摘　　要：基于PSASP仿真平台,搭建了包含金上-湖北特高压直流(金上直流)的2025年电网模型,分析了特高压直流接入后对湖北电网短路电流、潮流疏散、暂态稳定的影响,在此基础上提出了相应的稳定运行控制建议,研究结果对湖北电网规划和运行具有一定的指导作用。Based on the PSASP simulation platform,this paper constructs a 2025 power grid model containing Jinshang-Hubei(i.e.,the transmission line from Jinsha River upstream hydropower unit group to Hubei province)UHVDC,and then analyzes the influence of the Jinshang UHVDC access on short-circuit current,tidal current diversion and transient stability of Hubei power grid.On this basis is puts forward the corresponding stable operation control suggestions.The results of the study have a certain guiding role for Hubei power grid planning and operation.
