摘要
10kV架空线路分段数量影响到供电可靠性,在一定范围内增加分段数量可提高供电可靠性,但分段数超过一定数量,供电可靠性不仅不增加,反而可能下降,浪费了投资。开展10kV架空线路分段的优化研究,有利于通过优化分段提高可靠性。从变电站单条出线的总费用对10kV架空线路分段的优化进行了分析,可为我国农村地区10kV架空线路分段数量的选择提供参考。
The 10 kV overhead line section number affects the reliability of power supply. Increaasing the number of line sections to a certain range can improve the reliability of power supply, but if the number of sections exceeds a certain limit, the reliability of power supply can not be improved, but may decline, resulting in investment waste. Therefore, to carry out the optimization study on 10 kV overhead line sectionalizing is conducive to improving the reliability. This paper analyzed the optimization considering the total cost of the substation single outlet, providing reference for choosing 10 kV overhead line section number in Chinats rural areas.
