摘　　要：针对变电站状态监测系统数据管理难度高、监测精度低等问题,提出了基于物联网技术的新型计算机服务器平台。结合辅助控制系统中火灾警报传感装置,通过应用程序来实时通知用户火灾情况;构建智能变电站状态监测算法模型,通过基于局部矩阵重构的检测算法分析相邻变电站状态数据分布的差异。实验结果表明,该算法监测数据精度较高,可满足智能变电站“运维高效化、监测智能化、检修规范化”的要求。To solve the problems of high difficulty in managing data and low accuracy of monitoring data in substation condition monitoring system,a new computer server platform based on Internet of things technology is proposed.Combined with the fire alarm sensing device in auxiliary control system,the user's mobile application program is used to notify the user of fire alarm in real time.In addition,this study constructs an intelligent substation condition monitoring algorithm model,and analyzes the difference of condition data distribution between adjacent substations through the detection algorithm based on local matrix reconstruction.The experiment results show that the minimum monitoring data accuracy of the algorithm is 1.1%,which meets the requirements of “efficient operation and maintenance,intelligent monitoring and standardized maintenance” of intelligent substation.
