摘 要:Hybrid high voltage direct current transmission(Hybrid HVDC)is a new type of HVDC technology developed in recent *** combines the characteristics of large-capacity and low cost of the line commutated converters(LCC)and non-commutation failure and dynamic reactive power support of voltage sourced converters(VSCs)in one HVDC *** has technical advantages in the fields of unidirectional power transmission and in the application of improving the stability of multi-infeed HVDCs,giving it broad application *** Kunbei-Liuzhou-Longmen(KBL)project is the first hybrid ultra HVDC *** was put into service on Dec.27th,*** paper introduces the KBL project,analyzes the operation characteristics of hybrid HVDC system,and provides on-site verification of KBL project,including operation of LCC-VSC hybrid system,ultra-high voltage VSC technology using the series of two valve groups,the DC fault ride-though of hybrid VSC without using DC breaker,the connection and disconnection of a third station,and etc.
