Flexible DC converter valve

The globally pioneering ±800kV/5000MW flexible DC transmission system converter valve developed by TBEA Sunoasis Co., Ltd., is designed with non-locking overhead flexible DC transmission series technology, which solves the three major problems when flexible DC transmission system is applied to overhead transmission lines in the industry: DC fault self-clearing and system restart, reduced DC voltage operation and valve bank online withdrawal. In one fell swoop, the voltage level of flexible DC transmission has been raised from ±500kV to ±800kV, and the transmission capacity has been raised from 1 million kW to 5 million kW. In this way, the main performance indicators are at international leading level, leading the technical development of flexible DC transmission industry.
