Abstract

Large offshore wind farms located far from shore, as are being planned or built in the North Sea, will require high-voltage DC (HVDC) transmission to shore, and multi-terminal HVDC could offer further benefits. Currently proposed methods to protect against faults in the DC network are based on extremely fast-acting DC circuit breakers located on all cable ends, leading to high cost. A method is proposed based around discharging the DC network to isolate the fault, which drastically reduces the circuit breaker requirement, while making use of the inherent current-limiting behaviour of the wind turbines. The validity of this approach is demonstrated in simulation.
