110 kV移动式变电站实用技术研究

Research on Practical Technology of 110 kV Mobile Substation

为了合理设计和使用移动变电站,阐述了移动变电站的应急抢修模式、短暂替代模式、中长期固定模式等运行模式。介绍了110 kV移动变电站的设计、运行和维护,并通过仿真软件研究了移动变电站运行对供电网络的影响。分析结果表明,在重负荷或新增大负荷的情况下采用移动变电站转移部分负荷能够降低网络损耗,维持合理的电压水平。

With the purpose of rational design and usage of mobile substation, this paper expounded several operational modes, such as emergency repair, transience replacement, and medium and long term fixation. Introduction was made to the design of 110 kV mobile substa-tion and its operation and maintenance. The simulation software was used to research the impacts of the mobile substation operation on the supply network. The analysis result shows that under the conditions of heavy load or newly increased heavy load, the method adopting the mobile substation to transfer the partial load could reduce the electric network losses and maintain the rational voltage level.
