摘　　要：微网技术的发展,将对配电网接线的可靠性产生一定的影响。结合城市配电网典型接线模式的特点,分析了微网接入对配电网接线模式可靠性的影响。在此基础上,建立评估模型,通过改变微网的接入容量和接入位置,分析计算了不同中压配网典型接线模式的可靠性指标变化趋势,以及相同条件下不同接线模式之间的对比。通过对计算结果的分析,推荐了适合微网接入的接线模式及适合的接入容量,同时对不同接线模式的微网接入位置提出了建议。The development of microgrid technology will have an influence on the reliability of connection modes in distribution network. Combined with the features of typical connection modes in urban distribution network, the in- fluence of microgrid on reliability of connection modes in distribution network is analyzed. Based on this, an evalua- tion model is established, and the index of ASAI and its change trends are quantitatively calculated by changing the capacity and position of the microgrid. Different connection modes in the same condition are also compared. Based on the analysis of calculative results,the possible connection mode considering mierogrid is recommended, and the suitable capacity and position of microgrid is also suggested.
