SuperGrid Institute’s DC circuit breaker goes public
at the IEEE General Meeting in Denver
We are thrilled to be participating in the IEEE Power & Energy Society General Meeting in Denver, Colorado from the 17th – 21st July 2022. This conference, that brings together leading power engineers and key academics from all over the world, offers the perfect platform for us to present our latest advances on our modular DC circuit-breaker for MV and HV applications.
We are proud to be revealing our 525kV DC circuit breaker at the IEEE Power & Energy Society General Meeting. The breaker is adapted for both non-selective & selective protection strategies thanks to its very low reaction time. This technology combines reliable interruption, even at small currents, with a large range of short circuit currents. By stacking its modular units this innovative solution can also be adapted to network voltages ranging from medium voltage to the highest transmission voltages.
The DC circuit breaker is a critical element for enabling the operation of meshed DC networks. We have recently made a major step forward by confirming the performance of our design via in-house power tests, at medium & high voltages and have also just finished a series of mechanical endurance tests which produced very encouraging results, confirming that our confidence in this solution is well placed. We are now ready to present our solution to other industry players and support them in the integration of this technology into future energy networks.

Speaking in a Panel Session:
Towards interoperability in VSC-HVDC Networks
Another of our engineers, Sebastien Silvant, HVDC Interoperability Project Manager, is taking part in a second panel session where he will present his take on how to make HVDC grids modular and interoperable. In his talk, he will discuss the steps that can be taken to achieve interoperability by design: agreeing on a common functional framework for multi-terminal HVDC control and protection systems, splitting the functional scope between subsystems & defining the resulting standard interfaces, and eventually issuing functional specifications that are as open as possible and as precise as necessary. Only a joint effort between industrial stakeholders will make it possible to reach the necessary consensus. HVDC interoperability will unlock multi-vendor HVDC grids and impact further transition of the energy sector at a large scale.
