Abstract: Transmission of large-scale wind power from the north of China fits the future need for the wind power development. A new power regulation scheme of large-capacity and long-distance DC transmission is proposed then for wind power . Based on the analysis of the characteristics of power surplus and regulating capacity surplus of the sending end system, the principle of complementary operation between the sending end system and the DC system is studied with a testing case established in details. The results show that, in the case of bulk wind power transmission, constant and steady DC transmission as well as efficient wind power utilization can be achieved, by giving play to the regulating capabilities of the sending end system. Finally, relevant measures are put forward to safeguard the implementation of such DC transmission regulations.
