1. The general layout of the booster station
The general plan of the 110kV booster station of a large electric power design institute is as follows:
The general layout of the 110kV booster station of the same wind farm is as follows:
Pros and cons analysis:
The land area is more economical: 79mx72m vs 66mx62m, saving 1308 (1.)96 acres);
The orientation of the complex building is better: east-west vs north-south, and it is more reasonable to sit north and face south (leeward and sunny in winter, and cool in summer).
The front area of the plant is more open, which is convenient for operation and maintenance parking, and has a better view.
As can be seen from the comparative analysis in Figure 3:
In Figure 2, the area of the fence is about 40% lower than the industry average, and the layout is more compact, saving about 2 million yuan.
Figure 2: The total construction area of the scheme is about 20% lower than the industry average, saving about 630,000 yuan.
Some wind power groups have adopted the centralized control method, cancelled the comprehensive building, and further optimized the area of the booster station.
Second, the construction plan of the booster station complex
The architectural design scheme of the 110kV booster station complex of a large comprehensive electric power design institute is as follows:
The architectural design scheme of the complex building of the 110kV booster station of similar wind farms is as follows:
Pros and cons analysis:
The construction area is more economical: 85176㎡ vs 734.8, reduce 117, save construction investment 2570,000;
The orientation of the complex is better: east-west vs north-south;
The functional arrangement is more reasonable: the entrance is atmospheric, and the functional partition is clear.
Note: If the centralized control method is adopted, the comprehensive building can be cancelled, and the booster station occupies less land and less construction area, which further reduces the project construction cost.
3. Wind turbine foundation design scheme
The construction drawings of the wind turbine foundation of a large electric power design institute are as follows:
The design scheme of the wind turbine foundation after optimization of the same project is as follows:
The comparison of advantages and disadvantages is shown in the following table:
As can be seen from the above table, the optimized wind turbine foundation investment is more economical: the amount of concrete and steel bars is lower, the pile type is better, and the single foundation saves 460,000 yuan, totaling 12.88 million yuan.
Fourth, summary
A good design scheme can reduce the construction cost for the owner, facilitate operation and maintenance, and have a better experience. Design is also a kind of cultivation, 3 years, 5 years, 8 years, 10 years all represent different comprehension and improvement, and you need to continuously improve your design realm in design.
Design also has a threefold realm:
The first realm: draw a scoop according to the gourd and build a concept.
The second realm: questioning, understanding, and striving to resemble.
The third realm: the pursuit of god-likeness, painting tiger skin can draw bones.
Good design, deeper understanding, more thorough thinking, more thoughtful, not only understand what to do, why to do, but also know how to do well, not confined to the existing design, have their own unique thinking and creation, with the ability to control and optimize the plan, the understanding of design is deeper and clearer.
Good drawings can see the mind and soul of the designer. It is like the third realm of Zen Buddhism: look at the mountain or the mountain, see the water or the water, know what trees to plant on the mountain, what fish to raise in the water, know the selection and matching of flowers, birds, trees, fish and shrimp aquatic plants according to the soil and climatic conditions, and build the ideal kingdom of landscape gardening in your mind, just like Zheng Banqiao's bamboo, Qi Baishi's shrimp, and Zhang Daqian's landscape, you can see clearly, paint clearly, and have a living character, thought, and soul.
