System realization of CASHIPS DC high power test facility

Aims to complete the test of the International Thermonuclear Experimental Reactor (ITER) poloidal field (PF) converter system, and to meet future continuous upgrading needs of a modern industrial power system and scientific research, direct current (DC) high-power test facility of Hefei Institutes from Physics science, Chinese Academy of Sciences (CASHIPS) is built in 2011. As the largest DC high-power test facility in China, the rated steady state DC current is 120 kA and the pulse peak current is 500 kA. Four thyristor-based AC/DC converter modules are paralleled to handle this huge current. In May 2017, 15 testing items are accredited by the China National Accreditation Service (CNAS) for Conformity Assessment . Tip to now, the test for 17 devices of 16 companies and manufacturers in the world have been completed. In this paper, the topology and the control of DC High-Power test facility are presented. In addition, the testing capability and the completed tests of DC high-power test facility are illustrated.
