The first
2000kW Wind Turbine Generator in Japan starts operation at Okinawa. |
|
MWT-S2000, the largest wind turbine generator in Japan, started operation in Okinawa.
This wind turbine generator was installed by MHI for Okinawa New Energy Development
Company, Inc. on January 24, 2003, into the premises of Gushikawa Power Station
owned by the Okinawa Electric Power Co, Inc. The electricity supplied by this
wind turbine generator is delivered to The Okinawa Electric Power Co., Inc.
The MWT-S2000 is the largest Japanese wind turbine generator rated at 2000 kW,
and is the first 2000kw class wind turbine generator designed and built by non-European
wind turbine manufacturer.
Also, it is the first and largest commercial wind turbine generator equipped with
a permanent magnet synchronous generator in the world. MHI, in cooperation with
Mitsubishi Electric Corp. overcome all difficulties in designing and manufacturing
larger capacity wind turbine generator, with new light weight blades, small size
generator and inverter, and other improved technologies.
This wind turbine generator is a variable speed gearless synchronous type and
designed in accordance with IEC-61400 Class-1, and is capable of bearing violent
typhoons frequently assaulting Okinawa. It is featured by:
| 1. |
High-quality electricity; Variable speed synchronous wind turbine generator
delivers high-quality electric energy by leveling off changes of output due to
the breathing of wind. |
| 2. |
High efficiency; the wind turbine operates at an optimal rotating speed to
the wind speed. |
| 3. |
Reliability and Maintainability; The gearless and permanent magnet wind turbine
generator that is simple in structure and free of wearing parts, contribute to
high reliability and maintainability.
On February 6, the New Energy Foundation in Japan granted MHI and Mitsubishi Electric
“the Minister of Economy, Trade and Industry Prize - 7th New Energy Award
-“ for their excellent technologies incorporated in this synchronous wind
turbine generator system. |
