摘要
主要对不同单相配电方式的电量损耗进行了定量分析,并在Dig Silent中对系统电压分布及供电可靠性进行了仿真。通过对比配电台区高压侧、低压侧的不同接线方式,定量计算了不同接线方式下的电量损耗。在高、低压侧线路长度一定的条件下,单相配电变压器输送不同的有功电量,高压侧采用接于线电压方式,低压侧采用单相三线制。在配电台区输送相同电量且高压侧线路长度相同的条件下,低压侧线路长度变化时,高压侧采用接于线电压方式,低压侧采用单相三线制。通过本文计算分析,从减小配电台区电量损失的角度出发,在负荷分散的农村地区推广单相配电,高压侧宜采用接于线电压的方式,低压侧宜采用单相三线制。该研究对于单相配电方式的应用有一定的指导意义。
This paper study on the electric energy loss of different single-phase distribution system. By comparing different connection modes of single-phase distribution system, we get the result of electric energy loss of different sin- gle-phase distribution system. In the same condition of electric transmission line, when transmitting different power, the high-voltage side shuld connect to line voltage and the low-voltage side should use single-phase three wire sys- tem. In the same condition of transmitting power and transmission line of high-voltage, when the low-voltage transmis- sion line is different, the high-voltage side shuld connect to line voltage and the low-voltage side should use single- phase three wire system. The study has some significance for the urban medium voltage distribution network planning.
