摘　　要：含DG智能配电网中的潮流方向随分布式发电的变化而变化,导致配电网故障自愈的效果难以保障,因此,提出基于多Agent的含DG智能配电网差动保护自愈方法。通过构建基于多Agent的MAS体系结构,将其应用于含DG智能配电网差动保护和自愈的控制,在MAS体系结构的数据处理层完成差动保护,并在MAS体系结构的协调控制层实现故障自愈。结果表明,该设计方法不仅可以恢复配电网故障区域的电力,而且在操作次数、线损及功率因数方面可达到较理想的效果。Due to the variation of power flow direction with distributed generation in intelligent distribution networks containing DG,the self-healing effect of distribution network faults is difficult to guarantee.Therefore,a multi-Agent based self-healing method for differential protection in intelligent distribution networks with DG is proposed.By constructing a multi-Agent based MAS architecture and applying it to differential protection and self-healing control in intelligent distribution networks with DG,differential protection is completed in the data processing layer of the MAS architecture,and fault self-healing is achieved in the coordinated control layer of the MAS architecture.The results show that this design method can not only restore the power in the fault area of the distribution network,but also achieve ideal results in terms of operation frequency,line loss,and power factor.
