摘要
随着电力电子装置的日益普及和大量应用,电力电子装置产生的谐波已成为电网的主要谐波污染源,其无功问题也很严重。因此,如何消除谐波污染并提高功率因数,已成为现代电力系统中的一个重大课题。有源电力滤波器(APF)、静止无功发生器(SVG) 等作为新一代的谐波抑制与无功补偿装置,其控制系统相当复杂,通常可划分为信号检测、稳定控制和底层驱动控制三大部分。本文结合现有的各种控制及检测方法对这三部分进行了较为全面的分析,并在此基础上对其发展趋势进行论讨。
The harmonics generated by power electronic equipments have become the major source of harmonic with their ever wlclely used in power systems, in the meantime, the problem of reactive power in electronic equipments is also fairly serious. Hence, it is a great task for utilities to eliminate the harmonic and improve the power factor. As new generation devices for harmonic suppression and reactive power compensation, Active Power Filter and Static Var Generators＇control system are complicated. In this paper,different control and detect methods used in these equipments are firstly reviewed, and then the development tendency of them are analyzed.
