摘　　要：大量分布式电源(DG)接入配电系统后,供电模式的灵活性和运行方式的复杂性将对配电系统可靠性评估提出新的要求。在馈线分区的基础上,引入基于成功概率的可靠性分析方法——GO法,建立了计及DG影响的配电系统可靠性评估模型,该模型量化分析了各馈线分区设备故障对含DG区域节点的可靠性影响。并通过算例验证了该模型的有效性和实用性,结果表明GO法适用于较大规模的含DG配电系统的可靠性评估,考虑设备检修状态能更真实地反映配电系统可靠性的实际状况。With significant penetration of distributed generations （DGs）, flexibility of power supplying mode and complexity of operation mode bring on new requirements to reliability assessment of distribution system. A reliability analysis method called the GO methodology based on success probability is introduced to the power system filled with feeder partition, and a distribution system reliability evaluation model is built considering the DG influence, which quantifies the reliability effects on zone nodes by the equipment failure in other feeder partitions. The example simulation demonstrates the efficiency and practicability, and the results show that GO methodology is suitable for reliability evaluation of large-scale distribution systems with DG, furthermore the actual state of distribution system reliability can be more truly reflected by considering the status of equipment maintenance.
