tage adopts neutral none grounding to raise power supply reliability. So it is an important subject to make use of new type earth device to apply to the distribution network under considering the situation in such factors of various fields as power supply reliability, safety factor, overvoltage factor, the choice of relay protection, investment cost, (論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川The main work of this paper is to research and choice the neutral grounding mode of the l0kV distribution network. The neutral grounding mode of the l0kV network mainly adopts none grounding, grounding by arc suppressing coil, grounding by reactance grounding and directly grounding. The best grounding mode is confirmed through the technology parison. It can help the network run in safety and limit the earth electric arc by using autotracking pensate device and using the line protection with the detection of the sensitive small ground current. The paper introduces and analyzes the characteristic of all kind of grounding modes about l0kV network at first. With the parison with technological and economy, the conclusion is drawn that the improved arc suppressing coil grounding mode shows a very big development (論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川Then, this paper researches and introduces some operation characteristics of the arc suppressing coil grounding mode of the l0kV distribution network. And then the paper put emphasis on how to extinguish the earth electric arc effectively by utilizing the resonance principle. This paper bines the development of domestic and international technology and innovative achievement, and introduces the puter earth protection and autotracking pensate device. It proves that the improved arc suppressing coil grounding mode have better operation characteristics in power supply reliability, personal security, security of equipment and interference of munication. The application of the arc suppressing coil grounding mode is also researched in this (論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川Finally, the paper summarizes this topic research. As a result of the domination of the arc suppressing coil grounding mode, it should be more popularized and applied in the distribution network in the way of thinking, project and conclusions in this thesis have effect on the research to choose the neutral grounding mode not only in I0kV distribution network but also in other power system..電氣開題報告與外文翻譯三江學(xué)院畢業(yè)設(shè)計(論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川The basic function of the electric power system is to transport the electric power towards customers. The l0kV electric distribution net is a key point that connects the power supply with the electricity using on the industry, business and dailylife. For the electric power, all costumers expect to pay the lowest price for the highest reliability, but don39。為lOkV配電網(wǎng)的規(guī)劃設(shè)計及為建成網(wǎng)架堅實、布局合理、管理科學(xué)、能夠安全、優(yōu)質(zhì)、高效運行的配電網(wǎng)提供理論的依據(jù)和有益的指引。而后對配電網(wǎng)各種接線模式的可靠性和經(jīng)濟(jì)性進(jìn)行了計算和分析,通過計算并描繪的各種圖表。通過計算電網(wǎng)的投資和用戶停電的損失,最終可找到一個平衡點,使投資和損失的綜合經(jīng)濟(jì)性最優(yōu)。對于所有用戶都期望以最低的價格買到具有高度可靠性的電能。隨著電網(wǎng)的不斷發(fā)展和豐富的實踐結(jié)果表明,以諧振接地方式為代表的小電流接地方式優(yōu)于其他接地方式,這是配電網(wǎng)的中性點接地方式發(fā)展的總趨勢,在今后的配電網(wǎng)接地方式中應(yīng)推廣應(yīng)用。接著,本文結(jié)合國內(nèi)外科技的發(fā)展和創(chuàng)新成果,對諧振接地優(yōu)化方式中的微機接地保護(hù)性和自動跟蹤補償裝置進(jìn)行全面的分析與論述,說明諧振接地優(yōu)化方式在供電可靠性、人身安全、設(shè)備安全和通信干擾等方面,具有較好的運行特性,既解決了小電流接地系統(tǒng)接地保護(hù)的選擇性,又實現(xiàn)了自動調(diào)諧,使此種接地方式成為配電網(wǎng)比較理想的中性點接地方式。本文首先對配電網(wǎng)各類接地方式做深入的研究。因此,在綜合考慮供電可靠性、安全因素、過電壓因素、繼電保護(hù)的選擇、投資費用等各方面因素的情況下,來論證正確選擇配電網(wǎng)接地方式的重要性,以及如何不斷開發(fā),利用新型接地裝置來應(yīng)用在配電網(wǎng)接地系統(tǒng)中是當(dāng)今配電網(wǎng)接地方式的一個重要課題。 (論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川(3)(論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川(4)(論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯下燙品適耘禱憫楷鎳簽算矢簾锨深剃撤轉(zhuǎn)贓昧晰姻朔掂朗川(5)針對無源濾波在抑制諧波和無功補償方面的不足以及補償度的不連續(xù)性本文提出了一種PWM 主電路拓樸結(jié)構(gòu)和基于無功功率理論的有源濾波方案建立了基于Saber Designer (論文)開題報告題 目110kV變電站電氣部分設(shè)計學(xué)生姓名、學(xué)號江杰迪B08071109專業(yè)電氣工程及其自動化指導(dǎo)教師姓名張俊芳職稱副教授應(yīng)包括課題研究的背景、意義、文獻(xiàn)綜述;課題研究的基本內(nèi)容、重點難點及要解決的主要問題;查樂臘孩燈口朔染弧械籃繭撩丘陜粗腸署娃樁貓銘雛辛煩落令臍論鄲喬塊活嫩臍棲稗湯
