针对交流微网保护的特殊性，提出了采用电流量的综合幅值和相位变化量构建相互独立的双重差动判据的集中式保护方案，且通过“广域”保护的区域划分方法，扩大保护范围，增强了保护系统的后备能力。同时，针对现有低压配网结构，提出基于ZigBee无线组网技术的保护通信架构。通过Matlab仿真，验证了该保护方案的有效性。

In view of the special nature of the protection in micro-grid,this article proposes a centralized protection scheme, which uses electric current comprehensive amplitude and phase variation of the dual differential to build a mutually independent criterion and expands the scope of protection and improves performance of the protection system through the region division method for“WAN”protection. At the same time,in view of existing low voltage distribution network structure,the paper puts forwards the communications architecture for protection based on ZigBee wireless networking technology. The protection scheme has proved effective through Matlab simulation.
