摘　　要：为了研究750/330 k V电磁环网解环后甘宁断面静态稳定极限,采用基于阻抗特性的等值建模方法,对甘宁断面进行等值建模简化,计算出各种方式下静态稳定极限,并与静态稳定极限实用方法计算结果进行对比。结果表明:基于阻抗特性的建模方法能够准确模拟实际系统的潮流分布特性,静稳极限的理论计算结果与实用方法仿真结果基本一致。In order to research static stability limit of Gansu-Ningxia section after 750/330 kV electromagnetic loop breaking up,adopts equivalent modeling method based on impedance characteristic,obtains the equivalent simplified model of Gansu-Ningxia section,calculates static stability limit under various modes and compares the calculation results with the practical method results. The result shows that the modeling method based on impedance characteristic can accurately simulate tide distribution characteristic of the real system,the theoretical calculation result of static stability limit is basically consistent with the simulation result of the practical method.
