The online monitoring system of smart substation realizes the platform of information sharing, the network of system framework, the visualization of equipment status, the panoramic monitoring target, the digitization of the whole station information, the standardization of communication protocols, the component of monitoring function, the integration of information display, the real-time collection of the status data of equipment in the station, the comprehensive diagnosis and analysis and the whole life evaluation. On the one hand, the substation monitoring system is an independent network of internal interconnected transformer equipment; on the other hand, it is also a node of the remote master station, which sends the monitoring and diagnosis system of the substation's internal equipment and its own status information to the master station.
Environmental monitoring system is to ensure the safe, stable and efficient operation of the organization, ensure the good running state of network equipment and equipment service life and safety, to achieve the maximum investment benefit of users, it is necessary to the network operating environment of power supply, temperature, humidity, water leakage, air dust content and many other environmental variables for real-time monitoring. In order to improve the safety operation guarantee ability of substation, it is necessary to automatically detect and identify the video images of moving targets in substation equipment areas, especially in high-voltage dangerous areas, and timely warn that events may occur or are in progress, so as to prevent the occurrence of events or produce more serious consequences.

The smart power Internet of Things aims to improve the safety of power operation and reduce the cost of operation and maintenance. It adopts the Internet of Things and cloud computing technology to upgrade the power equipment such as the distribution room, box-type substation and distribution box (cabinet), and build the Internet of Things for the user-side power system. At the same time, with the help of modern information technology such as big data and artificial intelligence, intelligent operation and maintenance of power system can be realized through intelligent terminals, monitoring screens and mobile apps. According to different customer needs, targeted data services and platform systems can be provided for owners, manufacturers and maintenance providers! Effectively ensure the safe, controllable and efficient operation of power equipment! It is a modern tool of power system operation and maintenance management.
