Abstract

This paper proposes a new synthetic test circuit (STC) to confirm the switching operation of thyristor valve in HVDC converter. The proposed STC uses a 6-pulse thyristor converter with 2-phase chopper as a high-current source to provide turn-on current to the test valve. The operation of proposed STC was verified through theoretical analysis and computer simulations. Based on computer simulations, a hardware scaled model was built and tested to confirm the feasibility of implementing a real-size test facility. The proposed system has an advantage of simple structure and operation over the existing system.
