wind generator research

Introduction to the new development of wind power Crown Real Estate, a British government agency, controls the leasing of offshore areas suitable for wind farms.
In the most recent round of 3rd, these grants were taken up by offshore wind farm companies.
The lease covers offshore areas from northern Scotland to the east coast and west coast of England.
These allocations are further away from the shallow water of the coastline, so the latest technology to support deep water turbines will be used to install wind turbines with much larger capacity.
This article on renewable energy focuses on new developments in wind power generation and wind power generator research.
We first outlined a typical offshore large output wind turbine and then checked the latest technology used in the design of a large-capacity wind turbine.
Wind turbine operation overview since I have covered this topic in detail in my previous article on the operation of offshore wind turbines, I will give a brief overview of the operation of wind turbines.
Basically, the turbine consists of a nose cone that holds the blades and a cabin that holds the rest of the components.
The blade drives the gearbox through a high stretch drive, and the generator is driven by the input shaft of the gearbox.
The instrument at the rear of the cabin transmits the wind condition to the controller, which adjusts the heading and blade spacing to suit the wind condition, outputs the power cable to run along the inside of the tower, from here to the bottom of the sea, it is connected to other turbine cables.
The main cable is buried in the seabed silt and sand, landing as close as possible to the onshore substation and connecting to the state grid.
New power transmission technology in the form of high voltage DC (HVDC)
Substation has been successfully used at sea.
Compared with HVAC current, the transmission efficiency of high voltage DC current is higher and the transmission power loss is less.
Some turbines are directly driven and do not require a gearbox, but as we know, the physical size of the generator may be relatively small due to the high rotation speed of the gearbox output.
Therefore, a larger generator is needed to drive the turbine directly (
Diameter up to 12 feet)
Because the blade speed passed to the generator is less than 20 RPM.
However, Siemens has developed a new type of direct drive generator running on a permanent magnet that will operate at blade speed, which will be checked in the next section.
The latest developments in offshore wind turbines Siemens has developed a 3mw wind turbine that is much lighter than conventional wind turbines.
Their new turbine adds a permanent magnet to the turbine generator, reducing the size and weight of the generator, which is combined with the elimination of the gearbox and is where the weight is reduced.
The first prototype was installed in Denmark last year (2009)

GE is currently developing a 4 MW wind turbine model that will be put into production for offshore wind farms by 2012.
Thanks to the innovative design of the blades plus the very efficient drive chain mechanism, this new turbine will be 25% more efficient than the traditional 4 MW turbine.
The blade diameter of the new turbine is 300 feet, 360 feet high.

Offshore structures used to support large-capacity wind turbines-the latest technology currently offshore wind farms are mainly restricted to 65 feet deep, due to the cost of using fixed steel platforms used in the offshore oil and gas industry.
Recently, however, various offshore wind farm installation companies have moved to deep-
120 miles off the British coast.
The depth of these locations ranges from 150 feet to 240, and the companies propose to use floating structures similar to semi-submersible rigs used at sea and modified steel sleevesType structure.

Last year, the latest offshore wind turbine development project installed two large-capacity 5mw wind turbines and operated in deep water next to the oil and gas fields of beicui.
These wind turbines are currently the world\'s largest installed wind turbines and supply power to the oil production platform of the country\'s cuisi oilfield at 33 kV.
The field is unique for many reasons: reference site: Beatrice-the largest wind turbine in operation, the latest round of Crown property offshore submarine leases for wind turbine farms has enabled many British companies to accept the offers.
Among them are the following companies, some of which have just been formed or merged: Seaenergy PLCSeaEnergy PLC (

A new offshore renewable energy company in Scotland recently announced their plan to develop a 920 MW wind farm, the name of the country\'s offshore wind farm, the wind farm will be located next to two green silk demonstration turbines in the outer molevers.
The wind farm will consist of 184 wind turbines with a capacity of 5 MW, which will be supported by steel sleeves of traditional offshore oil platforms stacked on the seabed.
Ocean energy also applied to rent an area at the Thai estuary 10 miles off the east coast of Scotland.
This will be called the Inch Cape Offshore Wind Farm, with an output of 905 MW from 181 wind turbines with a capacity of 5 MW.
Both areas will be subject to strategic environmental assessments (“SEA\")
As well as environmental surveys and environmental impact statements on local marine flora and fauna, it will take two years to complete.

New Scottish joint venture between Mitsubishi, Scotland and Southern Energy (SSE)
Led to the signing of an agreement to explore the scope of offshore wind farm technology and carbon emission reduction and storage technologies.
Mitsubishi, the giant power company, just joined offshore wind power in February and the Scottish government has invested £ 130,000,000 ($202,000,000)
In new technology enterprises.

Build an ocean energy park on the Humber River
This will need to be built with a custom
Terminal facilities were built for the construction, installation and delivery of offshore wind turbines.
The dock will be 1,630 m long and developed with large offshore wind companies looking to build, ship and install 5000 wind turbines, Norfolk Bank will be very busy by 2020!
According to the latest technology, it is also planned to build a biomass plant in Ocean Energy Park, which will provide a lot of jobs for people in the area during construction and operation.
