摘要

工业电力系统中由几千赫兹(1 ..近年来,特别是在大部分负载由电力电子组成的装置中,20 kHz)叠加到基波上变得越来越重要。给出了测量结果以及作者研究的几个扰动实例。这些干扰的影响范围很广,如电子办公设备的故障,电源单元损坏,或不可接受的噪音。本文讨论了引入特殊滤波器或附加阻尼等缓解措施。讨论了不同解决方案的具体问题和局限性,并提供了示例

Measures for the limitation of voltage distortion in the kHz range
Disturbances in industrial power systems due to oscillations of several kilohertz (1 .. 20 kHz) superimposed to the fundamental became more and more important in recent years especially in installations where the majority of the load consists of power electronics. Measurement results as well as examples from several cases of disturbances investigated by the authors is presented. The effects of these disturbances vary in a wide range such as malfunction of electronic office equipment, blown power supply units, or unacceptable noise. The paper discusses mitigation measures to solve such problems such as introducing special filters or additional damping. Specific problems and limitations of different solutions is addressed and examples provided
