Patent abstract
A cascade converter station and a multi-end cascade high-voltage direct current (HVDC) power transmission system. The converter station includes a low-voltage end converter station (11) and a high-voltage end converter station (12). The high-voltage end converter station (12) is connected in series with the low-voltage end converter station (11) through a medium-voltage direct current (DC) power transmission line (13) and connected to a HVDC power transmission line (14). With the cascade converter station and the multi-end cascade HVDC power transmission system, HVDC power transmission can be achieved in a flexible, reliable and economical manner.
