Recently, China's first 220 kV new smart substation , China National Grid Xiqiao Substation, which was the first in China to realize the full integration of the Internet of Things technology and high-voltage power control technology, was completed and put into operation in Wuxi, Jiangsu.

Smart substations are an important part and part of a strong smart grid. Xiqiao Substation adopts advanced, reliable, integrated, low-carbon, and environmentally-friendly smart devices, and comprehensively uses technologies such as smart sensing, network communications, real-time monitoring, and expert systems to activate conventional substation equipment and make it intelligent. , In order to realize self-awareness, discrimination and intelligent decision-making, automatic control is completed. Smart power plants can reduce regular maintenance by reducing the number of blackouts through the use of powerful technology back-office applications. At the same time, sensor-based measurement and control networks built on the Internet of Things technology have enabled transformer substations to establish integrated standards for safety monitoring, fire alarms, and fire water supply and drainage. This substation adopts smart devices to establish sensory monitoring and control networks using the Internet of Things technology, deploying 385 sensors such as flooding, smoke, temperature and humidity, and deploying 55 high-resolution cameras and 2 infrared thermal imagers and sound and light alarms. And other facilities. No manual or robot inspections are required. The remote monitoring center can keep track of the operation of the equipment and auxiliary systems in the station and diagnose and deal with the abnormal phenomena in a timely manner.

Compared with traditional substations, smart power stations have the characteristics of smaller footprint and cable material savings. The mature and later-stage cost will be much lower than that of ordinary conventional power plants, providing preconditions and intelligent support for residents' smart power usage. Very broad.
