Beijing opens its first smart substation

The reporter learned from Beijing Electric Power Company that the intelligent transformation of the first 220-kilovolt transformer substation in Beijing is underway at the Zuo’anmen substation. Smart substations will use new technologies. When an equipment accident occurs, the repair time can be reduced from 10 hours to 1 At that time, the user's power outage time will also be shortened accordingly.

On August 19th, the intelligent transformation project of the Zuo’anmen substation was officially launched. This is also the first smart substation in Beijing. This smart substation will use advanced, reliable, integrated, low-carbon, and environmentally-friendly smart devices to digitize and communicate information across the entire station. Platform networking and standardization of information sharing are basic requirements, and basic functions such as information collection, measurement, control, protection, metering, and monitoring are automatically completed, and can support real-time automatic control of the power grid, intelligent adjustment, on-line analysis and decision-making, and coordination and interaction as required. Functions to realize substations that interact with neighboring substations and power grids.

Today, the intelligent transformation project of the Zuo’anmen substation has started for a full month and the renovation is proceeding in full swing. In the renovation project, many substations have applied many innovative technologies. Among them, the relay terminal reinforcement bracket kit developed by the transformation company Xiao Yongli Innovation Studio and its heavy-duty connector are being applied.

The use of the new device can greatly shorten the time for replacing the protection device in the event of an equipment accident. The replacement time of a set of 10 kV relay protection devices can be shortened from the original 10 hours to 1 hour, and at the same time, it can be shortened. The user's power outage time. This scientific and technological innovation was used for the construction of this smart substation and improved the reliability of power supply for the entire substation and the entire Beijing power grid. Relevant person in charge said that in the future, this scientific and technological innovation will be widely applied in substation renovation projects and infrastructure substations.
