Abstract: Based on the characteristics of the voltage and current stress during the normal operationofthyristor control reactor (TCR) valve bank, this paper gave a synthetic circuit test scheme for TCR bidirectional thyristor valve bank.The Y type connection mode was used to realize the big current output of TCR and the direct current voltage source and the voltage oscillation circuit was used to realize the infliction of valve bank big voltage. On this basis, a test system with the highest voltage of 110 kV and a maximum current of 4 000 A was built. In this test circuit the running test of TCR valve bank with nominal voltage of 20 kV and nominal current of 2 700 A was completed. The test results show that the test system can fully meet the requirements of the TCR valve type test which was requested in IEC and national standard, and it can complete the full operating performance test.Through the use of the synthetic circuit, the development speed of TCR valve can be greatly accelerated, and the developed valve can be guaranteed.
