| Abstract: | 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 kV 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. |
