摘要

交流微电网系统保护按其功能可分为并网保护和微电网内部保护。文中以交流微电网的结构和特点为基础，重点分析不同规模微电网并网保护，参照微电网类型将其分为系统并网保护、区域并网保护及单元并网保护。通过对不同级别微电网负荷、运行方式进行分析，结合各级微电网的功能，提出3种类型并网保护的配置策略。考虑到大型微电网结构复杂，不同级别微电网之间可能存在包含关系，分析了发生区内、区外故障时3种类型并网保护之间动作时间的配合。最后在PSCAD/EMTDC中建立IEEE P1547.4典型微电网拓扑，仿真验证了并网保护配置方案的有效性与可行性。

Abstract

Microgrid protection can be divided into interconnection protection（IP）and inner microgrid protection（IMP）according to its function.The structure and characteristics of IP are highlighted.The IP is classified into three types:system IP，distributed IP and unit IP according to the classification of microgrid.Through an analysis of microgrid load，operation modes and functions，the configuration strategies of IP are proposed.By considering the complicated structure of large-scale microgrid and co-existence of three types of microgrid，coordinating strategies are also put forward.The typical topology of IEEE P1547.4is established in PSCAD/EMTDC in order to verify the feasibility and effectiveness of the protection scheme.
