An Improved Method for Fault Analysis in Asymmetrical High Voltage Direct Current Transmission Lines
2019 International Conference on Electrical, Electronics and Computer Engineering (UPCON), 2019In this paper a simple technique using wavelet for asymmetrical HVDC lines is studied. Wavelet analysis is carried out using various wavelets to different levels and one suitable wavelet is chosen as mother wavelet. Approximate coefficients are selected and standard deviations of approximate coefficients are used as input.

A fault location method based on genetic algorithm for high‐voltage direct current transmission line
European Transactions on Electrical Power, 2012SUMMARYA fault location method based on genetic algorithm for high‐voltage direct current (HVDC) transmission line is proposed in this article. This method adopts the Bergeron model of transmission line, in which the voltage at any point of the line can be calculated by the voltage and current data sampled at both terminals of the line, and the fault ...

With the construction of ultra-high-voltage direct current (UHVDC) transmission lines, the complex electromagnetic environment around the lines has been a widespread concern. The ZigBee-based field measurement system is widely used in ground space charge density measurements of HVDC transmission projects.

Analysis of Lightning-attractive Areas Around High-voltage Direct Current Transmission Line
Electric Power Components and Systems, 2009Abstract This article studies attractive areas around high-voltage direct current transmission lines due to downward lightning leader presence. The lightning-attractive areas are drawn for power conductors and shielding wires separately to distinguish the shielding failure area.

Corona discharge is a common phenomenon in high voltage direct current (HVDC) transmission lines. It generates ion flow and space charge in the air. Electric field under HVDC transmission lines is enlarged. Based on the Kaptzov assumption, electric field is calculated by the upstream finite element method.
