摘　　要：大量且不同类型的分布式电源渗透到配电网形成微网后,极大地改变了配电网传统保护配置机理。考虑到微网自身结构以及对配电网保护产生的影响,在微网保护设计中引入Multi-Agent技术理念,提出了一种基于Multi-Agent的微网分区保护方案。该方案将微网划分为若干区域,通过获取区域内阻抗元件和功率变化量方向元件锁定故障区域,运用各Agent之间的分布式处理和协作能力实现微网保护。与传统段式保护相比,该保护方案在保护配合和整体性能方面更具有灵活性和可靠性。With a large amount of distributed generators with various types integrated into the the distrihution network, the microgrid is then formulated which has greatly changed the traditional protection configuration of distribution network. Considering its ownstn, cture of microgrids and the impacts of microgrid on distribution network protection, in this paper, the theory of Muhi-Agent system is introduced to tire microgrid proteclion design, in which the microgrid is divided into several snbareas, and the faulty region can be locked by ottaining the impedance element and the directional element of power variation within each subarea. Moreover, the distributed processing and cooperation of each Agent is used to implement microgrid protection. Compared with the traditional segment protection, this design is more flexihle and reliahle in the aspects of relay coordination and overall performance.
