摘要
作为工业生产的设备驱动器通用变频器已经被普遍应用,伴随其诸多优点而来的是作为电子电力设备的通用变频器也给电网带来了严重的谐波污染。所以解决其对电网的谐波影响问题也随之被人们关注,尤其是变频器生产厂家。深入分析变频器整流侧谐波产生的机理,为了减少谐波污染并在此基础上通过仿真研究和实物实验给出一个简洁实用的关于变频器的交流电抗器选择的公式。
Now, general purpose converter is widely used in industry, harmonic pollution caused by it is increasingly worsening the quality of power grid. The problem is paid attention to, especially converter manufacturers. For improving this serious problem, by simulating, the harmonics by modeling the rectifier in system was investigated in depth, through which the relationship between the inserting inductance and harmonics fed to the power grid was presented. From the theoretical analysis and result of the simulation, a simple and practical formula of the inductor with the optimum parameter was introduced, to reduce the harmonics feeding into the power grid.
