针对目前宁夏电网存在甘-宁断面多回联络线停电检修的现状，通过对甘-宁断面三回联络线进行停电方式下系统的热稳定、静态稳定、暂态稳定、动态稳定和小干扰稳定仿真计算分析，确定甘-宁断面在薄弱方式下对系统的稳定性影响。结果表明：甘-宁断面在多回联络线停电检修方式下对系统的稳定性影响较大，需对甘-宁断面采取预控措施，防止热稳定和动态稳定问题的发生。

Ningxia Power Grid currently exists the status quo of Gansu-Ningxia section multiple loop interconnector outage maintenance,by simulation and calculation analysis on system’s thermal stability,static stability,transient stability,dynamic stability and little interference stability under the mode of Gansu-Ningxia section triple loop interconnector outage, confirms the stability influence of Gansu-Ningxia section on system under weak mode. The result shows that Gansu-Ningxia section has larger influence on system stability under the mode of multiple loop interconnector outage maintenance,needs to take prevention measures for Gansu-Ningxia section, prevents the problem of thermal stability and dynamic statility to occur.
