摘　　要：文章针对配电网末端低电压问题,展开低电压产生的机理和电压分布特性分析研究。通过线路参数与运行电气参数的关系,揭示电压降落产生的机理;设计了分段集中参数的电压计算方法,对配电变台出口到线路末端全线的电压分布进行计算;以典型配电台区和负荷分布为例对电压特性和电压分布进行了分析,结果表明,线路电压沿线路近似呈指数降落。In this paper,the mechanism of low voltage generation and the characteristics of voltage distribution are studied.The mechanism of voltage drop is revealed through the relationship between the line parameters and the operating electric parameters.The voltage calculation method of piecewise lumped parameters is designed to calculate the voltage distribution.The voltage characteristics and voltage distribution are analyzed with typical distribution stations.The results show that the line voltage falls exponentially along the line.
