On December 28, with the successful charging of 500 kV Huiao Line A and B, Dieqiao Line A and B, Guangdong Power Grid's "14th Five-Year Plan".The 500 kV line project supporting the southwest outer ring of Zhuhai was officially put into operationIt further optimizes the internal power grid architecture of the southwest Zhuhai area of the Guangdong-Hong Kong-Macao Greater Bay Area to improve the reliability of power supply.
It is understood that the supporting project of the outer ring of southwest Zhuhai is the second phase of the key project of the target grid in GuangdongThe total investment is 113.7 billion yuan, the new 500 kV double-circuit line with the tower is about 2 1254 kilometers, passing through 4 cities of Foshan, Jiangmen, Yangjiang and Qingyuan.
Among them, the total investment of Yangjiang section is 42.7 billion yuan, 52 kilometers of new 500 kV double-loop line with the tower, involving 6 towns and a total of 123 base towers, can further optimize the power grid architecture after completionFurther help the construction of Guangdong (Yangjiang) International Wind Power City
Li Zhen, Project Manager of Project Management Center of Yangjiang Power Supply Bureau:After the completion of the project, it will give full play to the power mutual aid and accident support capacity of the outer ring power grid of the Greater Bay Area to the southwest of Zhuhai, improve the voltage support capacity of the outer ring of the Greater Bay Area, meet the development needs of the load area in southwest Zhuhai, improve the power supply capacity and reliability of the power grid in the Greater Bay Area, and meet the demand for surplus power transmission in the western part of Guangdong.
For the first time, the project adopted the construction method of 35 thousand volt cable under the groundIt can greatly reduce the power outage time of users。It took only half a year from the start of construction to the commissioning of the Yangjiang section of the line.
Li Zhen, Project Manager of Project Management Center of Yangjiang Power Supply Bureau:The first is to provide an effective channel for power transmission from west to east for large power plants such as Yangxi Thermal Power Plant and Qingzhou Offshore Wind Power, and the second is to increase the external interconnection channel of the power grid in Yangjiang area, improve the 500 kV backbone grid structure, and make the power supply in Yangjiang more stable and reliable.
