The invention provides a priority analysis and selecting method of different energy-saving loss-reduction technologies for urban and rural distribution network. According to the technical characteristics, the energy-saving loss-reduction technologies are classified into the following five categories: (1) reforming metering device and treating harmonic wave; (2) performing reactive power compensation for a distribution transformer, circuits and applying reactive power optimization configuration software; (3) applying an economical operation system of the distribution transformer; (4) reforming the distribution transformer, the distribution circuits and low-voltage circuits, and applying a single-phase distribution transformer and a circuits voltage regulator; (5) reforming the boosting of the distribution network and leading high voltage into a load center. According to technical characteristics of each category, including realization ways, the five categories are subject o the analysis of mutual influence and ranks the priorities, thus corresponding reforming technology can be selected according to the priority of each reforming technology during the reforming of different kinds of equipment, thereby reducing the energy-saving loss-reduction cost.
