Zhejiang's first 220 kV intelligent substation started construction

On August 20, Zhejiang’s first 220 kV intelligent substation—220 kV cloud will officially start construction. The substation is the second batch of smart grid construction pilot projects of the State Grid Corporation and is scheduled to be completed and put into operation in December this year.

The station takes the digital information of the whole station, the communication platform network, and the standardization of information sharing as the basic construction requirements. It adopts advanced, reliable, integrated, low-carbon, and environmentally-friendly intelligent equipment, which not only can automatically complete information collection, measurement, control, and protection. Basic functions such as measurement and monitoring, and more importantly, it also supports advanced functions such as real-time automatic control of the power grid, intelligent adjustment, on-line analysis and decision-making, and cooperative interaction.

"The 220 kV cloud-changing smart device will realize the intelligentization of circuit breakers, disconnecting switches and other devices through the intelligent terminal, and realize the digitization of the current and voltage of the electronic transformer through the merging unit, thereby realizing the visualization of the device status and the intelligent alarm. And comprehensive analysis and decision-making and other advanced applications.” Said Zhejiang Wenhuafa, who is responsible for the construction of Transmission and Distribution Engineering Corporation in Zhejiang Province.

It is reported that the completion and commissioning of the substation will further promote the development of the smart grid in Zhejiang, improve the grid structure of the northern part of the city grid in Hangzhou, and promote the upgrading of power grid technology, improve the safety and stability of power equipment operation, and meet the regional new load. Electricity demand plays a very positive role.
