Hybrid cascaded multi-terminal DC transmission topology scheme adopts LCC converter at the rectification side, inverter side uses high-end LCC converters in series with low-end multiple VSC converters. This topology solution can make full use of the advantages of LCC and VSC technology. As a new generation of HVDC transmission technology, hybrid cascade multiterminal still has many key technologies to broken. Through the development of hybrid cascade multiterminal HVDC dynamic simulation test system, the start-up, shutdown, high and low valves switching-back and DC fault self-cleaning of hybrid cascade multiterminal HVDC transmission are studied and tested. It provides technical support for the engineering application of hybrid cascade multi-terminal HVDC transmission technology.
