摘　　要：为便于实时监测谐波和加强谐波管理,针对电力系统谐波的特点,本文研究了一种实时在线谐波检测与分析系统的设计与实现方法。该方法采用了傅立叶算法的基本原理并结合80C196单片机实现了具体的检测过程,满足实时在线检测的要求。该系统同时配备基于可视化用户界面的VC开发的谐波数据分析软件。该系统软件可对实时、历史数据进行分析,为电力系统谐波的检测和抑制提供了重要的依据。According to characteristic of electric power system harmonic, real-time analysis system is designed in this paper. It can serve for people who take charge online harmonic detection and of the harmonic detection and management. The basic principle of the fourier algorithm be introduced. In order to fulfill the need of real-time online, the whole process is carried out with 80C196 SCM. The system software is based on visual user interface which is programmed with VC. Real-time harmonic data and history data also can be analyzed and reference can be afforded in power system harmonic control.
