DC Transmission Grid With Low-Speed Protection Using Mechanical DC Circuit Breakers [PDF]
IEEE Transactions on Power Delivery, 2015 This paper introduces a dc transmission grid with fault-tolerant inductor-capacitor-inductor (LCL) voltage-source converters (VSCs) and using a slow protection system based on mechanical dc circuit breakers (CBs). LCL VSC inherently regulates dc fault current to levels that converters can sustain for prolonged periods which avoids insulated-gate ...
