A Statistical and Technical Deviations Based Analysis Approach for Line Loss Rate in Low-voltage Transformer District
To address the issue of identifying the causes of ab-normal line loss rates in low-voltage transformer district,a new line loss rate analysis method based on statistical and technical deviations was proposed.Firstly,combined with MATLAB nu-merical simulation,the ideal line loss rate was introduced by analyzing the statistical line loss rate and theoretical line loss calculation model.On this basis,the relationship among statist-ical line loss rate,theoretical line loss rate and ideal line loss rate was compared and analyzed to obtain the indexes of statist-ical and technical deviations.Then by comparing the deviation index with the threshold,the cause of abnormal line loss rate can be determined and corresponding loss reduction measures can be formulated.Finally,engineering practice has confirmed the effectiveness of this scheme in identifying the causes of ab-normal line loss rates.After implementing appropriate technic-al loss reduction measures,the technical deviation index of the transformer district decreased from 1.2 to 1.0,and the line loss rate decreased from 3.1% to 2.5% under the same power sup-ply.
