采用脉冲函数建立馈线等效负荷密度模型

提出了以脉冲函数为基的等效负荷密度模型简化配电网分析的方法。针对8种基本负荷分布,求解馈线两端的电压方程和馈线沿线损耗方程,分别获得各种分布的特征值和相似系数,从而不需要量测馈线沿线的各个负荷,也能计算出馈线电压降落和沿线线损。文中给出了若干实例,并与严格计算法、负荷均匀分布法的计算结果进行了比较,结果表明提出的方法是可行的

Equivalent load density models for feeders based on pulse function

An equivalent load density model based on pulse function for distribution networks is presented. Eight fundamental load distribution patterns are put forward. By solving the voltage drop function and the power loss function of the feeder line, characteristic values together with the corresponding similarity parameters for the eight load distribution patterns are obtained respectively. Consequently, voltage drop and line loss can be acquired without the data from each load on the feeder line. Examples are also given, and the comparison with other analysis results shows the feasibility of the proposed approach.
