The completion of the Fujian-Guangdong interconnection project will ease the seasonal power supply shortage in Guangdong

　　On July 29, at the base of a tower at the junction of Fujian and Guangdong provinces, with the completion of the tower erection on the last wire, the main project of the Fujian-Guangdong interconnection line was completed, marking the completion of the Fujian-Guangdong interconnection project
.

　　The Fujian-Guangdong Interconnection Project is a key power transmission and transformation project clearly proposed by the state to make up for shortcomings in infrastructure.
It is also the first provincial-level interconnection project between State Grid Corporation and China Southern Power Grid Corporation
.
The total length of the project line is 303 kilometers, with a transmission capacity of 2 million kilowatts.
A new DC back-to-back converter station is built in Fujian Province.
Through two AC 500 kV lines, it is connected to Guangdong Jiaying and Fujian Donglin 500 kV substations respectively
.

　　"After the completion of the Fujian-Guangdong interconnection project, it will promote the mutual aid between the surplus and shortage of electricity in the two provinces, and the surplus electricity in Fujian can be sent to Guangdong to ease the seasonal power supply shortage in Guangdong
.
At the same time, it will help give full play to the advantages of Fujian's clean energy resources reserves and further optimize Guangdong, Hong Kong and Macao The energy structure of the Greater Bay Area and the economic zone on the west coast of the Taiwan Strait can improve the energy security capability
.
" Xie Rongchang, deputy general manager of the Infrastructure Department of China Southern Power Grid Guangdong Power Grid Company, introduced
.

　　According to estimates, during the "14th Five-Year Plan" period, through the interconnection between Fujian and Guangdong, the seasonal power transmission between the two places can reach 500,000 kilowatts to 1.
6 million kilowatts, which is equivalent to reducing the construction of a large thermal power plant
.
In addition, the Fujian-Guangdong interconnection project can also increase the anti-risk capabilities of the power grids of the two provinces, which will effectively improve the emergency support capabilities of Fujian and Guangdong in the event of natural disasters, and speed up the recovery after the accident
.

　　China Southern Power Grid Co.
, Ltd.
actively serves the overall situation of "six stability" and "six guarantees", and makes every effort to "consolidate, supplement and strengthen the chain" to promote high-quality economic and social development
.
Since the beginning of this year, the cumulative investment in Guangdong has exceeded 27.
6 billion yuan
.
Among them, the Fujian-Guangdong Interconnection Project has a total investment of 3.
2 billion yuan, which involves a long industrial chain and various types of equipment.
It will drive the economic development of more than 10 upstream and downstream industrial chains, such as raw materials, electrical equipment, and energy-using equipment, and is expected to drive energy equipment manufacturing.
The value of the downstream industry chain is about 1.
1 billion yuan
.

　　In addition, the Fujian-Guangdong interconnection project fully absorbs and draws on the latest achievements in cutting-edge technology fields such as UHVDC transmission in China, which can well adapt to the technical requirements of the interconnection of the two networks
.
Technologies such as reactive power compensation devices, remote sensing images, all-digital photogrammetry systems, and three-dimensional information management platforms for power grids are used to optimize line paths and promote project progress
.
After the project is put into operation, it will achieve a 100% localization rate of important technologies, and promote a new round of technological breakthroughs in China's power industry
.

　　"The Fujian-Guangdong Interconnection Project is scheduled to start the AC system on August 13, which will become a symbol of the formation of the physical channel of the two provinces
.
" Xie Rongchang said that in the next step, the Fujian-Guangdong Interconnection Project will comprehensively speed up the installation and commissioning of converter substation equipment.
It is planned to be completed and put into operation in October this year
