The Design Of Communication For Microgrid Monitoring System Based On ZigBee

The development of social economy has enlarged the demand for energy consumption in the human society and lavishing fossil fuel has increased the negative impact on environment,In the sake of seeking a green and clean alternative,The distributed wind and solar hybrid microgrid system gains its popularity.Meanwhile,establishing the remote monitor and control system for rural areas and power grid construction inaccessible zones attracts more and more attention.It is necessary to upload real-time data of the power running status to provide a stable electric output.By optimizing the uploaded data,the barrier-free running time of the system can be improved.This essay analyses the design principle of the microgrid communication system,it proposed wireless sensor technique based on Zigbee on the foundation of analysis characteristics in microgrid,applying topology with tree structure and offering software and hardware design scheme.Information from the sensor would be upload by Zigbee wireless upload technique to monitoring centre,which would handle those information while real-time control those power generation equipment so that microgrid can work stably and securely.The hardware of terminal, router,coordinator adopts the wireless ad-hoc network module and CC2530 chip which is inexpensive,low-power consumption and low-bitrate.With the charateristics of tree structure tropology,automatic addressing distribution mechanism,a network router arithmetic was degined,the route was based on the ralationship of parent node and descendant node.The essay designed hardware and software of terminal node, router node and coordinator node,makes experiment of network completion and construction,and test the feasibility of this network.
