| 摘要: |
| 论述了间谐波检测装置的研制，介绍了间谐波检测算法（迭代DFT算法）的优点、硬∕软件设计流程、装置的校验方法及实验结果；提出了“间谐波记录”这一概念，有利于衡量电力系统中间谐波的含量。对3种典型间谐波源进行了间谐波的实际测量工作；分析了间谐波的测量结果，指出由于3个测量点所带的间谐波源负荷不同，所监测到的间谐波成分也各有特点。根据测量结果，指出了IEC61000系列标准在应用中存在的缺陷；并且建议，中国的间谐波标准应该按4个频率段的划分来取不同的间谐波限值。 |

| Abstract: |
| The interharmonic detection equipment is introduced，including the iterative DFT algorithm， hardware and software design，calibration method and experimental results. The concept of“interharmonic record” is presented to measure the interharmonic content of power grid. Practical interharmonic measuring is carried out for three kinds of typical interharmonic sources and the experimental results are analyzed， which shows that different interharmonic sources have different interharmonic components. According to the experimental results，it is pointed out that IEC61000 standards have defects in applications and four frequency intervals should be set and each has its own limit value. |
