Fault-Type Discrimination in HVDC Transmission Lines Using Rate of Change of Local Currents
IEEE Transactions on Power Delivery, 2020A simple and yet dependable technique for fault-type identification in HVDC transmission systems is presented in this paper. A set of indices is defined for pairs of rate of change of current measurements to identify the pole(s) involved in the fault to ...

Shielding Effect of HVAC Transmission Lines on the Ion-Flow Field of HVDC Transmission Lines
IEEE Transactions on Power Delivery, 2013The HVDC and HVAC transmission lines running on the same tower is a promising technology to improve the transmission capacity of an existing corridor. The ions generated by corona discharge of HVDC transmission lines will strengthen the ground-level electric field, which may endanger human exposure.

A Novel Fault-Location Method for HVDC Transmission Lines
IEEE Transactions on Power Delivery, 2010This paper presents a method for locating faults on HVDC transmission lines using two terminal data. Different from those based on the traveling wave principle, the new fault-location algorithm can use any section of the postfault data to locate faults.
