配电网线损计算与分析中存在问题解决对策

Problems and Solutions in Distribution Network Line Loss Calculation and Analysis

详细研究了配电网线损计算与分析方法,指出现有线损计算与分析方法中由于负荷数据不完整造成的模型简化、影响线损的因素考虑不全面等各种问题。提出采用曲线基进行线损分析的新方法,为每一种线损影响因素建立数学模型和曲线模型。根据对线损曲线的分解,快速、准确、直观地确定线损的影响因素。

This paper studies the distribution network line loss calculation and analysis methods,points out all kinds of problems in line loss calculation and analysis which consist of the model simplification because of the incomplete load data and the effect factors of line loss which are not adequately considered and so on.The new method of the curve analysis based on line loss is proposed,which is through the establishment of mathematical model and curve model for each kind of line loss effect factor.According to the decomposition of line loss curve,the effect factors are determined quickly accurately and intuitively.
