传统智能变电站监测系统监测范围小，抗干扰性能差，为此提出基于物联网技术与分层分布式结构的智能变电站在线监测系统设计。设置无线物联传感器模块，将监测系统的通信结构设置为分层分布式结构，按照断路器间隔分别进行测量、控制和继电保护功能；在物联网环境下通过实时数据采集、并行数据传输实现智能变电站的在线监测功能，计算故障位置坐标，实现智能变电站在线监测。实验结果表明，设计监测系统的平均监测范围相较传统系统扩大了60.5%,且抗干扰性能更佳。

The traditional smart substation monitoring system has a small monitoring range and poor anti-interference performance. A design of online monitoring system for smart substations based on the Internet of Things(IoT) technology and hierarchical distributed structure is proposed. It is equipped with a wireless IoT sensor module, and the communication structure of the monitoring system is modified into a hierarchical distributed structure, and the measurement, control and relay protection functions are respectively controlled according to the breaker interval; in the IoT environment through real-time data collection and parallel data, the transmission realizes the online monitoring function of the smart substation, calculates the coordinate of the fault location, and realizes the online monitoring of the smart substation. The experimental results show that the average monitoring range of the designed monitoring system is 60.5% larger than that of the traditional system, and the anti-interference performance is better.
