摘　　要：天津电网在华北电网中属于受端,大量的电力需要长距离输送,加之天津经济发展较快,受用电量不断增长而电力走廊紧张等因素的影响,致使天津电网存在着电压失稳的威胁。借助连续潮流、模态分析和电压稳定指标等技术和分析手段,对天津电网的电压稳定性状态进行了深入的分析,指出了天津电网存在的问题和系统的薄弱环节,为天津电网更为安全稳定的运行提供了有益的信息。Tianjin Power System (TPS) is at the power receive-side of North-China Electric System (NCES), a great deal of electricity needs to transform from the west part of NCES to TPS through a long distance. With the fast development of economy the power consumption in Tianjin region increases rapidly and constantly in recent years, but new transmission corridor or new power plant can be hardly built because of the restriction of geographic condition of Tianjin region, therefore, the danger in voltage instability continuously exists. By means of following analytical approaches, such as continuation power flow, modal analysis and improed voltage stability indicator the voltage stability of TPS is thoroughly analyzed, and the weak node sets and existing problems in TPS are pointed out.
