Line Loss Analysis And Loss Reduction Measures In Typical Area Of Rural Power Network

Line loss refers to the total loss from the power plant to the user in the process of using electricity.After statistics,it is found that the problem of low voltage line loss in rural power network is serious and the power consumption is huge.In order to solve the problem of line loss in rural power network,the single index of line loss rate is used to evaluate the degree of line loss in rural power network and the reduction measures are too simplified.Based on the project background of "Line Loss Analysis and Loss Reduction Measures for Typical Stations of Agricultural Power Network",this thesis first introduces the concept and significance of line loss and line loss rate and the main components of line loss,then analyzes the causes of line loss in rural power network station area,After analyzing the advantages and disadvantages of the centralized theory line loss calculation method,the author selects the optimized equivalent resistance method to do the theoretical calculation of the rural network area..Secondly,according to the power supply radius,per capita electricity sales and transformer capacity,eight types of stations are classified,which is prepared for the following loss reduction measures.Line loss is not evaluated by the single index of line loss rate,which makes the evaluation of typical stations of rural power network deeper and more stereoscopic.Then,the weights of each index of the comprehensive evaluation system of the rural power network are determined,and the objective assignment method of sensitivity weights is proposed.The improved AHP and sensitivity weights fusion method are used to determine the weights of each station area.The quantitative evaluation is carried out for each station area,and the line loss level of each station area is evaluated comprehensively.Finally,the loss reduction measures in typical stations of rural power network are analyzed from two aspects of management measures and technical measures,and the combined loss reduction scheme of multiple loss reduction measures is proposed.Finally,the benefit and cost of loss reduction in rural power network are analyzed,and the final loss reduction scheme is determined in the view of economy and technology.
