基于面向对象技术的电力系统谐波潮流程序开发

The Development of Harmonic Power Flow Program Based on Object-oriented Technology

介绍了面向对象技术在电力系统中的应用;针对目前对谐波源的建模都比较简单,缺乏详细的谐波源模型,采用面向对象技术开发了电力系统谐波潮流程序,在给定谐波量的前提下分析了谐波在电网中的分布情况。最后,以IEEE-3机12节点系统为例进行了分析计算,确定谐波在电网中的分布情况,并按照谐波国家标准GB/T14549-93检查了各个母线节点的谐波是否达标。

Introduced application of object oriented technology in power system, developing harmonic power flow program with object oriented technology. Due to the simple model of the harmonic source and lack of more precised ones at present , the key of the paper was to analyse the harmonic distribution situation in power grid when harmonic was given, which was of important practical meaning to power system analysis. Finally, an analysis was carried out by taking the IEEE 3-machine 12-bus system as an example to describe distribution situation of harmonic in power grid. According to the national standard of harmonic GB/T 14549-93, each bus node would be checked up whether it can reach the standard or not.
