【正文】 power system harmonics can cause partial parallel resonant or series resonant, the harmonic content of amplification, resulting in capacitor equipment destroyed。s, due to high voltage DC transmission technology, and lots of papers are published about harmonic problems. EWXimbark in his book have been summarized since the 70s, due to the rapid development of power electronics, various power electronic devices in power systems, industrial, transportation and the family is used widely, the harm caused by harmonics that are also more serious. Countries in the world to give full attention to the harmonic problems, regular meetings of the Colloquium harmonic problems. International Ctrotechnical Commission (IEC) and CIGRE are successively formed a special working group to develop including the power supply system, the electrical equipment and electrical equipment and appliances, including harmonic standards, and harmonic interference included within the scope of electromagnetic patibility. Harmonic problems in China started late, Miss Lu, who actually published in 1988, Power System armonics, a book about the power harmonic problems in our country more influential writings. Harcourt Road, etc. and only published in 1994, HVDC transmission system harmonic analysis and filter is the representation of books published in recent years. Lin Hai Xue, Sun Shuqin, etc., published in 1998, Harmonic power network, a detailed harmonic analysis. In addition, reunification and Yung Tang Jian Gang, who were so independent translation of the J. Atrilaga book Power System Harmonics, which also has great influence at home and abroad .Harmonic study is very significant. First, because the danger is very serious harmonics, harmonic power can the reduction, transmission and use of lower efficiency。附錄2With the development of the power system and the opening of the electricity market，the power quality problem has been received increasing attention. The pollution of the harmonies to the grid increasingly severe，owing to the prevalence of the nonlinear loads(harmonies courses) application. With the development of power system，the power quality is requested to be better and better．Harmonic is the most general phenomenon in power system．And harmonic is the main index of power power system harmonic is one of the most important parameter. With the development of electric power and electron technology, a number of the nonlinear 10ads and all kinds of mutating equipments are widely applied in every walk of life，what they bring a mass of harmonic current make the content of harmonic increase in the power system and quality of power drop．The harmonic affects the safe operation and economic benefit of power supply enterprises to great extent. So, it is urgent to eliminate harmonic. So the harmonic and its suppression technology have being the mon concerning topic worldwide. Harmonic is derived from the acoustic. The mathematical analysis of the harmonics in the 18th century and early 19th century has laid a good foundation. Fourier and other methods proposed by harmonic analysis is still widely used. Power system harmonic problems attract attention early in the 20th century. At that time in Germany, due to the use of mercury arc converter static caused by the voltage and current waveform distortion. In 1945 JC Read published the paper converter harmonics of the early classic papers on the harmonic. To the 5039。在這個(gè)文件中，提出了一種方法來(lái)確定最佳傳輸擴(kuò)展計(jì)劃下的放松管制電力系統(tǒng)。對(duì)傳輸中的擴(kuò)張目標(biāo)放松管制的環(huán)境應(yīng)該從不同的傳統(tǒng)的電力工業(yè)。在放松管制或者電力行業(yè)改革已創(chuàng)造一個(gè)競(jìng)爭(zhēng)開(kāi)放的市場(chǎng)環(huán)境。在另一方面牛頓法生產(chǎn)最快由于其小的迭代次數(shù)的全面解決方案 （小于六個(gè)迭代） 和諾頓等效方法將成為一個(gè)只有 80 多個(gè)諧波時(shí)要考慮，有很好的選擇。 所有方法都計(jì)算非線性注入已計(jì)算的開(kāi)銷電流，但牛頓法雅可比矩陣。電流注入和諾頓等效方法有幾乎相同的計(jì)算開(kāi)銷每個(gè)迭代和一個(gè)考慮諧波的數(shù)目相對(duì)于的線性關(guān)系。這在倍頻，發(fā)射計(jì)劃結(jié)果以及存在的甚至諧波和三次諧波盡管在 TCR 的三角洲連接分支。在接地的選擇在變壓器和諧波過(guò)濾器的缺乏連接是故意的。這是一個(gè)必要的和重要的任務(wù)，特別是在一個(gè)弱系統(tǒng)電壓配置文件可以在其中顯著更改負(fù)載變化。 系統(tǒng)數(shù)據(jù)載列于附件。 銜接，重點(diǎn)是計(jì)算的時(shí)間和魯棒性而非該操作系統(tǒng)的方面。每個(gè) TCR 分支注射在兩個(gè)網(wǎng)絡(luò)的諧波電流節(jié)點(diǎn)，與對(duì)面的跡象。在是從節(jié)點(diǎn)導(dǎo)納構(gòu)建塊對(duì)角矩陣在計(jì)算的系統(tǒng)的低壓與關(guān)聯(lián)矩陣在頻率。 絡(luò)表示電源系統(tǒng)網(wǎng)絡(luò)的線性部分 (進(jìn)口原版)通過(guò)在每個(gè)諧波索取其導(dǎo)納矩陣頻率。 一種可調(diào)諧的并行像在可控串補(bǔ)與線系列中的 LC 電路。射擊控制是基本上與電壓調(diào)節(jié)函數(shù)在被調(diào)整以確保點(diǎn)火延遲通過(guò)更改網(wǎng)無(wú)功功率注入足夠的電壓支持SVC。答： 靜功補(bǔ)償裝置 （SVC）SVC (六脈沖) 的典型配置由組成三個(gè)三角洲連接 TCR 分支與并行接地固定或晶閘管開(kāi)關(guān)電容器。A電力系統(tǒng)的模型基于諧波功率流的模塊化方法在分區(qū)及其線性部分系統(tǒng)的非線性部分 。近年來(lái)，更高的要求已被列入傳輸網(wǎng)絡(luò)及在需求增加將上升由于nonutility發(fā)電機(jī)和越來(lái)越多各公用事業(yè)自己競(jìng)爭(zhēng)加劇。那里很多情況下，經(jīng)濟(jì)的能源或儲(chǔ)備共享是受限于傳輸能力和情況并非越來(lái)越好。諧波研究及其抑制技術(shù)己日益成為人們關(guān)注的問(wèn)題.電力公司被迫經(jīng)營(yíng)系統(tǒng)接近其熱穩(wěn)定性的限制和因主要障礙，例如環(huán)境，偏右的路和電力成本問(wèn)題傳輸網(wǎng)絡(luò)擴(kuò)容。對(duì)電力系統(tǒng)來(lái)說(shuō)，無(wú)諧波就是“綠色”的主要標(biāo)志之一。但是，電力電子裝置產(chǎn)生的諧波污染己經(jīng)成為阻礙電力電子技術(shù)發(fā)展的重大障礙，迫使電力電子領(lǐng)域的研究人員必須對(duì)諧波問(wèn)題進(jìn)行更為有效的研究。諧波還會(huì)引起繼電保護(hù)和自動(dòng)裝置誤動(dòng)作，對(duì)通信設(shè)備產(chǎn)生嚴(yán)重干擾等。使電氣設(shè)備過(guò)熱、產(chǎn)生振動(dòng)和噪聲，并使絕緣老化，使用壽命縮短，甚至發(fā)生故障或燒毀。諧波的研究是很有意義的。世界各國(guó)都對(duì)諧波問(wèn)題給予充分關(guān)注，定期召開(kāi)有關(guān)諧波問(wèn)題的學(xué)術(shù)討論會(huì)。到了50年代和60年代，由于高壓直流輸電技術(shù)的發(fā)展，發(fā)表了大量電力系統(tǒng)諧波問(wèn)題的論文。電力系統(tǒng)的諧波問(wèn)題早在20世紀(jì)的20年代和30年代就引起人們的關(guān)注。有關(guān)諧波的數(shù)學(xué)分析早在18世紀(jì)和19世紀(jì)就己奠定了良好的基礎(chǔ)。因此，諧波及其抑制技術(shù)己成為國(guó)內(nèi)外廣泛關(guān)注的課題。諧波給供電眾業(yè)的安全運(yùn)行和經(jīng)濟(jì)效益帶來(lái)了巨大影響。諧波是目前電力系統(tǒng)中最普遍現(xiàn)象，是電能質(zhì)量的主要指標(biāo)。參考文獻(xiàn)[1] 羅安．電網(wǎng)諧波治理和無(wú)功補(bǔ)償技術(shù)及裝備[M]．北京：中國(guó)電力出版社，2006[2] WAGER V E．Effects of Harmonics on Equipment[J]．IEEE Tram on PD，2000，8(2)：672．680．[3] 張直平．城市電網(wǎng)諧波手冊(cè)[M]．中國(guó)電力出版社，2003：23．54．[4] 王海濤，石剛，張慧琦．電力系統(tǒng)諧波分析[J]．黑龍江電力，2002，24(3)：239．242．[5] 張保會(huì)，尹項(xiàng)根．電力系統(tǒng)繼電保護(hù)[M]．北京：中國(guó)電力出版社，2005.[6] 楊斌文，劉麗英，王文虎．電力系統(tǒng)中的諧波的危害與產(chǎn)生[J]．電氣時(shí)代，2002，2(2)：3031．[7] 王兆安，楊君．諧波抑制和無(wú)功功率補(bǔ)償(第二版)[M]．北京：機(jī)械工業(yè)出版社，2006.[8] 林海雪，孫樹(shù)勤．電力網(wǎng)中的諧波[M]．北京：中國(guó)電力出版社，1998．[9] 吳競(jìng)呂．電力系統(tǒng)諧波[M]．北京：水利電力出版社，1988．[10] 張直平，李芬辰．城市電網(wǎng)諧波手冊(cè)[M]．北京：中國(guó)電力出版社，2001．2．[11] 章健．電力系統(tǒng)負(fù)荷模型與辨識(shí)[M]．北京：中國(guó)電力出版社，2007．[12] 陳冬紅．《電力系統(tǒng)諧波測(cè)量和分析方法研究》[D].附錄1隨著電力系統(tǒng)的發(fā)展以及電力市場(chǎng)的開(kāi)放，電能質(zhì)量問(wèn)題越來(lái)越引起廣關(guān)注。 進(jìn)而研究了電力系統(tǒng)諧波的抑制措施，消除或抑制諧波的對(duì)策,可以有效地減小諧波對(duì)電網(wǎng)的影響，以消除和防止諧波的影響。為了有效補(bǔ)償和一種負(fù)荷產(chǎn)生諧波電流，首先對(duì)諧波的成分有精確認(rèn)識(shí)，因而需要實(shí)時(shí)檢測(cè)負(fù)載電流中的諧波。也就是說(shuō)來(lái)自發(fā)電設(shè)備和用電設(shè)備。一方面，用戶需要電力部門公共電網(wǎng)電能質(zhì)量能確保用戶正常生產(chǎn)用電；另一方面，電力部門也要求用戶的生產(chǎn)用電不影響公共電網(wǎng)的正常供電，特別是對(duì)于一些會(huì)對(duì)公必電網(wǎng)電能質(zhì)量造成睡大影響的大型用戶，從源頭上進(jìn)行電能質(zhì)量的治理是必須的。電力諧波的定量計(jì)算，一方面方便用戶采取措施降低諧波影響，另一方面供電部門可以確定諧波源。但在電網(wǎng)畸變或不對(duì)稱時(shí):p、q檢測(cè)方法存在誤差，iq、iq檢測(cè)方法只取sin硯和一cos硯，畸變電壓的諧波成分在運(yùn)算過(guò)程中不出現(xiàn)，因而檢測(cè)結(jié)果不受影響，檢測(cè)結(jié)果準(zhǔn)確。這是采用p、q運(yùn)算方式的固有缺點(diǎn)。采用p、q運(yùn)算方式和ip一iq運(yùn)算方式檢測(cè)到的諧波分量、:由仿真結(jié)果可以看出，采用p、q運(yùn)算方式所得到的基波分量i是不準(zhǔn)確的。當(dāng)a、b、c三相電壓幅值不相等。因此研究電網(wǎng)電壓波形畸變時(shí)對(duì)檢測(cè)方法的影響是很有意義的。2)電網(wǎng)電壓波形有畸變時(shí)理想電網(wǎng)電壓波形應(yīng)為正弦波，但實(shí)際電網(wǎng)電壓波形由于不同的原因會(huì)有一定的畸變，而且這種畸變?cè)谝欢ㄏ薅纫詢?nèi)允許存在。iq運(yùn)算方式檢測(cè)到的諧波分量的波形也相同。 三相對(duì)稱且電網(wǎng)電壓為正炫時(shí)檢測(cè)方法的仿真波形 Simulation waveform of three phase symmetry sine voltage
