有源电力滤波器控制技术现状及发展

Active Power Filter Control Technology Status and Development

伴随着电力电子技术的飞速发展以及广泛应用,在提高输电效率的同时,其带来的弊端也日益凸显,最严重的是造成了电网中的谐波污染,对电力系统的运行、电能的生产及输送都造成很大的危害。现如今治理谐波最有效的方法之一就是使用有源电力滤波器对谐波电流进行补偿。该文对有源电力滤波器的工作原理、分类、控制技术现状以及应用前景进行阐述。

With the rapid development of power electronics and its widespread application, while improving the efficiency of power transmission, its drawbacks have also become increasingly evident, the most serious of which is the harmonic pollution in the power grid, causing great harm to the operation of the power system,the production and transmission of electricity. One of the most effective ways to manage harmonics today is to use active power filters to compensate for harmonic currents. In this paper, the working principle, classification,current status of control technology and application prospects of active power filters are described.
