配电系统中常用的交流供电方式有：
①三相三线制。分为三角形接线（0.4kv电动机和照明）和星形接线（用于低压三相0.23kv工业照明配电以及0.23kv三相电动机）。
②三相四线制。用于0.4kv/0.23kv低压动力与照明混合配电 。
③三相二线一地制。多用于农村配电（因为安全问题早已淘汰）。
④单相单线制27.5kv。常用于电气铁路牵引供电。
⑤单相二线制0.23kv(由三相四线制获得)。主要供应居民用电。
配电系统由配电变电所（通常是将电网的输电电压降为配电电压）、高压配电线路（即1千伏以上电压）、配电变压器、低压配电线路（1千伏以下电压）以及相应的控制保护设备组成。配电电压通常有35～60千伏和3～10千伏等。
