摘　　要：归纳提出了特高压交直流混联受端电网静态稳定分析通用流程,探讨了影响静态稳定分析准确度的多种关键因素及处理原则。详细计算分析了±800 k V宾金和灵绍两回特高压直流密集馈入后,浙江电网的静态功角和静态电压稳定特性,并针对特殊方式下浙江电网静态稳定裕度下降等情况,提出了有针对性的预防措施。相关研究成果为新形势下浙江电网的优化运行和调度提供了理论依据。This paper presents the general procedure for the static stability analysis of the ultra-high voltage AC/DC receiving power grid firstly and discusses the main factors which influence the simulation accuracy and treatment principles. Then, the static angle stability and static voltage stability characteristics of Zhejiang hybrid ultra-high voltage AC/DC receiving power grid is analyzed after the ±800 k V Binjin and Lingshao projects commissioned. And some preventive countermeasures are proposed to overcome the decline of the static stability margin under some particular conditions. The analysis results provide theoretical reference for the operation and optimization of Zhejiang power grid.
