摘　　要：提出了一种利用已有的10 kV开关站资源,通过二级环网线路组成"2-1"、"3-1"、"4-1"的接线模式,从而可在满足"N-1"的条件下对配电网进行改造。实际改造工程的运行经验表明,应用这几种接线模式后供电可靠性得到了提高。同时由于充分利用了原有开关站资源,节约了改造费用。因此,该研究成果可为类似供电区域的配电网环网的升级改造提供参考。Based on the existing 10 kV switching substations, this paper puts forward connection modes of ＂2-1＂, ＂3-1＂ and ＂4-1＂ formed by the secondary ring network line, which are able to renovate the power distribution network under the condition of ＂N-1＂. The operation experience of the real renovation project shows that the power supply reliability has been enhanced after the application of these several connection modes. Meanwhile, due to fully tapping the original switching substations, renovation expenditure was cut down. Therefore, the result provides a reference model for the upgrading and renovation of power distribution ring network in similar power supply areas.
