摘要
电压质量是农村配电网建设与改造的关键指标之一,配电网馈线的电压偏移快速估算能提高项目规划与评审的效率。本文根据配电线路的运行特性、理论电压降落、电压偏移公式,利用MATLAB/Simulink软件进行仿真分析,获得配电网电压偏移与负荷、线路长度相对应的特性曲线,通过特性曲线获得导线满足电压降落的负荷区间,并设置逻辑判别图,可以快捷的查询电压偏移情况,为配电网规划提供方便实用的电压偏移计算工具。
According to the operating characteristics of distribution lines, theoretical voltage drop and voltage excursion formular, the simulation analysis is carried out by MATLAB/Simulink software in the paper. The voltage excursion of the network voltage and the rlative characteristic curves of load and line length have been obtained, which meet the load ineervals of the voltage drop by the characteristic curves, and set up the logical identification diagram, which can quickly inquire ahout the voltage excursion conditions, providing convenient voltage excursion computing tool for distribution network plan.
