摘要: 为实现分布式发电微电网的灵活组网,将ZigBee应用到微电网监控网络中进行信息传输,提出一种将通信地址采用动态分配短地址附加虚拟短地址的方法,以进行微电网各单元地址唯一性识别。通过网络节点优先接入能量峰值高的信道方式,提高通信链路的可靠性。实验结果表明,动态分配短地址与虚拟短地址相结合能够正确识别现场设备的地址,与ZigBee设备出厂时分配的64位唯一地址相比,应用短地址能更有效减小通信中数据包的长度,网络测试证实其通信距离和数据传输稳定性满足微电网监控网络的需求。

Abstract: In order to realize the flexible construction of microgrid with distributed generation,ZigBee is used to transmit information for the monitoring network of microgrid.Communication address that is composed of dynamic short address and virtual short address is proposed to identify unique address of each unit of microgrid.The ZigBee network nodes preferentially connect with the channel of high peak energy to improve the reliability of communication link.Experimental results show that the combination of dynamic short address with virtual short address can correctly identify the address of the field device.Compared with the 64 bit unique address assigned by ZigBee manufacturer,the application of short address can reduce more effectively the data packet length during communication.The tests of network verify that both communication distance and stability of data transmission meet the monitoring network requirement of microgrid.

Key words: microgrid, distributed generation, monitoring network, ZigBee communication, virtual address
