Research on self-reliance innovation in HVDC power transmission technologies

HVDC power transmission projects take the key role in transmitting electric power from the west area to the east in China.However,the main equipments of the existing HVDC projects were provided in set by foreign providers,and the core technologies of set design,manufacturing,installation,and commissioning were dominated by the foreign providers.With the capacity of HVDC power transmission taking more and more quotient in power transferring from the west area to the east in China,the self-reliance progress of the HVDC power transmission technologies becomes instancy.Aiming at the main issues of self-reliance progress of the HVDC power transmission technologies,the paper introduced the self-reliance innovation in the HVDC and UHVDC technologies conducted by CSG Technology Research Center.Some proposals on self-reliance research and development of UHVDC equipment are brought forward.
