| 摘 要： | 谐波对电力系统和用电设备产生了严重危害和影响.谐波检测是谐波问题的一个重要分支,实时、精确地对电网谐波进行检测有着重要的现实意义,但传统的谐波检测方法有很多缺点.随着数字信号处理技术的发展,小波变换作为一种较有效的方法,也被应用于对电网的谐波检测中.本文利用基于多分辨率分析的小波变换对电网谐波信号进行分析,理论分析和仿真结果都证实了该方法的有效性.

| Abstract: | Harmonic is harmful to electric power system and electric equipments.Harmonic detection is an important branch of harmonic problem.The real-time andaccurate detecting for harmonic measurement has much practical meaning.But the traditional harmonic detection method has many shortcomings.As the development of digital signal processing technology,the wavelet transform,which is regarded as an effective way,has been widely applied to the analysis of the power network harmonic detection.The study analyzed the power network harmonic signals by wavelet transform based on multi-resolution analysis.Theoretical analysis and simulation results approved the validity of the detection technique. |
