Future City develops a new generation of smart substations

Recently, State Grid Beijing Electric Power Co., Ltd., together with related units, carried out inspections of the foundation pit of the main substation of the substation at the construction site of a new generation of smart substation in the 220 kV Future Technology City, Changping District.

As a new-generation smart substation demonstration project of the State Grid Corporation of China, the City 220 kV substation is the only 220 kV indoor substation in the future. After the project is completed and put into operation, it will meet the need for rapid growth in urban areas in the future.

The State Grid Beijing Institute of Economics and Technology combines the goals and tasks of building a large-scale construction, large-scale operation, and large-scale maintenance system. Based on the experience of designing, building, and operating existing intelligent substation demonstration projects, the State Council further combs and integrates the functional requirements of smart substations. Developed a new generation of smart substation program design work.

Considering the actual conditions of the project, and taking full consideration of the factors such as the saving of construction area, compact equipment layout, reduction of project cost, and improvement of safety and reliability, the station finally decided to adopt the design plan of the on-ground full-house substation with the layout of three floors above ground and one underground floor. The use of miniaturized gas-insulated enclosed combination appliances. This also became the first 220 kV indoor substation with a base floor area of ​​26.4 meters by 62 meters.

State Grid Beijing Electric Power attaches great importance to the construction of a new generation of smart substation demonstration projects. At the kick-off meeting at the beginning of the year, the company established a demonstration project leadership group and a work promotion group, and reviewed the milestone plan for the project construction. According to the plan, in the next few days, the construction personnel will carry out grounding device installation and basic cushioning work.
