Travelling wave directional pilot protection for hybrid HVDC transmission line
International Journal of Electrical Power & Energy Systems, 2019As known, hybrid high-voltage direct current (HVDC) is wide applied in power system. Because two converter stations are line commutated converter based HVDC (LCC-HVDC) type and voltage source converter based HVDC (VSC-HVDC) type respectively, the HVDC ...

Hybrid HVDC system for power transmission to island networks
2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004A hybrid system, comprising a line commutated thyristor HVDC converter and a STATCOM, is proposed in this paper for the connection of networks with no synchronous generation to a main grid. The proposed system combines the robust performance and low capital cost and power loss of a line-commutated HVDC converter, with the fast dynamic performance of a ...
