Provided is a synthetic test circuit for synthetic-testing a thyristor valve in high voltage direct current (HVDC). A resonant circuit applies forward DC current, a reverse DC voltage, and a forward DC voltage to synthetic-test the thyristor valve. A current generation unit generates DC current that is above a reference current value to supply the generated DC current into the resonant circuit. A voltage generates unit generating a DC voltage that is above a reference voltage value to supply the generated DC voltage into the resonant circuit. The resonant circuit includes a charging auxiliary valve for charging a gate driver of the thyristor valve.

Test circuit for thyristor valve in HVDC system

Disclosed is a HVDC valve tower. The HVDC valve tower includes cylindrical valve module loading part, a valve module loaded on the valve module loading part, and a crane disposed at a center of the valve module loading part to be rotatable.
