摘　　要：特高压灵绍直流投运后,浙江电网运行特性发生重要转变,省内主要受电断面由钱塘江断面转变为宁绍台温"十线断面",系统电压稳定存在薄弱环节。基于上述原因,首先分析了2016年灵绍直流馈入后,浙江交直流混联电网主要运行特征,并开展静态电压稳定裕度和暂态电压稳定特性分析,得出关系到浙江电网电压稳定的薄弱环节和关键机组。相关研究成果为浙江交直流混联电网的优化运行和调度提供了参考。With the operation of Lingzhou-Shaoxing UHVDC,operating characteristic of Zhejiang power grid alters significantly. The major power-receiving section in Zhejiang changes from Qiantang River section to ＂ten- line section＂ of Ningbo, Shaoxing,Taizhou and Wenzhou,and there are weak points in voltage stability of power system. In view of the above reasons,operating characteristic of AC/DC hybrid power system in Zhe-jiang is analyzed with infeed of Lingzhou-Shaoxing DC transmission lines in 2016; besides, static voltage stability margin and transient voltage stability characteristic are analyzed to conclude weak points and critical generators concerning voltage stability of Zhejiang power grid. The research findings provide reference to opti-mal operation and dispatching of AC/DC hybrid power system in Zhejiang.
