摘 要 随着人们得居住条件得不断改善,人们对小区电力供应得要求越来越高,特别就是供电得可靠性与持续性。这就要求在进行供配电系统设计时要结合该小区得规模与规模标准来设计,要既能满足小区得用电负荷,又能保证小区得供电安全及供电可靠性。 本次设计课题内容为某小区 10KV 供配电系统设计。论文得主体结构为:首先论述了课题得意义与设计概况,主要包含此小区供配电系统得设计理论。设计前期根据民用住宅建筑物得负荷计算准则来进行负荷计算,运用了三种负荷计算方法对各类别得用电负荷进行计算与统计,经过分析选择低压集中无功补偿方式,采纳并联电容器,使功率因数由 0、85 提高到 0、932,大大降低了设备运行得损耗;再采纳标幺值法对短路电流进行运算,选择主要电气设备得型号与参数,灵活将电器设备得原理进行理解及运用,根据数据表,选择了合适得电缆型号与截面。后期则从防直击雷与接地系统得角度,对建筑物进行防雷保护得设计,及图纸得绘制。关键词:供配电系统;短路计算;无功补偿ABSTRACT With the continuous improvement of people's living conditions, people's demand for residential power supply is increasingly high, especially the reliability and continuity of power supply、 This requires the design of power supply and distribution system to bine the size and scale of the district standards to design, to both meet the district's electricity load, but also to ensure that the district's power supply security and reliability、 This design topic for the residential area 10KV power supply and distribution design、 The main structure of the thesis is as follows: firstly, the significance and the design of the project are discussed, including the design theory of the power supply and distribution system、 Preliminary design according to the load of residential buildings calculation criterion for load calculation, using three kinds of calculation methods of all kinds of used electricity load calculation and statistics, and selection of shunt capacitor of low voltage reactive power pensation...
