A novel hybrid HVDC system is proposed based on the traditional LCC HVDC system. The proposed system is able to achieve full elimination of commutation failures which cannot be achieved in traditional LCC HVDC systems. In addition, reactive power controller is designed for the hybrid HVDC system. The controller is able to achieve zero reactive power exchange with the connected AC system at inverter side. It can also facilitate a faster fault recovery. Finally, the black start capability of the hybrid system is investigated. The black start sequence and inverter AC voltage controller are designed to achieve smooth and reliable black start of inverter AC system. The performances of the proposed system and controller are validated through detailed simulations in Real Time Digital Simulator (RTDS).
