To meet the thyristor valve operation test requirements of the Ximeng-Taizhou ±800 kV/6 250 A project, a new-type synthetic test circuit is built. The main features of the test circuit and the principal problems that need to be addressed are introduced. The main equipment parameters of the synthetic circuit are investigated and used for the operation test of ±800 kV/6 250 A thyristor valve. The test result shows that the proposed synthetic test circuit can meet the operation test requirements of the ±800 kV/6 250 A thyristor valve, and the rationality and reliability of the thyristor valve design are verified.
