Abstract: This paper designed a back-to-back (BTB) operational test circuit for high-voltage thyristor valves, which could be used as the current test platform for thyristor valves, but also be used as the long-turn operational test platform of reactive power compensation equipment, such as SVC, SVG. With the reference to the BTB DC system of HVDC transmission parameter, the circuit was designed to realize large DC current operation and returned the active power, so that the energy consumption of the entire system is greatly reduced. The computer simulation was carried out to verify the correctness of the design parameters, so as to lay the foundation for synthetic test circuit of thyristor valves.
Key words: thyristor valve; reactive power compensation equipment; back-to-back; operational test
