摘要
配网线损率的高低及综合线损率月度波动的大小受供电企业的售电量结构及规划设计、生产技术、经营管理水平等多种因素的影响。为此,建立了各种影响因素与线损率的关系模型,应用偏微分推导了量化分析售电量结构、专线管理水平、公用线管理水平等因素对配网线损率及综合线损率波动影响的计算公式。同时采用重庆江津供电局线损数据进行了实例计算和分析,验证了所提算法的有效性。
The distribution loss rate and the fluctuation of synthesis loss rate are affected by many kinds of factors,such as the composition of electricity sale,the level of production technology and the level of operation and management,etc.Based on the traditional calculation formulas for electric network loss rate,quantitative analysis formulas for the effect of distribution loss rate and the fluctuation of synthesis loss rate,to the factors,such as the composition of electricity sale,the management level of special lines and the management level of public lines,etc,were proposed in the paper.All formulas are derived with the application of partial derivative.Taking Chongqing Jiangjin Power Supply Bureau an example,calculation results verify the correcthess and validity of the algorithms.
