Yongzhou City will build the second 500kV line project from Yongzhou Zongyuan to Zixia to improve the reliability and voltage level of Yongzhou power grid, and to strengthen the power supply capacity of the "North Power South Transmission" channel of the Shonan 500kV power grid. #永州头条 #
Mainly # Yongzhou # north of the Zongyuan substation under the grid power has been heavy, Yongzhou power grid for "North Power South Transmission", Shonan southern 500kV power grid is weak only a single ring network, grid operation constraints, poor reliability, in addition to guohua Yongzhou power plant construction into the final stage, unit 1 is scheduled to be put into operation in September 2021, unit 2 at the end of the year put into operation to generate electricity.
The static investment of the project is 450.45 million yuan, of which the environmental protection investment is 7.2693 million yuan, and it is planned to be put into operation this year. The length of the line is about 90km, the line voltage rating is 500 kV, and it is planned to build 262 base towers, which are divided into 200 base linear towers and 62 base tension towers. The project construction site passes through Yongzhou #Cold Water Beach#, #Lingling# District, Shuangpai County, and Ningyuan County.
The project was originally two plans for the east and the west, and the initial use of the east plan, because the total investment is less than 33.99 million yuan, mainly because the east plan is 11.3km shorter than the total length of the west plan, and the traffic conditions, construction and operation are better than the west plan.
The line project is divided into three parts: 1, Yongzhou Zongyuan ~ Zixia second single loop erection of 500kV line; 2, Zongyuan 500kV substation expansion 500kV line interval 1, a new set of DC ice melting devices; 3, Zixia 500kV substation expansion 500kV line spacing 1.
