The number of the 50th UHV substation put into operation in Zhejiang ranks second in the provincial power grid

At 9:10 on December 4, the 50th ultra-high voltage substation in Zhejiang was put into operation in Hangzhou. So far, the number and capacity of 500 kV substations in Zhejiang have reached a new record, ranking second only to Jiangsu power grid and second in the domestic provincial power grid.

According to a person related to State Grid Zhejiang Electric Power, the substation is called 500kV Xiaowei substation, which is an important part of the Zhejiang provincial demonstration project of "a map of power in the east of the Yangtze River". It is of great significance to optimize the power grid structure of Hangzhou Bay Area, promote the economic development of Hangzhou Bay Metropolitan Economic Circle, and ensure the power supply for the 2022 Hangzhou Asian Games.

"As a new station put into operation under the background of the construction of the 'ubiquitous power internet of things', the 500kV Xiaowei substation, unlike the traditional substation, will become an important embodiment of the development strategy of the State Grid Corporation of China to build a' strong smart grid and ubiquitous power internet of things'." Zhang Jianhuan, the main person in charge of the operation of the 500kV Xiaowei substation, introduced that the 500kV Xiaowei substation will take the lead in launching the main and auxiliary equipment monitoring system in Zhejiang to achieve one-key sequential control Intelligent patrol inspection of indoor and outdoor robots, real-time control of on-site operations and other functions, to achieve the goal of comprehensive state perception, information interconnection and sharing, human-computer interaction friendly, highly intelligent equipment diagnosis, and greatly improve the efficiency of operation and inspection.

For example, the newly added "one key sequence control" status return to the background, SF6 online monitoring and other functions will play an important role in switching operation, efficient operation inspection and reducing the equipment life cycle cost.

In addition, for local economic development, the Xiaowei 500 kV power transmission and transformation project is the first real main power supply in the Hangzhou Bay Industrial Cluster. After being put into operation, the 500 kV Xiaowei substation, as an important hub substation of the project, will become the main power supply point in the Hangzhou Greater Jiangdong Industrial Cluster, the eastern part of Xiaoshan, and the Hangzhou Xiaoshan International Airport area, easing the tension of power load in the eastern part of Xiaoshan and the Greater Jiangdong area.
