摘要
谐波检测是谐波问题的一个重要分支,对能够准确、实时地对电力系统谐波进行检测有着重要的意义。本文介绍了一种基于快速傅里叶的谐波检测方法,并应用其原理设计了一种基于DSP和AVR的新型谐波检测装置,该装置可完成国标规定的电能质量指标的测量,并有数据显示、存储和通信等功能。工程实际测量结果验证了该方案的可行性和可靠性。
Harmonic detection is an important branch of the problem of harmonic. In electric power system, the accurate and real time detec- ting for harmonic measurement is very meaningful. This paper designs a harmonic new method of testing based on FFT, and applicating its principle to design a surveillance equipment on power quality by double CPU technology which can accomplish the measuring of liower quality index stipulated by national standard and have some other functions such as data showing, data saving, communicating,etc. The feasibility and reliability of the proposed scheme is validated by measured results of practical engineering project.
