There has been much discussion over how HVDC grids incorporating many converters should be controlled and several methodologies have been proposed. An underlying principle of a proposed method, Voltage Droop control, was the minimisation of the inter-dependency of the control of the individual converters, inferring little, or no, reliance on a communication system. Since then further work has shown...
In future HVDC grids, or ‘Supergrids’, high voltage DC circuit breakers will almost certainly be used in order to remove a faulted element of the HVDC Grid whilst allowing power flow to continue on the remaining grid. However, associated with these HVDC circuit breakers will be the need for a means of fast fault detection, location and isolation. This paper presents a none-conventional approach to...
