摘　　要：2017年蒙西至湖北±800 k V特高压直流输电通道建成,将与湖北电网现有交流特高压输电通道一起,形成特高压交直流并联的格局,对湖北电网的结构形态、运行特性变化产生重要影响。以2017年湖北电网丰大运行方式为背景,根据湖北电网规划电力流,利用仿真软件PSASP建立湖北电网网架结构模型。采用连续潮流算法计算求取湖北电网对蒙西特高压直流的消纳极限,并对消纳极限运行方式下的湖北电网进行稳定校核,包括静态安全分析、单一故障及严重故障的暂态稳定校核。±800 kV Mengxi-Hubei UHVDC transmission lines will be built in 2017, which will have formed a UHADC parallel power system with the existing UHVAC transmission lines in Hubei province. It will have a great influence on the structure and operation characteristics of Hubei power grid. Based on the operation during high flow periods and planning capacity of power delivering of Hubei power grid in 2017, the network structure model was set up with using PSASP software. The continuation power flow （CPF） algorithm was used to calculate the power transfer limit of Mengxi-Hubei UHVDC transmission lines. The stability of Hubei power grid was verified with the Mengxi-Hubei UHVDC transmitting limit power, which included static security analysis, transient stability check of single and serious fault.
