At 9:10 on December 4, the 50th EHV 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, second only to Jiangsu power grid and second to the domestic provincial power grid.
According to the relevant person of Zhejiang electric power of State Grid, the substation is called 500 kV Xiaowei substation. As an important part of the Zhejiang provincial demonstration project of "one picture of Dajiang east electric power", it is of great significance to optimize the power grid structure of Hangzhou Dawan District, 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 difference between the 500kV Xiaowei substation and the traditional substation is that it will become an important embodiment of the development strategy of the State Grid Corporation of China to build a' strong smart grid and the 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, realizing the functions of one key sequence control, intelligent inspection of indoor and outdoor robots, real-time control of on-site operations, etc., so as to achieve the purpose of comprehensive state perception, information interconnection and sharing, friendly human-computer interaction, highly intelligent equipment diagnosis, and greatly improving the operation and inspection efficiency.
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, high-efficiency operation inspection and reducing the life-cycle cost of equipment.
In addition, for local economic development, Xiaowei 500kV power transmission and transformation project is the first real main power supply in Hangzhou Bay industrial agglomeration area. As an important hub substation of the project, the 500kV Xiaowei substation after operation will become the main power supply point in Hangzhou dajiangdong industrial agglomeration area, East Xiaoshan area and Hangzhou Xiaoshan International Airport area, easing the power load tension in East Xiaoshan and East Dajiang area.
