So you have power circuit breakers at your facility, and they seem to be just fine, sitting there quietly doing their job. What you may not realize is that even though your circuit breakers are ...
Abstract: Due to the lack of commercialized high voltage DC circuit breaker (DCCB), the protection of voltage source converter-based (VSC) multi-terminal HVDC (MTDC) grid is still a main obstacle ...
Abstract: This paper proposes a DC fault protection strategy for large multi-terminal HVDC (MTDC) network where MMC based DC-DC converter is configured at strategic locations to allow the large MTDC ...
Georgia Tech is to develop circuit breakers for >1MW dc power links up to 100kV – with wind farms, electric aircraft and electric ships in mind. Direct current power transmission is more efficient ...
To date, all Voltage Source Converters (VSC) used in HVDC networks are incapable of clearing faults on the DC side of the converter. “For most of the situations where such converters have been used so ...
In an effort to meet worldwide efficiency requirements, engineersare designing offline power supplies integrating high-efficiencyswitching-regulator-control circuits. This approachuses less copper and ...
