概述 Overview

有源电力滤波器 (APF) 是基于 IGB 功率变换器的用于动态消除谐波、动态补偿无功的电力电子装置。APF 实时检测电网中的各次谐波和无功，并进行动态跟
踪补偿，因此能够对幅值和频率都变化的谐波和变化的无功进行补偿。APF 直挂式有源电力滤波器采用闭环控制方式，并结合独创的自适控制算法，使 APF
在满载和轻载下均能达到很好的滤波特性；APF 直挂式有源电力滤波器采用电流平均值控制方式并结合 LCL 拓扑结构，克服了传统的滞环电流控制由于开关
频率变化所带来的输出频谱范围宽、滤波较困难、高频谐波干扰电网等缺点。 最新小型柜
Active power filter (APF) is based on IGB power converter for the dynamic elimination of harmonics, dynamic compensation reactive power electronic devices. APF
real-time detection of the harmonics and reactive power in the power grid, and dynamic tracking compensation, so the amplitude and frequency can change the
harmonics and changes in reactive power compensation. APF plug-in active power filter using closed-loop control mode, combined with the original self-adaptive
control algorithm, so that APF in full load and light load can achieve a good filter characteristics; APF plug-in active power filter Current mean control mode and
combined with LCL topology, overcomes the shortcomings of the traditional hysteresis current control due to the switching frequency change caused by the output
spectrum range, filtering more difficult, high frequency harmonic interference power grid and other shortcomings.

产品特点及应用 Product features and applications

现代工业的高速发展使得各种非线性和时变性电力电子装置得到大规模使用，电力系统中谐波成份显著增加，“谐波污染”已经成为影响电能质量的主要因
素之一。
从工作原理来分，产生谐波的谐波源主要有三类： 低压开关柜
The rapid development of modern industry makes a variety of non-linear and time-varying power electronic devices have been large-scale use, power system
harmonic components increased significantly, "harmonic pollution" has become one of the main factors affecting the quality of power.
From the working principle to points, there are three main harmonic sources of harmonic:

铁磁饱和型 Ferromagnetic saturation type 电缆分支箱、元件及配电系统
变压器、电抗器、互感器等。这些带铁心的电力设备，其铁芯饱和电流、励磁电流及在投入或电压恢复时的励磁涌流都是非正谐波。
Transformers, reactors, transformers and so on. These core power equipment, the core saturation current, excitation current and in the input or voltage recovery
when the inrush current is non-harmonic.

电子开关型 Electronic switch type
整流器、逆变器及可控硅开关设备等。冶金、电气化机车等企业，以及家用电器、节能灯具和电力系统直流输电等都是谐波源。特征谐波主要与整流器的脉
动数相关，6 脉动整流器产生 6K=1 次谐波，12 脉动产生 12K+1 次谐波。
Rectifier, inverter and thyristor switching equipment. Metallurgy, electrification locomotives and other enterprises, as well as household appliances, energy-saving
lamps and power systems, such as DC transmission are harmonic sources. The characteristic harmonics are mainly related to the number of pulses of the rectifier.
The 6-pulse rectifier produces 6K = 1st harmonic and 12 pulses produce 12K + 1st harmonic.
电力总包工程
电弧型 Arc type
炼钢炉、金属熔化设备、电焊机群等。谐波随设备工作状态而变化。
Steelmaking furnace, metal melting equipment, welding group and so on. Harmonics vary with the operating status of the device.
