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 500kV substations in Zhejiang Province have reached a new record, second only to Jiangsu power grid and second to provincial power grid in China.

The 500kV Xiaowei substation is an important part of the "one map of dajiangdong power" Zhejiang provincial demonstration project, which 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 substation put into operation under the background of the construction of" ubiquitous power Internet of things ", the difference between 500kV Xiaowei substation and traditional substation is that it will become an important embodiment of the development strategy of State Grid Corporation of China to build" strong smart grid and ubiquitous power Internet of things. " Zhang Jianhuan, the main person in charge of 500 kV Xiaowei substation's commissioning, introduced that the 500 kV Xiaowei substation will take the lead in launching the main and auxiliary equipment monitoring system in Zhejiang Province, realizing the functions of one key sequence control, intelligent inspection of indoor and outdoor robots, real-time control of field operation, etc., so as to achieve comprehensive state perception, information interconnection and sharing, friendly human-computer interaction, highly intelligent equipment diagnosis, high reliability and reliability The purpose is to greatly improve the efficiency of transportation and inspection.

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

In addition, for local economic development, Xiaowei 500kV power transmission and transformation project is the first real main power source in Hangzhou Bay industrial cluster area. After being put into operation, the 500kV Xiaowei substation, as an important hub substation of the project, will become the main power source of Hangzhou dajiangdong industrial cluster area, Eastern Xiaoshan area and Hangzhou Xiaoshan International Airport area, Ease the power load tension in the east of Xiaoshan and the east of Dajiang.
