Analysis of Method for Current Control Used in APF of Parallel Type

伴随着我国的电子科技技术的飞跃发展与我国电力电子方面设备的更新换代,使得我国的电器谐波产生加大,这些设备所产生的大量谐波会对电网产生极大的不可逆的损害,为了抑制电气设备谐波的产生,有源电力滤波器成为了一种先进有效的能够及时动态抑制谐波产生的装置,有源电力滤波器还可以做到对于无功效果的补偿。本文着重于分析有源电力滤波器的电流控制方法,从有源电力滤波器的基础工作原理入手,分析有源电力滤波器与电网连接形成有效数学模型并对于直流侧母线电压等数值进行选取与分析。

The rapid development and progress of electronic science and technology, as well as the updating and renewing of equipment related to electricity and electronics in China trigger the sudden and considerable generation of electrical harmonies, moreover, these great deal of electrical harmonies generated in equipment will bring great irreversible damages to the power grid. In this regard, to inhibit such harmonies from the origin, APF has become the device which is advanced and effective to inhibit the generation of harmonies in a timely manner, with another function to realize compensation for reactive power. The paper highlights on the analysis of method for current control used in APF by starting from the basic working principle of APF, then, it elaborates the effective mathematical model formed after the connection of APF and power grid, as well as selects and analyzes the DC bus voltage and other values.
