The geographical characteristics of large mountains and large gaps in the region lead to low efficiency of distribution network infrastructure transformation. The traditional expansion scheme is easy to cause no-load waste of distribution transformers, and it is difficult to meet the sudden increase in electricity demand during the Spring Festival return of 6 million migrant workers. In this paper, by developing a new type of power transmission lifting device, integrating dynamic voltage regulation and intelligent compensation technology, the output current is stabilized and the voltage quality is optimized during the peak period of power consumption, and the low voltage problem of users with ultra-power supply radius is effectively solved. The device adopts modular design, which can be flexibly deployed at the end of the distribution network, significantly reducing the no-load loss caused by the new distribution transformer, and avoiding the defects of large investment and long cycle of infrastructure projects. The application results show that the scheme can not only improve the voltage qualification rate to more than 98%, but also reduce the operation and maintenance cost by about 40%. It provides an efficient, economical and sustainable low-voltage governance paradigm for mountainous rural power grids, and has important practical value for the upgrading of power services under the rural revitalization strategy.
