Power Supply and Distribution System ABSTRACT: 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 daily-life. For the electric power, allcostumers expect to pay the lowest price for the highest reliability, but dont consider that its self-contradictory in the co-existence of economy and improve the reliability of the power supply network, we must increase the investment cost of the network construction 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 power-off 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 power-off. KEYWORDS: power supply and distribution, power distribution reliability，reactive compensation, load distribution The revolution of electric power system has brought a new big round construction,which is pushing the greater revolution of electric power technique along with the application of new technique and advanced equipment. Especially, the combination of the information technique and electric power technique, to great ex- tent, has improved reliability on electric quality and electric supply. The technical development decreases the cost on electric construction and drives innovation of electric network. On the basis of national and internatio- nal advanced electric knowledge, the dissertation introduces the research hotspot for present electric power sy- etem as following. Firstly, This dissertation introduces the building condition of distribution automation(DA), and brings forward two typical construction modes on DA construction, integrative mode and fission mode .It emphasize the DA structure under the condition of the fission mode and presents the system configuration, the main station scheme, the feeder scheme, the optimized communication scheme etc., which is for DA research reference. Secondly, as for the (DA) trouble measurement, position, isolation and resume, This dissertation analyzes the changes of pressure and current for line problem, gets math equation by educing phase short circuit and problem position under the condition of single-phase and works out equation and several parameter s U& , s I& and e I& table on problem . It brings out optimized isolation and resume plan, realizes auto isolation and network reconstruction, reduces the power off range and time and improves the reliability of electric power supply through problem self- diagnoses and self-analysis. It also introduces software flow and use for problem judgement and sets a model on network reconstruction and computer flow. Thirdly, electricity system state is estimated to be one of the key techniques in DA realization. The dissertation recommends the resolvent of bad measurement data and structure mistake on the ground of describing state estimate way. It also advances a practical test and judging way on topology mistake in state estimate about bad data test and abnormity in state estimate as well as the problem and effect on bad data from state measure to state estimate .As for real time monitor and control problem, the dissertation introduces a new way to solve them by electricity break and exceptional analysis, and the way has been tested in Weifang DA.Fourthly, about the difficulty for building the model of load forecasting, big parameter scatter limit and something concerned, the dissertation introduces some parameters, eg. weather factor, date type and social environment effect based on analysis of routine load forecasting and means. It presents the way for electricity load forecasting founded on neural network(ANN),which has been tested its validity by example and made to be good practical effect. Fifthly, concerning the lack of concordant wave on preve nting concordant wave and non-power compensation and non-continuity on compensation, there is a topology structure of PWM main circuit and nonpower theory on active filter the waves technique and builds flat proof on the ground of Saber Designer and proves to be practical. Meanwhile, it analyzes and designs the way of non-power need of electric network tre- nds and decreasing line loss combined with DA, which have been tested its objective economic benefit throu- gh counting example. Sixthly, not only do the dissertation design a way founded on the magrginal electric price fitted to our present national electric power market with regards to future trends of electric power market in China and fair trade under the government surveillance, that is group competitio n in short-term trade under the way of grouped price and quantity harmony, but also puts forward combination arithmetic, math model of trading plan and safty economical restriction. It can solve the original contradiction between medium and long term contract price and short term competitive price with improvement on competitive percentage and cut down the unfair income difference of electric factory, at the same time, it can optimize the electric limit for all electric factories and reduce the total purchase charge of electric power from burthen curve of whole electric market network. The distribution network is an important link among the power system. Its neutral grounding mode and operation connects security and stability of the power system directly. At the same time, the problem about neutral grounding is associated with national conditions, natural environment, device fabrication and operation. For example, the activity situation of the thunder and lightning, insulating structure and the peripheral interference will influence the choice of neutral grounding mode Conversely, neutral grounding mode affects design, operation, debugs and developing. Generally in the system higher in grade in the voltage, the insulating expenses account for more sizable proportion at the total price of the equipment. It is very remarkable to bring the economic benefits by reducing the insulating level. Usually such system adopt the neutral directly grounding and adopt the autoreclosing to guarantee power supply reliability. On the contrary, the system which is lower in the voltage 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 篇三：某花园洋房配电及照明系统设计英文翻译成绩： 西安 xxxxx大学 xx学院 毕业设计 (论文)英文翻译 院 （系）： 机械电子工程系 专业班级：自动化 0802 毕 业 设 计 论 文 方 向 ：某花园洋房配电及照明系统设计 ：电气装置安装设计与施工 翻 译 文 章 题 目 学生姓名： xxxxxxx 学 号：xxxxxxxxxxxxx 指导教师：xxxxxx XX 年 4月 13日 电气装置安装设计与施工 1.照明设计和照明装置施工 一般规定 （1）当在砖石结构中安装电气照明装置时，应采用预埋吊钩、螺栓、螺钉、膨胀螺栓、尼龙塞或塑料塞固定；严禁使用木楔。当设计无规定时，上述固定件的承载能力应与电气照明装置的重量相匹配。 （2）在危险性较大及特殊危险场所，当灯具距地面高度小于时，应使用额定电压为 36V及以下的照明灯具，或采取保护措施。 （3）电气照明装置的接线应牢固，电气接触应良好；需接地或接零的灯具、开关、插座等非带电金属部分，应有明显标志的专用接地螺钉。 灯具 （1）灯具不得直接安装在可燃构件上；当灯具表面高温部位靠近可燃物时，应采取隔热、散热措施。 （2）在变电所内，高压、低压配电设备及母线的正上方，不应安装灯具。 （3）灯头的绝缘外壳不应有破损和漏电。 （4）对带开关的灯头，开关手柄不应有裸露的金属部分。 插座 （1）插座的安装高度应符合设计的规定，当设计无规定时，应符合下列要求。 （2）距地面高度不宜小于托儿所、幼儿园及小学校不宜小于；同一场所安装的插座高度应一致。 （3）车间及试验室的插座安装高度距地面不宜小于；特殊场所暗装的插座不应小于；同一室内安装的插座高度差不宜大于 5mm；并列安装的相同型号的插座高度差不宜大于 1mm。 （4）落地插座应具有牢固可靠的保护盖板。 （5）插座的接线应符合下列要求： 单相两孔插座，面对插座的右孔或上孔与相线相接，左孔或下孔与零线相接；单相三孔插座，面对插座的右孔与相线相接，左孔与零线相接。单相三孔、三相四孔及三相五孔插座的接地线或接零线均应接在上孔。插座的接地端子不应与零线端子直接连接。 （6）当交流、直流或不同电压等级的插座安装在同一场所时，应有明显的区别，且必须选择不同结构、不同规格和不能互换的插座；其配套的插头，应按交流、直流或不同电压等级区别使用。 （7）同一场所的三相插座，其接线的相位必须一致。（8）备用照明、疏散照明的回路上不应设置插座。 开关 （1）安装在同一建筑物、构筑物内的开关，宜采用同一系列的产品，开关的通断位置应一致，且操作灵活、接触可靠。 （2）开关安装的位置应便于操作，开关边缘距门框的距离宜为；开关距地面高度宜为；拉线开关距地面高度宜为 23m，且拉线出口应垂直向下。 （3）相线应经开关控制；民用住宅严禁装设床头开关。 照明配电箱（板） （1）照明配电箱（板）内的交流、直流或不同电压等级的电源，应具有明显的标志。 （2）照明配电箱（板）不应采用可燃材料制作；在干燥无尘的场所，采用的木制配
