UK HVDC centre demonstrates grid monitoring devices

UK: The National HVDC Centre in the UK has tested two devices that monitor and detect faults in DC multi-terminal grids and aims for a public demonstration next year.

Testing and development of the intelligent electronic devices has been carried out under the auspices of the Progress on Meshed HVDC Offshore Transmission Networks (Promotion) initiative.

One of the monitoring devices was developed in work package four of Promotion, while the other was provided by Mitsubishi Electric Europe.

The devices aim to overcome the challenge of how to protect multi-terminal grids in the event of a fault so that only the faulty components are isolated rather than the whole grid.
