Proactive Hybrid HVDC Breakers - A key Innovation for Reliable HVDC Grids

This paper presents a detailed description of the proposed hybrid DC Breaker, its design principles and proactive control with particular focus on the reliability of the concept. The modular design of the hybrid DC breaker for HVDC applications is described and results from prototype testing are presented. Furthermore, the application of the hybrid DC breaker associated with the design of a DC switchyard is discussed.
