摘　　要：特高压电网形成初期,网架结构薄弱。为解决特高压投运初期线路静稳极限偏低和动态无功补偿能力不足的问题,探讨了提高特高压互联电网稳定性的措施。通过比较分析增加串联补偿电容、增加可控高压电抗器、新建特高压变电站等措施,提出采用可控高压电抗器和新建变电站能有效提高电网稳定水平。The structure of power network is weak in the initial interconnected UHV power grid. In order to improve the problems about the low limitation of transmission power and the lack of dynamical reactive power compensation, the measures are presented to enhance the stability of the interconnected power grid. Based on the analysis and comparison of fixed series com- pensation, controllable reactors and building UHV substation, an effective way that adopting the controllable reactors or building UHV substation is proposed to improve the stability of UHV interconnected power grid.
