| 摘 要： | 在滤波过程中,滤波装置容易与配电网之间产生参数匹配,造成谐波放大,危及电网的正常运行。因此,在设计滤波方案时,应抑制谐波放大。研究了产生谐波放大的原因,建立了分析谐波放大的模型,分析了滤波支路的谐波放大特性和谐振特性,并提出了滤波装置的改进措施。同时的实际应用中可通过适当选择滤波支路中电抗器的电抗率来减小或避免产生谐波放大。在实际工程中,得到较好的应用,经实测效果较为理想。

| Abstract: | During the process of filtering harmonics,filter devices mutually match with the distribution network parameter and enlarge harmonics,which will endanger the normal operation of power network.For the design of the filter,harmonic enlargement should be avoided.This article researched the cause of harmonic enlargement,built the model of harmonic enlargement,analyzed the harmonic enlargement characteristics and resonance characteristics of filters,and proposed an improvement measure for the filter device.Harmonic enlargement can be minished or avoided by properly choosing the reactance rate of reactor in the spur track of filters.It was implemented in some projects and the effect was ideal. |
