VANTAA, FINLAND -- 07/06/09 --
By adding several new models to its offering, The Switch, a
Finnish-based technology company, is the first company to provide a
complete portfolio of permanent magnet based generator packages
specifically designed for maximized wind power generation. The latest
additions include an outer rotor generator, a modern-style 2.5 MW
drive train, and a double-fed option.
VANTAA, FINLAND - July 6, 2009 - The Switch, a provider of
megawatt-class permanent magnet generator and full-power converter
packages for wind power and other new energy applications, now offers
the most complete range of PM packages.
Outer rotor generator - launch of a new platform for easy turbine
integration
The introduction of the newest generator model combines the benefits
of a permanent magnet (PM) and direct-drive solution with an outer
rotor. These PM machines represent the technology of choice for
next-generation wind power generators, as they offer a platform of
highly integrated components that are built to last and require very
little maintenance.
The simple, straightforward design integrates the main shaft, main
bearings, gearbox and mechanical brake into a single generator
"combo". The outer rotor reduces the weight of a direct-drive
application. The generator shares a common bearing with the turbine
itself, and the turbine's brake system has been integrated as part of
the generator. The gain is realized in simplicity, fewer components -
and therefore, higher reliability.
"For newcomers to modern technology in the wind power industry, The
Switch outer rotor generator offers an ideal solution, because it's
the fast-track way to make a high-performance turbine," says
Jukka-Pekka Mäkinen, President and CEO of The Switch. "Our new outer
rotor permanent magnet technology enables the best possible energy
yield in varying wind conditions, thereby maximizing annual energy
production."
"As the industry shifts toward PM technology, The Switch is already
able to offer second generation products," Mäkinen continues. "Our
large direct-driven machines have been successfully operating since
2005, a relatively long time in modern wind power history."
The Switch outer rotor prototypes are currently being shipped to
Chinese Dongfang Electrical Machinery Co., Ltd. (DFEM), a leading
supplier of cutting-edge wind power technology in the Chinese market.
The generator's cast-iron body facilitates high volume production.
The first orders of the outer rotor generator will be installed in
the mountainous region of Mongolia where they will operate in extreme
conditions and at very low temperatures.
2.5 MW redesign - more energy from existing turbine
Another new offering is the redesigned 2.5 MW drive train for
conventional turbines. This PM generator and full-power converter
package has been planned for manufacturers who aim to upgrade their
existing wind turbine offerings without making substantial changes to
their proven designs.
"This modern-style 2.5 MW drive train is based on a growing market
need to take greater advantage of existing turbine technology, but
allowing it to do more with the wind available. In other words, to
maximize the amount of power to energy - which fits perfectly with
our business mission," Mäkinen explains.
Double-fed option with modular power packages
As many wind power turbine manufacturers have selected double-fed
induction generator (DFIG) technology, originally due to lower costs
and preference, The Switch now offers 1.5 MW and 2 MW packages
specifically designed for these manufactures to help them tap into
higher power ratings. The Switch double-fed option comes with modular
power conversion packages and well-matched generators for exceptional
flexibility.
"The Switch is now well-known for its pioneering efforts to establish
permanent magnet solutions as the preferred choice in the industry,"
says Reijo Takala, Vice President, Wind Power. "Yet, we have realized
that turbine manufactures that apply double-fed technology, too, are
searching for ways to improve output performance and take greater
advantage of conditions with limited wind speed variations. The
Switch now can serve these manufacturers with flexible converter and
generator solutions and high component reliability. We have been able
to bring our know-how in world-class wind solutions to deliver
successfully to those who want to stay with the double-fed approach."
About the Switch
The Switch provides unique power conversion systems - power
converters, machines and other electrical equipment needed for
distributed power generation and industrial processes. Customers use
the innovative products and systems of The Switch as part of their
own machines or systems in wind turbines and other renewable energy
applications. The Switch solutions support the battle against climate
change and help to preserve energy resources. www.theswitch.com
