產(chǎn)品詳情
The ideal voltage and current wavebs in power systems are all sine waves with a frequency of 50Hz, but they arewidely used in non-linear power equipment (such as high-power thyristors, frequency converters, UPS, switching powersupplies, mid-frequency furnaces, and energy-saving lamps), in which a large number of distorted harmonic currents aregenerated and harmonic currents are coupled to produce harmonic voltages on the line. The Fourier series decombis perbed on the non-sinusoidal distortion current, where the component of the same frequency with the powerfrequency is the fundamental wave, and the component of the integral multiple of the fundamental wave frequency is theharmonic wave. This kind of harmonic "pollution" will cause great harm to the power grid and the user, so the harmonicsuppression is called a "green project"!
由于電力電子技術(shù)的發(fā)展，有源電力濾波器（APF）開始規(guī)?；瘧?yīng)用，相對于傳統(tǒng)的諧波抑制和無功補償裝置，APF 響應(yīng)速度快、實時跟蹤補償各次諧波，具有補償諧波、無功補償和平衡三相電流的功能，同時，APF 還具有不受系統(tǒng)阻抗影響、無諧振隱患、補償效率高等優(yōu)勢，在各行各業(yè)的供電系統(tǒng)中已經(jīng)得到廣泛應(yīng)用。產(chǎn)品符合企業(yè)標準 Q31/0114000129C033-2017《ANAPF 有源電力濾波器》的規(guī)定。
1.2 ANAPF 的基本原理
ANAPF 系列有源電力濾波器并聯(lián)在含諧波負載的低壓配電系統(tǒng)中，能夠?qū)討B(tài)變化的諧波電流進行快速實時的跟蹤和補償。其原理為：ANAPF 系列有源電力濾波器通過 CT 采集系統(tǒng)諧波電流，經(jīng)控制器快速計算并提取各次諧波電流的含量，產(chǎn)生諧波電流指令，通過功率執(zhí)行器件產(chǎn)生與諧波電流幅值相等方向相反的補償電流，并注入電力系統(tǒng)中，從而抵消非線性負載所產(chǎn)生的諧波電流。
