HVDC cable modelling for VSC-HVDC applications
2014 IEEE PES General Meeting | Conference & Exposition, 2014This paper assesses the impact of commonly used cable modelling techniques on the accuracy and simulation speed of detailed VSC-HVDC models for a range of typical studies. The results show that the choice of cable model can have a significant impact on the accuracy of the VSC-HVDC models and that employing a higher fidelity cable model does not ...

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.
