Research and Application of Line Loss Treatment Technology of the High Loss Motor-Pumped Well's Electrifying Transformer District

In order to solve the problem of excessive line loss in the transformer district caused by the difficult shutdown and long-term no-load operation, in this paper, the intelligent falling type fuse was introduced into the treatment of line loss in the transformer district. Firstly, a design concept was proposed to reduce line loss in the transformer district by automatically switching on intelligent falling type fuses. Secondly, using correlation analysis, the main factors that affected its automatic switching were determined. Based on this, the influence weights of different influencing factors were determined, and the weighted evaluation values of each influencing factor were obtained by combining each influence weight with the initial value. Based on this input, an automatic switching calculation model based on neural network was constructed, and an intelligent falling type fuse automatic switching control method was further proposed. Finally, a county-level motor-pumped well's electrifying to transformer district line loss treatment system was constructed, and typical transformer districts were selected for on-site application. Through the comparison of the data before and after the treatment of the line loss, it was proved that the treatment technology can achieve effective treatment of the line loss in the motor-pumped well's electrifying transformer district, and the monthly line loss rate can be reduced to less than 2.5%, with a decrease rate of 83.3%.
