间谐波检测在扰动分析中的应用

Application of Interharmonics Detection in Disturbance Analysis

随着分布式能源逐步接入电网,其中间谐波的含量大大增加。间谐波本身承载了较多涉及系统和设备运行状态的有效信息,可以利用这些信息实现某些判断和推测。首先简要介绍了不同的间谐波危害和检测方法,其次论述了间谐波分析在闪变测量和交流电弧故障检测中的应用,以便更好地理解其实际应用价值;同时指出现有利用间谐波进行数据分析的技术性不足,并讨论了这种应用的发展趋势。

With the gradual integration of distributed energy into the power grid,the content of inter-harmonicsis greatly increased.The interharmonics carry more effective information concerning the operating status of thesystem and equipment,and using this information can achieve certain judgments and conjectures.Firstly,thedifferent interharmonic hazards and detection methods are briefly introduced.Secondly,the application of interharmonicsanalysis in AC arc fault detection and flicker measurement is discussed in order to better understandits practical application value.At the same time,the data analysis using interharmonics is point out the technicaldeficiency,and the development trend of this application is discussesed.
