摘要：

The working principle of the controlled current source converter in HVDC transmission was analyzed from the DC side and the AC side respectively, and the influencing factors of the key parameters of the AC and DC side of the controlled current source converter were obtained. On this basis, the filter capacitor and connection transformer were designed with the minimum number of series devices of converter valve as the goal. The filter inductor was designed based on the harmonic attenuation characteristics of the AC side current. And the parameters of the DC choke were designed from five aspects. Finally, the simulation model of the two ends of the system was built in PSCAD/EMTDC, and the simulation results show that the design method of the main parameters of the system is reasonable and feasible. © 2022 Chin.
