DC circuit breakers offer protection to dc systems. In HVdc systems, two types of breakers are available.
In HVdc systems, two types of breakers are available. The first type, electromechanical circuit breakers, are available up to 500 kV and 5 kA; the second type, solid state circuit breakers based on gate-commutated thyristor (IGCT) or insulated-gate bipolar transistor (IGBT) s, have typical ratings of 4 kV and 2 kA.
Solid state dc breakers are also used in low voltage DC systems, e.g., shipboard power systems.
In November 2014, the Global Energy Interconnection Research Institute developed a 200 kV hybrid DC circuit breaker with a breaking capacity of 15 kA/3 ms which was applied to the Zhoushan Flexible DC Grid Project in 2016 (Zhou et al. 2015; Tang et al. 2016; Qiu et al. 2018).
