摘　　要：针对中压配网设备管理松散、管理效率低的问题,通过融合物联网技术对管理模式进行优化改进,设计了两芯环形通信物联网中压配网设备管理系统。采用网格化管理模式组成严谨的设备管理方式,利用多种终端提高指令的强控性。设计两芯环形通信线路,避免了传输信号的中断,从而保证管理指令的顺利传达。在技术上,为了提高数据信息处理能力,构建了改进信赖域算法。该算法通过运行状态中的有功和无功功率,有效保证了系统节点传输过程的安全性。通过Proteus软件,仿真配网设备运行过程。试验结果表明,网格化中压配网设备管理系统负荷最大为473.58 kVA,管理指令传输速度为8.4 MB/s,设备管理效率为96.5%。通过仿真对比三种不同管理模式指令传输速度和设备管理效率曲线,验证了所提系统的优越性。Aiming at the problems of loose equipment management and low management efficiency of medium voltage distribution network,the two-core ring communication Internet of Things(IoT)medium voltage distribution network equipment management system is designed by integrating IoT technology to optimize and improve the management mode.The grid-based management mode is used to form a rigorous equipment management mode,and multiple terminals are utilized to improve the strong control of instructions.The design of two-core ring communication line avoids the interruption of transmission signal,thus ensuring the smooth transmission of management instructions.Technically,to improve the data information processing ability,the improved trust domain algorithm is constructed.The algorithm effectively ensures the safety of the transmission process of the system nodes through the active and reactive power in the operation state.The operation process of distribution network equipment is simulated by Proteus software.Test results show that the maximum load of the grid-based medium voltage distribution network equipment management system is 473.58 kVA,the transmission speed of management commands is 8.4 MB/s,and the efficiency of equipment management is 96.5%.The superiority of the proposed system is verified by comparing the command transfer speed and equipment management efficiency curves of three different management modes through simulation.
