<P align=right>徐霜</P> <P align=right>安科瑞電氣股份有限公司</P> <P> <STRONG>摘要：</STRONG>本文介紹了ANAPF有源濾波裝置的工作原理、方案、技術(shù)參數(shù)以及產(chǎn)品特點(diǎn)，結(jié)合在江蘇某知名紡織企業(yè)低壓配電系統(tǒng)中的應(yīng)用案列，說明了有源濾波裝置在低壓配電系統(tǒng)中對改善供電電能質(zhì)量、治理諧波起到了至關(guān)重要的作用。</P> <P> <STRONG>引言 </STRONG></P> <P> 隨著電力電子變流裝置的應(yīng)用日益廣泛，電能得到了更加充分的利用。但非線性電力裝置設(shè)備的廣泛應(yīng)用產(chǎn)生了大量畸變的電流諧波，畸變電流在電網(wǎng)中的流動導(dǎo)致了諧波電壓；諧波污染越來越多地威脅到電力系統(tǒng)安全、穩(wěn)定、經(jīng)濟(jì)運(yùn)行，給同一網(wǎng)絡(luò)的線性負(fù)載和其它用戶帶來了極大影響。諧波已與電磁干擾、功率因數(shù)降低并列為電力系統(tǒng)的三大公害。所以了解諧波產(chǎn)生的原理、研究消除供配電系統(tǒng)中的高次諧波問題對改善供電質(zhì)量和確保電力系統(tǒng)安全經(jīng)濟(jì)運(yùn)行有著非常積極的意義。諧波測量是諧波問題中的一個重要分支，對抑制諧波、解決諧波產(chǎn)生的問題有著重要的指導(dǎo)作用。因此對諧波的測量和分析是電力系統(tǒng)分析和控制中的一項(xiàng)重要工作，是繼電保護(hù)、故障測量等工作開展的重要前提。</P> <P> <STRONG>1.工作原理</STRONG></P> <P> ANAPF系列有源電力濾波裝置并聯(lián)在含諧波負(fù)載的低壓配電系統(tǒng)中，能夠?qū)討B(tài)變化的諧波電流進(jìn)行快速實(shí)時(shí)的跟蹤和補(bǔ)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(jì)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(bǔ)償電流，并注入電力系統(tǒng)中，從而抵消非線性負(fù)載所產(chǎn)生的諧波電流。</FONT></P> <P style="PADDING-RIGHT: 0px;
