Study On Meticulous Analysis And Energy Saving Technology Of The Loss Of Urban And Rural Distribution Network

The ratio of power network's energy loss is an integrated economic indicator. It not only reflects the rationality of the power network's structure and operation mode, but also reflects the level of the power units' technique and management. So, meticulous analysis of the loss of urban and rural distribution network and the study of energy saving technology are necessary for power system. The mathematical model of the loss of power components is established in the paper. Line loss is calculated and analyzed according to different components, different voltage levels, and different substations respectively. Meticulous analysis of technical line loss is completed and suggestions to reduce the loss to the managerial line loss are proposed. The relevant energy saving measures are studied and applied in the demonstration area based on the results of meticulous analysis. By the meticulous analysis of high, medium and low voltage energy loss of Yangjiaping bureau , data can be provided for energy saving work. In considering high and medium voltage power grid energy reduction, focusing on processing the lines and transformers which have larger proportion in energy loss. In considering low voltage network energy reduction, focusing on processing the user meters and lines , including mian lines and hosehold lines, which have larger proportion in energy loss. Through the calculation of line losses of typical regions, the rate of energy loss in high-voltage transmission netwok is relatively low, the rate in the medium and low voltage distribution network is higher than high-voltage transmission grid can be got. Energy saving work in the medium and low voltage distribution network is a major part of the consideration.The example of meticulous analysis of Yangjiaping bureau indicates the advantages and effectiveness of the method.
