单相供电在农网中的适用性

Applicability of Single-Phase Power Supply in Rural Network

针对典型农村电网结构,论述了单、三相供电模式的适用性,对农网较长线路的供电案例进行分析得出结论:单相供电模式比三相供电模式优越,具有小容量、密布点、短半径等特点,能够有效地降低配电网线路损耗以及优化电压质量,适用于三相变布点比较困难的场合。

In allusion to the typical rural power network structure,the applicability of single-phase power supply mode was discussed.Analysis was made to some power supply cases of longer line in rural network.The conclusion is that single-phase power supply mode is superior to that of three-phase power supply with the characteristics of small capacity,densely covered points,minor radius and so on.This mode can decrease line losses of distribution network effectively and optimize voltage quality,suitable for the occasion on which three-phase transformers are difficult to distribute.
