摘要
本系统为了掌握谐波源的注入对区域电网的影响而开发的。运用虚拟仪器、Visu-alC++语言编程、SQL-Server数据库、ACCESS数据库等技术构建了区域电网谐波在线评估系统。在获得区域电网参数及注入谐波源相关参数的基础上建模并分析计算,得出节点谐波电压电流等参数,进而对电网谐波整体情况进行有效评估。
The system is developed for realizing the effect on regional electric network that the injecting of harmonic source might cause. The evaluating system of regional electric network harmonic is composed of virtual instrument,visual c ＋＋ programming,SQL-Server （Structured Query Language）, ACCESS and so on .With this system, the parameters of node harmonic voltage and current are coming into being automatically after modeling and calculating based on the parameters of regional electric network and harmonic source ,then the harmonic of the whole regional electric network can be evaluated.
