基于物联网的变电站在线监测系统

On-line monitoring system for substation using internet of things

针对智能电网的发展需求,基于物联网技术设计了变电站运行数据在线监测系统,提出了在新型ZigBee射频芯片CC2530前端添加射频功放芯片CC2591来延长协调器和路由器通信半径的物联网节点设计方案,同时设计了监测系统中的数据发送和组网流程,并针对某煤矿变电站做了现场测试工作。测试结果及传输实验表明,系统工作稳定性高,数据传输实时性好,具有较高的推广应用价值。

This paper has expounded the basic principle and process of using the internet of things for monitoring substation operation data. The internet of things is a complex and very huge system, which can connect one thing to another. This paper only introduces using ZigBee in the bottom network layer as a transmission agreement. In the hardware design, a new ZigBee chip CC2530 is used for communication. In order to extend the communication ra dius of the coordinator and router, a CC2591 is added to the frondend of CC2530 as power amplifier. In the soft ware design, the process of datasending and networking is designed. Test work has been finished in a substation of a cement plant. The monitoring data of substation can be clearly shown by the testresults. This paper shows an ac tive power picture in the end, which vividly describes the change of load. The testing results and transmitted exper iments show that the monitoring system is of high stability and good electromagnetic compatibility, which has very high application and popularization value.
