Abstract

Recent developments in DC circuit breakers and VSC (Voltage Source Converter) technology mean that multi- terminal HVDC is becoming increasingly technically and economically feasible. HVDC allows electric power to be transmitled over large distances with relatively fewer losses and without the stability problems of HVAC (High Voltage Alternate Current). Multi-terminal HVDC has often been proposed as a possibility for a European super-grid or connecting a large number of offshore wind farms, and has similar applications in large countries such as Brazil, which has significant hydro-resources away from centres of population. In conventional HVDC point-to-point links, the circuit breakers reside on the AC side, and in the event of fault, the entire link is de-energised. In the multi- terminal case however, it is more desirable to isolate only the faulted link rather than trip the entire DC grid. Not only does this require DC breakers, but also a DC protection relay that will discern when to operate the breakers. This project will investigate the feasibility of novel methods for DC protection relays, particularly combining the use of high frequency post fault information and AI inference engines such as Neural Networks and Fuzzy systems.
