A Transient Protection Scheme for HVDC Transmission Line
IEEE Transactions on Power Delivery, 2012The relation between the parameters of dc transmission line and the variation of transient energy has been analyzed under various fault conditions in this paper. According to that, a new transient energy protective scheme is proposed. It is developed based on the distributed parameter line model in which the transient energy distribution over the line ...

A novel protection scheme for HVDC transmission line
2011 International Conference on Advanced Power System Automation and Protection, 2011The formation of the transient capacitive current and its effects on the HVDC transmission line differential protection is analyzed based on the wave propagation principle in this paper. The magnitude of capacitive current in the transient process of DC line fault is directly proportional to the time difference of fault signal travelling to both ...

A Fault Location Method for HVDC Transmission Lines
Applied Mechanics and Materials, 2014A fault location method for HVDC (High Voltage Direct Current) transmission lines is proposed in this paper, using voltages and currents measured at two terminals of dc lines in time domain. Fault traveling waves propagate from the fault point to both terminals along the faulted line.

A protection system for long HVDC transmission lines
Proceedings of the Inaugural IEEE PES 2005 Conference and Exposition in Africa, 2006A recent review of the currently used HVDC line protection systems clearly indicated that these systems were not adequately equipped to protect HVDC schemes with extremely long HVDC transmission lines. Therefore, considering the increase in HVDC transmission line lengths projected for the future HVDC schemes, it is of vital importance that some type of

EM Environmental Evaluation of HVDC Transmission Lines
The 2006 4th Asia-Pacific Conference on Environmental Electromagnetics, 2006Due to the high voltage operation of transmission lines, corona discharge phenomena are quite common around AC and DC transmission lines. A large amount of positive and/or negative ions are generated during the corona processes. The effects of corona space charge arising from HVDC transmission lines are much more significant than that in AC ...

The fault location method for HVDC transmission line
2006 China International Conference on Electricity Distribution (CICED 2006), 2006The integrative fault location approach which combines the single terminal, dual terminals traveling wave location method and traditional fault location method has been brought forward. The new approach could fetch up the deficiency of the dual terminals traveling wave location method. The possible unsuccessful case of traveling wave fault location has

Conductor surface voltage gradients on bipolar HVDC transmission lines
IEEE Transactions on Power Apparatus and Systems, 1976The method of successive images is used to obtain accurate values of maximum surface voltage gradients for practical HVdc transmission lines. The results are presented in the form of graphs of gradient factors as a function of the principal line parameters.
