HVDC Transmission Line Faults Analysis
An electrode line is used in some high-voltage direct-current HVDC power transmission systems, to connect the converter stations to distant ground electrodes. Many long-distance HVDC systems use sea or ground return for the DC neutral current since this is considerably cheaper than providing a dedicated metallic return conductor on an overhead wire or cable. The ground electrode is separated from the converter station so that current returning through the ground electrode does not cause corrosion of parts of the station in contact with the earth. The connection into the ground requires a specially designed ground electrode or earth electrode. The electrode line can be implemented, depending upon the situation of the electrode onshore or in the sea , as ground cables, as overhead line, or as a combination of ground cable and overhead line. In the event that one of the poles in the bipolar system is faulted, the current path will switch to ground return, thus allowing the system to continue operating at reduced capacity and reducing the possibility that a pole fault will cause a bipolar outage.

Abstract Todays world relies mostly on the utilization of electrical energy for industrial, commercial, agricultural, domestic and social purposes. However, for the present HVDC system, proper protection instruments and logic are not yet much developed as the AC system. Faults occurring in the DC transmission line are analyzed. This paper also looks into the response of the system to different kind of faults. It is seen that the AC and DC faults have different characteristics allowing us to differentiate them apart.

In addition, the controllability of power flows in the power grid has added a new dimension to the use of HVDC links in the context of developing Smart Grids. The power transfer from off-shore wind generation is another new application. This second edition is a complete revision of the first edition taking into account the developments that have taken place since the first edition was published. Instead of adding new chapters to present the new developments, the new material is added at the appropriate places.

Current advances in technology offer project promoters many opportunities to implement new solutions to cope with future network development, which is defined in the TYNDP. Together with current technologies, innovative technologies will be incorporated with the existing infrastructure. These technologies have their own learning curves and innovation cycles.
UoM administered thesis : Phd. Authors: Li Shen. Abstract The development of voltage source converter VSC based high voltage direct current HVDC transmission has progressed rapidly worldwide over the past few years. The UK transmission system is going through a radical change in the energy landscape which requires a number of VSC HVDC installations to connect large Round 3 windfarms and for interconnections to other countries. For bulk power long distance transmission, VSC HVDC technology offers flexibility and controllability in power flow, which can benefit and strengthen the conventional AC system. However, the associated uncertainties and potential problems need to be identified and addressed.
