385 sensors build 200 million yuan to build smart substations

Now, if a stranger dares to break into the Xishan substation in Huishan District without permission, then it is estimated that in less than five minutes, he will be directly “taken down” by the staff. Because from the moment he touched the security door of the substation, he took in the eyes of the staff. First, the vibration sensor on the security door will transmit the vibration information to the video system. Then, the information will be transmitted to the sound and light alarm system through the video system for alarm. What made this happen was several sensors that were only one dollar in size. These small sensors collected various information and, through the linkage between them, quickly and accurately issued instructions to the staff of the general monitoring room.

This is the scene that the reporter saw on December 30th at the 220 kV Xiqiao Smart Substation in Huishan District, Wuxi City. As the first 220 kV smart substation of the State Grid, on December 30th, the Xixi Smart Substation in Wuxi City, a combination of the Internet of Things technology and high-voltage power control technology, was officially completed and put into operation. The 385 sensors spread throughout the entire substation become the core of this smart substation core. These monocoque-sized white wafers transmit minute changes in the surrounding environment to the control center's on-line detection system at the first time by sensing the temperature, humidity, water level, and smoke in the surrounding environment.

“For example, the temperature and humidity sensors can automatically adjust the size of the vents and the temperature of the air conditioners by sensing the temperature and humidity in the surrounding environment.” On December 30, the city power supply company transformed the power supply. Mr. Lu, the person in charge of the operation center, told reporters that the project “activates” traditional equipment in substations through the integrated use of smart sensing, network communication, and real-time detection technologies, making it intelligent and self-aware. Discriminate and intelligent decision-making, automatic control.

It is understood that in addition to these magic sensors, as the first 220 kV smart substation of the State Grid, Xiqiao Intelligent Substation also implements the concepts of resource conservation, environmental friendliness and industrialization during the construction process. Large-scale use of small-sized, small-area combined electrical equipment, compared with the standard design of the same scale, the building area has been reduced by 10%; through the use of multiple network communications, information and other technologies, the use of control cables and communication cables is greatly saved. The project uses nearly 15 tons of less-used copper materials. By arranging LED energy-saving lamps, it saves 31.6% of electricity compared to substations of the same size. With the intelligent ventilation system, the total energy saving of the station is about 25 kwh. It is also understood that the Xiqiao Smart Substation Project started in March 2010 has a total investment of RMB 207.22 million.
