配电网理论线损计算与分析系统的研制

Development of Analysis and Management System for Theoretical Line Losses in Power Distribution Networks

以Power builder 6．5为开发平台，利用均方根电流法实现配电网理论线损计算、分析与管理。引入“等效容量”的概念处理配电网中的小电源（小水电和小火电），使含小电源的配电网线损计算简便可行，定义了完整的结构数组来表示节点的信息使计算结果中包含所有节点和支路的理论线损信息，提出基于队列的算法进行线损计算以提高效率。系统基于Windows环境，可以提供配电网理论线损管理所需报表。

An analysis and management system for theoretical line loss， based on“root mean square current” method， is developed， which using Power builder 6．5 as development platform． “ Equivalent capacity method ” has been introduced to deal with little power source， which makes it simple and viable to calculate line loss of feeder contained little power source． A complete data structure contained the loss value of every node and branch has been defined to represent nodal information． An algorithm based on sequence is proposed to improve computational efficiency． The system is based on windows operation system and can provide line loss management form．
