【正文】 c 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。t consider that it39。s selfcontradictory in the coexistence of economy and reliable. To improve the reliability of the power supply network, we must increase the investment cost of the network con struction But, if the cost that improve the reliability of the network construction, but the investment on this kind of construction would be worthless if the reducing loss is on the poweroff is less than the increasing investment on improving the reliability .Thus we find out a balance point to make the most economic, between the investment and the loss by calculating the investment on power net and the loss brought from poweroff. The thesis analyses on the economic and the reliable of the various line modes, according to the characteristics various line modes existed in the electric distribution net in foshan..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First, the thesis introduces as the different line modes in the l0kV electric distribution net and in some foreign countries. Making it clear tow to conduct analyzing on the line mode of the electric distribution net, and telling us how important and necessary that analyses （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Second, it turns to the necessity of calculating the number of optimization subsection, elaborating how it influences on the economy and reliability. Then by building up the calculation mode of the number of optimization subsection it introduces different power supply projects on the different line modes in brief. Third, it carries on the calculation and analyses towards the reliability and economy of the different line modes of electric distribution net, describing drafts according by the calculation. Then it makes analysis and discussion on the number of optimization （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At last, the article make conclusion on the economy and reliability of different line modes, as well as, its application situation. Accordion to the actual circumstance, the thesis puts forward the beneficial suggestion on the programming and construction of the l0kV electric distribution net in all areas in foshan. Providing the basic theories and beneficial guideline for the programming design of the lOkV electric distribution net and building up a solid net, reasonable layout, qualified safe and efficientlyworked electric distribution （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
