Hybrid HVDC circuit breaker with self-powered gate drivesTools Effah, Francis Boafo and Watson, Alan James and Ji, Chao and Amankwah, Emmanuel K. and Johnson, Christopher Mark and Davidson, Colin and Clare, Jon C. (2016) Hybrid HVDC circuit breaker with self-powered gate drives. IET Power Electronics, 9 (2). pp. 228-236. ISSN 1755-4543 Full text not available from this repository.AbstractThe ever increasing electric power demand and the advent of renewable energy sources have revived the interest in high-voltage direct current (HVDC) multi-terminal networks. However, the absence of a suitable circuit breaker or fault tolerant VSC station topologies with the required characteristics (such as operating speed) have, until recently, been an obstacle in the development of large scale multi-terminal networks for HVDC. This paper presents a hybrid HVDC circuit breaker concept which is capable of meeting the requirements of HVDC networks. Simulation results are presented which are validated by experimental results taken from a 2.5kV, 700A rated laboratory prototype.
