Sequential auto-reclosing method for hybrid HVDC breaker in VSC HVDC links
2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016Voltage source converters (VSC) are increasingly being used in high voltage direct current (HVDC) systems and with higher power ratings of these converters, the interest for usage with long transmission system is also increasing. With long overhead transmission dc links, many faults would be transient or temporary in nature.

Fullbridge MMC control for hybrid HVDC systems
2017 Brazilian Power Electronics Conference (COBEP), 2017The Fullbridge based Modular Multilevel Converter (FBMMC) has been widely considered as one of the best solutions for High Voltage Direct Current (HVDC) systems, especially due to its capability of limiting dc short-circuit currents. Generally, the use of FBMMC on hybrid HVDC configurations with Line Commutated Converters (LCC) is considered for ...

Hybrid HVDC system for multi-infeed applications
2013 International Conference on Emerging Trends in Communication, Control, Signal Processing and Computing Applications (C2SPCA), 2013The application of HVDC for stabilizing the large interconnected AC networks are resulting in several HVDC links inverting in the close electrical proximity. These multi-infeed HVDC system inverting into a weak AC network are of serious concern. One of the possible solution for better stability is using a VSC-HVDC as one of the infeed for the multi ...
