« The Future of the (the First part of article has been written in July 2006, |
In article the analysis of prospect of development of high-power windturbines is carried out. This analysis show, that existing
traditional 2 - 3 bladed wind turbines because
of lacks inherent in them do not allow to raise essentially gathering of wind energy
(each separate turbine) and, in sense of appreciable increase of efficiency, have exhausted
the opportunities.
In article for the first time the new design of a rotor of the turbine is offered. It allows to increase efficiency (so to reduce
cost of wind energy) approximately in 1,5 – 2,5 times
at preservation of the sizes of rotors. The result is achieved owing to increase up to
60 % of coefficient of use of wind power (Ñð) and more optimum use of strong winds owing
to reduction in a new design of loading on
blades. In addition to this application
of a design receives an opportunity to increase the sizes of rotors without deterioration
of their
characteristics at an allowable rise in price down to powers 100 – 200 MW
on the turbine. The general increase in efficiency in this case
makes approximately
3 – 5 times. As a matter of fact, the offered design is the next generation of wind high-power turbines.
Such increase of efficiency guarantees in the nearest future
the transition of all leading wind energy firms on the release of turbines
of the design suggested in this article.
On this design corresponding applications for the invention are sent.
Article is offered in English in a format html, the version for a printing
– in a format Microsoft Word
and in a format PDF.
The table Excel (458 êB) with detailed aerodynamic calculations of the traditional turbine with rated power 4.5 MW and diameter
120 m (a sheet 1 - for comparison) and similar calculations of the turbine of a new design (a sheet 3) is added to the article. Detailed
calculations of annual gathering of wind energy by the mentioned traditional turbine
and the turbine of new type for areas with 4, 5, 6
and 7 wind classes (mid-annual speeds of a wind 5,8; 6,2; 6,7 and 8,2 m/s accordingly) and parameters Weibull K – 1,5; 2 and 2,5 for
every wind speed is offered in same table (sheets 2 and 4). Access to formulas
of calculations in the table is free, there are evident
diagrams.
The submitted technique of calculations is unique itself, evident and it will be interesting
not only to experts in the field of
aerodynamics and in the field of forecasts of annual gathering of wind energy, but also to people beginning acquaintance of
aerodynamics
or wind energetic.

of wind industry. Some known international information resources refer to this page
as to the directory about the companies of the wind industry.
New
In June 2008 on a site the second part of article is published. In it the detailed technique of aerodynamic calculations of the wind turbine is offered. To a technique
the example of calculation (table Excel - 277 kB) a rotor of the wind turbine in diameter
of 240 m by power 120 MW is applied. For those who liked article and calculations,
