采用固定变电站审批程序复杂、构筑物多、建设工期长，不能满足工程项目施工电力快速供应的需要，车载移动变电站克服了这些缺点。以吉图珲客运专线项目施工供电为背景，对车载移动变电站在吉图珲客运专线项目施工供电中的应用进行监测和分析。主要研究内容和结论如下： 1）通过研究车载移动变电站技术在吉图珲客运专线施工供电中的使用情况，证明车载移动变电站完全满足吉图珲客运专线施工需要； 2）与传统供电技术进行对比和分析，可以据此判定车载移动变电站技术在施工、使用过程中远优于传统供电技术； 3）车载移动变电站技术在吉图珲客运专线的成功使用，是符合当前快速施工建设需要的新技术，对未来施工供电具有指导作用。

Conventional fixed substation has such disadvantages as complex approval procedure, numerous structures and long construction period, therefore it cannot meet the requirement of rapid power supply. As a result, vehiclemounted mobile substation is used. The application of the vehiclemounted mobile substation in the construction of JilinTumenHunchun passengerdedicated railway is monitored and analyzed. The main study contents and conclusions drawn are as follows: 1) The application of the vehiclemounted mobile substation in the construction of JinlinTumenHunchun passengerdedicated railway is studied, which shows that the vehiclemounted mobile substation adopted can meet the requirement of the power supply; 2) Comparison and contrast is made between the vehiclemounted mobile substation and the conventional fixed substation, which shows that the vehiclemounted mobile substation is superior to the conventional fixed substation; 3) The successful application of the vehiclemounted mobile substation in the construction of JilinTumenHunchun passengerdedicated railway shows that the vehiclemounted mobile substation technology is a kind of new technology that can meet the requirement of rapid construction, which can provide reference for the construction power supply of similar projects in the future.
