摘要：
To avoid line overload, the transmission capacity of Jiangsu power grid's cross river channel urgently needs to be expanded. However, due to the natural danger of the Yangtze River, the development of cross river transmission channel resources in the province is extremely difficult, and existing power grid facilities can only be fully utilized. Therefore, a planning scheme for constructing a north to south direct current transmission channel in the province through the AC to DC conversion project has been proposed. This paper analyzes the oscillation risk and damping characteristics of Jiangsu power grid after provincial DC connection, and proposes an additional robust damping control strategy based on provincial DC to suppress oscillation phenomena under various faults and improve system fault recovery characteristics.
