配电网理论线损计算与分析系统的研制

Development of Analysis & Management System for Theoretical Line Loss of Power Distribution Networks

以Powerbuilder 6.5为开发平台 ,研制了一套利用均方根电流法进行配电网理论线损计算与分析系统。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 ;并提出一种基于队列的算法进行线损计算用以提高计算效率。系统基于Windows系统 ,可以提供配电网理论线损管理中所需报表。

A theoretical line loss analysis and management system that based on root mean square current method is developed by use of Power Builder 6.5 as development platform. Equivalent capacity method, which makes it simple and viable to calculate line loss of feeder containing little power source, 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 necessary form of line loss management.
