摘　　要：针对企业自备电厂的特点,通过工程实例说明要有合理的电气主接线,就应该正确选择自备电厂电量交换点。并提出应该从负荷分布情况、机组容量和数量、短路水平和配电电压等四个方面来确定电量交换点的电压等级。According to the feature of the self-supply power plants, we must select the point about electric energy exchange correctly in order to design appropriate wiring diagramo We should be sure of the point about electric energy exchange by load distribution, unit capacity and number, short-circuit level and distribution vohage.

关 键 词：自备电厂 电量交换点 电压等级
