DC faults in HVDC: Detection, identification, and handling

Sammendrag

In the last decade, multiterminal HVDC (MTDC) systems have gained much attention as they represent the most economically effective solution to transfer bulk power over long distances. MTDC systems are HVDCs that consist of three or more terminals. This solution suits certain applications such as the large-scale integration of remote renewable sources and the interconnection of asynchronous AC regions.

One of the most desirable features of meshed MTDC systems is the ability to increase the reliability of power transfer; for example, when a DC fault occurs in an MTDC system, there is a rapid fault propagation to the rest of the system, and the power transfer could be interrupted if measures are not taken. To provide alternative transmission paths, a proper overall protection system must be designed. Therefore the protection system for MTDC plays a fundamental role to minimize the impact of DC faults and warrants reliable power transfer in MTDC systems.
