Abstract:Compared with the conventional HVDC project, the inverter station of Yongren-Funing HVDC project has a variety of power transmission and operation mode: “all to Guangxi”, “all to Yunnan” and “Pole 1 to Guangxi, Pole 2 to Yunnan”. Power “Pole 1 to Guangxi, Pole 2 to Yunnan” the dispensing operation mode is referred to the inverter station power will be transported to different AC asynchronous electrical network. In order to adapt and meet the special operation mode, new control strategy is needed for the DC control system. According to the characteristics and requirements of Yongren-Funing HVDC project, this article carries out a detailed study of power control mode, automatic power control, grounding current limit etc, and a new design idea and implementation principle are proposed. The new control strategy has been implemented and verified by DC control simulation system, and has been applied in Yongren-Funing HVDC project.
