除傳統(tǒng)的LC調(diào)試濾波器目前還在應(yīng)用外，當(dāng)前抑制諧波的一個(gè)重要趨勢(shì)是采用有源電力濾波器，它串聯(lián)或是并聯(lián)于主電路中，實(shí)時(shí)從補(bǔ)償對(duì)象中檢測(cè)出諧波電流，由補(bǔ)償裝置產(chǎn)生一個(gè)與該諧波電流大小相等、方向相反的補(bǔ)償電流，從而使電網(wǎng)電流只含基波電流。這種濾波器能對(duì)頻率和幅值都變化的諧波進(jìn)行跟蹤補(bǔ)償，其特性不受系統(tǒng)的影響，無諧波放大的危險(xiǎn)，因而倍受關(guān)注，在日本等國已獲得廣泛應(yīng)用。GE SPEEDTRONIC MP DAUGHTER BOARD DS3800DMPK 1E1DGENERAL ELECTRIC DS3800HPLA1B1C USPP DS3800HPLA1B1CGENERAL ELECTRIC DS3800NHVD1C1B USPP DS3800NHVD1C1BGENERAL ELECTRIC DS3800NHVD1D1B USPP DS除傳統(tǒng)的LC調(diào)試濾波器目前還在應(yīng)用外，當(dāng)前抑制諧波的一個(gè)重要趨勢(shì)是采用有源電力濾波器，它串聯(lián)或是并聯(lián)于主電路中，實(shí)時(shí)從補(bǔ)償對(duì)象中檢測(cè)出諧波電流，由補(bǔ)償裝置產(chǎn)生一個(gè)與該諧波電流大小相等、方向相反的補(bǔ)償電流，從而使電網(wǎng)電流只含基波電流。這種濾波器能對(duì)頻率和幅值都變化的諧波進(jìn)行跟蹤補(bǔ)償，其特性不受系統(tǒng)的影響，無諧波放大的危險(xiǎn)，因而倍受關(guān)注，在日本等國已獲得廣泛應(yīng)用。GE SPEEDTRONIC MP DAUGHTER BOARD DS3800DMPK 1E1DGENERAL ELECTRIC DS3800HPLA1B1C USPP DS3800HPLA1B1CGENERAL ELECTRIC DS3800NHVD1C1B USPP DS3800NHVD1C1BGENERAL ELECTRIC DS3800NHVD1D1B USPP DS3800NHVD1D1BGENERAL ELECTRIC DS3800HROA1A1A NSFP DS3800HROA1A1AGENERAL ELECTRIC DS3800NGRC1H1F REGULATOR BOARD C-ESSGENERAL ELECTRIC DS3800NHVF11B1A USPP DS3800NHVF11B1AGeneral Electric DS3800DMPK1B1B Circuit Board USEDGeneral Electric DS3800HSHA1D1D Circuit Board USEDGENERAL ELECTRIC DS3800HDDD USPP DS3800HDDDGeneral Electric DS3800NADA1E1F Circuit Board U3800NHVD1D1BGENERAL ELECTRIC DS3800HROA1A1A NSFP DS3800HROA1A1AGENERAL ELECTRIC DS3800NGRC1H1F REGULATOR BOARD C-ESSGENERAL ELECTRIC DS3800NHVF11B1A USPP DS3800NHVF11B1AGeneral Electric DS3800DMPK1B1B Circuit Board USEDGeneral Electric DS3800HSHA1D1D Circuit Board USEDGENERAL ELECTRIC DS3800HDDD USPP DS3800HDDDGeneral Electric DS3800NADA1E1F Circuit Board U
