HVDC CIRCUIT BREAKER: A REVIEW ON CHALLENGES AND INNOVATIONS

The inevitable shift from fossil fuels to regenerative sources imposes a great challenge for future power transmission scenario. A large and meshed HVDC - Grid is proposed by experts as the best and most efficient solution. And for meshed DC - Grids, the most essential requirements are guarantee for fast and reliable handling of DC - faults without disturbing the energy flow in the whole grid. The following paper presents the key component i.e. DC - Breakers in large meshed HV DC - Grids. This paper aims at summarizing fu nctional analysis of HVDC circuit breakers technologies including recent challenges and attempts in development of improved HVDC circuit breakers. Additionally, different technologies from derived information from literatures are compared. And finally, rec ommendations for improvement of circuit breakers are presented .
