主要内容：
对中小型工厂的供配电系统进行设计，采用10kV供电电源，在金工车间东侧1020m处有一座10kV配电所，先用1km的架空线路，后改为电缆线路至本厂变电所，将6—10kV的高压降为一般低压用电设备所需的电压，然后由低压配电线路将电能分送给各用电设备。其它各项设计，均应根据本厂用电负荷的实际情况，并适当考虑到工厂生产的发展，按照安全可靠、技术先进、经济合理的要求进行设计。

2.1.2供电协议
（1）从电力系统66/10KV变电站用10kV架空线路向工厂馈电。该变电站南侧1km。
（2）系统变电站馈电线路定时限过流保护装置的整定时间t=2s，工厂总配电所保护整定时间不得大于1.5s。
（3）在工厂总配电所10kV进线侧计量。 （4）工厂最大负荷是功率因数不得低于0.9。 （5）供电系统技术数据：
电业部门变电所10千伏母线，为无限大电源系统，其短路容量为200兆伏安。供电系统如图2.2所示。

2.2负荷计算的意义及相关参数的计算
2.2.1 负荷计算的意义
负荷计算是设计的基础，它决定设备容量的选用，管网系统的规模以及工程总造价等，这是技术人员熟知的事实。但是近几年来用估算的方法替代了负荷计算，给制定方案、工程审核造成一定的困难。本文通过实例，介绍关于负荷计算
