Abstract: Due to the lack of rationality of distribution network layout in rural areas, large reactive power shortage and inadequate line loss management, the security of power supply system can not be fully guaranteed, and unnecessary loss and waste are increased to a certain extent, which can not meet the strategic needs of sustainable development in the new era. this paper will analyze the loss problems existing in the rural distribution network construction of power supply enterprises, and put forward the loss reduction and energy-saving technical countermeasures, hoping to provide reference for the project management level.
