摘要
随着电力电子技术的发展,电力电子装置得到了广泛应用。然而,在应用这些设备的同时,它们向电网注入了大量谐波,使电网电能质量受到严重污染。对电力系统谐波产生的原因及其带来的危害进行了阐述,详细介绍了现有的谐波抑制方法,并对各种方法优缺点进行了比较分析。最后,对谐波抑制技术的未来发展趋势进行了展望。
With the development of power electronic technology,power electronic equipments have been broadly applied.However,their applications bring a great deal of harmonics to power net and degrade power quality seriously.The causes of creating harmonics and their harms are elucidated;existing harmonic suppression methods are introduced in detail;their advantages and disadvantages are compared.Besides,the development tendency of harmonic suppression technique is prospected.
