line (UOL) energization process under normal conditions, as well the process conducted under faulty conditions.
