Subaru
small-scaled wind power generation system
Fuji Heavy Industries
Ltd.
| At the strong request of
local governments and companies, Fuji Heavy Industries (FHI)
developed a 40kW wind turbine. Considering its intended use
in urban areas with comparatively low wind velocities, FHI designed
the turbine so that it would begin generating power at a wind
velocity of 2 m/sec, and reduced the noise level so it could
be installed near residential areas. The aesthetically appealing
design of the wind turbine emphasizes a harmony with the urban
environment in which it will be installed. The system was highly
rated in the aspect of its important contribution to the introduction
of wind power generation in urban areas or areas of low wind
velocity which were previously regarded as unsuitable sites
for the wind power generation. |

Features of equipment, system
and facilities
 |
System |
| • |
The system can be used in many regions because
of its small size, low noise, and capability to generate power
at low wind velocities. |
| • |
It can be installed in areas of low wind near
residential areas where it is readily noticed, so it is ideally
suited to promoting public awareness about the environment
and new energy. |
| |
Effect |
| • |
The turbine will generate 70,000 kWh a year
at an annual average wind velocity of 5 m/sec. |
| • |
This is equivalent to an annual reduction
of 70 tons of CO2. |
| • |
It can be installed in areas previously unsuitable
for wind power generation, so it will make an important contribution
to expanding the reach of natural energy. |
| |
Features |
| • |
High availability rate: The turbine can begin
generating power in low wind speed of 2 m/sec due to its sophisticated
blades and variable speed control, resulting in a high availability
rate. |
| • |
Low noise: It is among the quietest wind turbines
in the world, so it can be installed near residential areas. |
| • |
Simple construction: As the turbine is small,
it can be installed in limited areas where larger turbines
cannot. |
| • |
Excellent power quality: High quality power
can be generated using the turbine’s active pitch,
variable speed control, synchronous generator, and converter/inverter. |
| • |
Attractive appearance: As the winner of the
2001 Good Design Prize, the turbine has an aesthetically appealing
look that blends in well with the Japanese scenery. |
