摘要：
The construction cost of the modular multilevel converter (MMC) of the offshore dc transmission system is relatively high, due to the large number of the submodules and the large size and weight of MMC. To address this problem, this paper studied the hybrid dc transmission system with auxiliary converter and diode rectifier connected in parallel and introduced the operation principle of the hybrid converter. A novel topology of the auxiliary converter was proposed. The operation principle was analyzed systematically and the mathematical model was given. Based on the mathematical model, the control and parameter design method of the auxiliary converter were also proposed. Comparing with the MMC, the construction cost of the offshore converter station is significantly reduced and the system efficiency is improved. Then the feasibility of the topology and control of the hybrid converter is verified through the simulation and the hardware-in-loop experiment. © 2021 Chin. Soc. for Elec. Eng.
