HVDC circuit breakers for HVDC grid applications
11th IET International Conference on AC and DC Power Transmission, 2015High Voltage Direct Current (HVDC) transmission has been expanding due to rapid development of power electronics technology and by the need for connection of offshore/remote wind farms and large hydro power generators. An HVDC grid will be required to operate the healthy lines continuously, even if a voltage collapse occurs at the remote end.

Research on Power Modulation Strategy for MMC-HVDC and LCC-HVDC in Parallel HVDC System
2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019Due to the difference between MMC-HVDC and LCC-HVDC control characteristics and the mutual influence of parallel connection, its power modulation strategy is different from that of LCC-HVDC. Coordinated control strategy of parallel system of MMC-HVDC and LCC-HVDC is analyzed.

Damping of Subsynchronous Oscillations by an HVDC Link. An HVDC Simulator Study
IEEE Power Engineering Review, 1981Subsynchronous oscillations in power systems with series compensated lines can be amplified and sustained due to interaction between the electrical power system and the turbine generator mechanical system. Recently it has been found that also an HVDC link may have a similar effect especially when connected near a turbine generator as the only load.

Prediction of Reliability and Availability of HVDC Valve and HVDC Terminal
IEEE Transactions on Power Apparatus and Systems, 1970An availability and a reliability prediction has been made for a high-voltage direct-current (HVDC) terminal containing silicon controlled rectifiers (SCRs). This prediction was made using published failure rates for the electronic equipment. Published failure rates and outage duration times were used for such ac equipment as power transformers and ...

HVDC line protection for the proposed future HVDC systems
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005The paper reviews the ability of present protection systems to provide adequate protection for proposed future HVDC systems. This initial study reviews current protection systems used for DC line protection and highlights both the advantages and disadvantages of these systems including the factors that adversely influence their performance.

Advances in HVDC Technology as applied to the Pacific HVDC Intertie
2008 IEEE/PES Transmission and Distribution Conference and Exposition, 2008The development of the Pacific HVDC Intertie (PDCI) is traced from inception in the 1960s to present day. The PDCI has undergone a number of changes and upgrades over the 36 years since its construction. The changes in the PDCI mirror the advances in HVDC technology over that period.
