This paper conducts research on the functions and performance of multi-terminal hybrid UHVDC systems. According to the operating characteristics of half-bridge and full-bridge mixed VSC, this paper analyzes how to realize the hybrid connection of LCC and VSC through external characteristic matching. The special functions and operating characteristics of multi-terminal hybrid UHVDC under core operating conditions such as AC and DC faults ride-though and valve online switching-in-out are studied in detail. Finally, the real-time simulation platform was used to verify the analyzed characteristics and designed functions in the hardware closed-loop test.
