Abstract
A kind of 35KV distributing double-fed fan motor unit electrical system integrated system, the system comprises converter system, 35KV box type transformer, 35KV switchgear and the tower external platform hangings above and below access point；The converter system and 35KV switchgear are mounted on tower internal platform；The 35KV box type transformer is mounted on tower external platform hanging.The utility model realizes that distributing Wind turbines access 35KV power grid under the premise of not increasing distributing Wind turbines land used.It is i.e. by increasing tower external platform hanging that 35KV box type transformer is external, arrangement space deficiency can be solved in tower and reduce heat dissipation in tower, 35KV power grid is finally incorporated to by 35KV switchgear output electric energy, electrical system integrated approach is simple, reliable, perfect in shape and function.
Description
Technical field
The utility model relates to one kind to have mounting structure novelty, the 35KV distributing double-fed fan motor unit electricity of perfect in shape and function
Gas system integration system.
Background technique
With the continuous development of wind power technology, centralized wind-powered electricity generation is influenced by power grid digestion capability and equal factors, " abandonment "
" rationing the power supply " phenomenon is got worse, and compared with centralized wind-powered electricity generation, distributing wind-powered electricity generation has advantage: exploitation scale does not account for approval index；
Project land used is relatively free, and occupied area is small, the construction period is short；Do not create booster stations；Close to load center, it is easier to grid-connected to disappear
It receives；It is grid-connected secure；Main part of development is unlimited.From country and local policy: in April, 2018, the publication of National Energy Board official website
" distributing Wind Power Project development & construction provisional administrative method " releases the signal of clearly strong encouragement distributing Wind Power Development.
The year two thousand twenty bottom wind-powered electricity generation Wind Power Project will all realize cheap internet access, and wind-powered electricity generation mark post price necessarily will be lowered gradually during this period.Institute
With from the best period for the year two thousand twenty being now distributing exploitation.In June, 2018, Bureau of Energy, Shaanxi Province is according to National Energy Board
" distributing Wind Power Project development & construction provisional administrative method ", has issued " Shaanxi Province " 13 " distributing Wind Power Development scheme
(draft) ".Shaanxi Province's distributing Wind Power Development solution Items have been issued simultaneously, and submitting voltage class is 35KV.
From the point of view of the overall situation and main trend of energy revolution, distributing wind-powered electricity generation meets China's clean energy, low-carbon, decentralized
The route of development, the appearance based on advantage and industrial policy that distributing wind-powered electricity generation has, distributing Wind Power Generation layout is positive to be accelerated
It promotes.
Existing a kind of Wind turbines electrical system integrated approach of solution, by box type transformer installation and Wind turbines
Separation, needs to build booster stations, land occupation resource does not meet the technical requirements of distributing wind-powered electricity generation.It can be seen that designing one kind
35KV distributing double-fed fan motor unit electrical system Integrated Solution, overcomes box type transformer land occupation resource, is that this is practical new
The research emphasis of type.
Summary of the invention
For the deficiency of existing wind power technology.It is separated for box type transformer installation with Wind turbines, needs to build booster stations,
Land occupation resource.It is a kind of novel with mounting structure that the utility model provides, the 35KV distributing double-fed fan motor of perfect in shape and function
Unit electrical system integrated system.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of 35KV distributing double-fed fan motor unit electrical system integrated system, the system comprises the changes above and below access point
Flow device system, 35KV box type transformer, 35KV switchgear and tower external platform hanging；The converter system and 35KV switchgear peace
Mounted in tower internal platform；The 35KV box type transformer is mounted on tower external platform hanging.
Further, the converter system, 35KV box type transformer and 35KV switchgear are fully integrated into 35KV distributing
Double-fed fan motor unit.
Further, the 0.69KV electric energy that the exported Wind turbines of the converter system issue passes through cable connection extremely
35KV box type transformer；The 35KV switchgear carries out on-off and protection to the electric energy that distributing Wind turbines issue.
The beneficial effects of the utility model are mainly manifested in: (1) it is from traditional centralized Wind turbines scheme different, 35KV points
It dissipates formula double-fed fan motor unit electrical system integrated approach and box type transformer is integrated in tower external platform hanging, economize the land resource；
(2) box type transformer of 35KV distributing double-fed fan motor unit is external, arrangement space and can subtract in effectively save tower
Heat dissipation in few tower；
(3) 35KV distributing double-fed fan motor unit can realize the operation and maintenance to box type transformer, maintainability outside tower
More preferably.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of 35KV distributing double-fed fan motor unit electrical system integrated system；
