style="text-indent:25px">諧波保護(hù)器的主要用途是吸收諧波，同時(shí)補(bǔ)償基波無(wú)功。電容補(bǔ)償器加電感線圈防止諧波的原理，電感和電容維持一定的比例就可以濾去不同頻率的諧波。電容器串電抗后形成一個(gè)串聯(lián)揩振回路，在諧振頻率下呈現(xiàn)很低的阻抗（理論上為0），如果串聯(lián)諧振頻率與電網(wǎng)諧波保護(hù)器特征諧波頻率一致，則成為純?yōu)V波回路，如果只吸收少量諧波，則稱為失諧濾波回路。失諧濾波回路的主要用途是防止諧波放大，濾波效果不大，回路傳串聯(lián)諧振頻率通常低于電網(wǎng)的蕞低次特征諧波頻率，即設(shè)定為基波頻率的3.8~4.2倍。工程計(jì)算公式為：電抗器電抗XL=電容器容抗XC的百分比（X%），或者：電抗器功率QL=電容器基波容量QC的百分比（X%），電抗器電抗或容量一般為電容器容抗或容量的6~7%。在選擇x=6%時(shí)，諧振次數(shù)為vr=4.08。失諧濾波回路只吸收少量5次及以上的諧波，諧波源產(chǎn)生的諧波的大部分流入電網(wǎng)，電容器容量根據(jù)預(yù)計(jì)達(dá)到的功率因數(shù)值確定。</p><p style="text-indent:25px">“諧波”一詞起源于聲學(xué)。電力系統(tǒng)的諧波問(wèn)題早在20世紀(jì)20年代和30年代就引起了人們的注意。當(dāng)時(shí)在德國(guó)，由于使用靜止汞弧變流器而造成了電壓、電流波形的畸變。1945年J.C.Read發(fā)表的有關(guān)變流器諧波的論文是早期有關(guān)諧波研究的經(jīng)典論文。諧波的定義諧波 (harmonic wave)可以分為電壓諧波和電流諧波，從嚴(yán)格的意義來(lái)講，諧波是指電流中所含有的頻率為基波的整數(shù)倍的電量，一般是指對(duì)周期性的非正弦電量進(jìn)行傅里葉級(jí)數(shù)分解，其余大于基波頻率的電流產(chǎn)生的電量。諧波保護(hù)器是一種常見(jiàn)的機(jī)械設(shè)備。</p><div
