recently
It was built by China Construction First Bureau Construction and Development Company
Ningxia Zhongning ± 800 kV converter station project
Civil Engineering Package A Project
Smoothly break out of plus or minus zero
It officially entered the construction stage of the main structure above ground
The project is the implementation of the National Energy Security Strategy
"Strengthen large-scale wind power and photovoltaic bases
and the construction of delivery channels".
After completion, it will enhance the capacity of "west-to-east power transmission".
Draw a new chapter of "double carbon".
Help optimize the allocation of new energy on a large scale.
▲Project renderings
The project is located in Ningxia Hui Autonomous Region
The building area is about 17,000 square meters
The construction content includes high-end valve hall and low-end valve hall
Main control building, integrated water pump room, etc
After the completion of the project, it will be fundamentally solved
The problem of grid-connected consumption of new energy in the central and southern regions of Ningxia
Optimize the allocation of power resources on a larger scale on the mainland
It is of great significance to help high-quality economic development.
West-to-East Power Transmission: Write a new chapter in the large-scale development of the western region
▲ Real picture of the project
It was emphasized at the forum on promoting the large-scale development of the western region in the new era
It is necessary to speed up the construction of a new energy system
Expand and strengthen a number of important national energy bases
Strengthen the interconnection of pipe networks
Enhance the ability of "west-to-east power transmission".
The project is the first of its kind in mainland China
A power transmission channel based on clean energy transmission
Promote Ningxia's advantages in clean energy resources
translates into economic advantages
Better play Ningxia's internal and external mutual access and multi-energy complementarity
The pivotal role of the West-East Power Transmission Grid for regional mutual aid
Effectively guarantee the power supply in Hunan.
Mutual assistance between surplus and shortage: stable transmission of high proportion of new energy
▲ Real picture of the project
The "Ningdian into Hunan Province" project is
It is included in the national "14th Five-Year Plan" electric power development plan
Key projects of inter-provincial and inter-regional transmission channels
It is also the first in the country to focus on deserts, Gobi and deserts
Large-scale wind and solar base sends UHV DC channel
As the starting point of Ningxiang DC UHV project
After the project is put into service
It can deliver 360-40 billion kilowatt hours of electricity to Hunan every year
Increase the electricity consumption of Hunan by about 1/6
Become Ningxia's practice of "double carbon" goals
An innovative project to achieve a high proportion of new energy and stable transportation
A demonstration project to help optimize the allocation of new energy on a large scale
For the mainland, the surplus and shortage of power will be mutually beneficial, and the time and space will complement each other
Multi-energy interchangeability is of great significance.
Keep improving: a new type of anchor bolt positioning device
▲Application of anchor bolt positioning mold
During construction
Due to the difficulty of reactor foundation construction
High precision and small error are required
The project team combined with the actual situation on site
The reactor base anchor bolt is used to locate the mold
Replace the traditional anchor bolt installation and fixing method
It not only effectively simplifies the traditional installation and construction process
It can also ensure the overall positioning of anchor bolts accurately
Large-scale deviation is effectively avoided.
