FOR THE NEXT AGE
The age of low-pressure wind power generators is coming
The amount of power generated by wind power increases in proportion to the square of the radius of the windmill and the cube of the wind speed. It is calculated that if the radius is doubled, the amount of power generated is quadrupled. On the other hand, there are many places where large wind turbines cannot be installed. In particular, Japan is characterized by a narrow land area, steep terrain such as remote islands and mountainous areas, and a harsh natural environment such as typhoons, strong winds, and lightning strikes. In Japan, suitable sites for large-scale wind power generators on land, such as long roads for transporting blades, unloading ports, and maintenance for natural disasters, are limited. On the other hand, small wind power generators (less than 50kw) have the advantage of being able to be installed in places where large wind power generators and weather conditions (rainfall, snow, etc.) make installation difficult for solar power generation. Even if the scale is 50 kW or less, if it is installed in many places such as residential areas, farming villages, and mountainous areas, it will become a large source of energy and lead to environmental measures. In addition, unlike large-scale wind power generators, wind power generators of less than 50kw do not generate low-frequency noise. Therefore, the potential market for small wind turbines is considered to be very large. : Excerpt from NEDO
Souki Co., Ltd. has been working on the wind power generation business in Shizuoka City for a long time. Due to the favorable conditions, we will propose one of the best environments even in Shizuoka City, which has many facilities. Please feel free to contact us if you are interested in wind power generation related to the creation of new energy, not just for investment purposes.
Omaezaki City and Makinohara City, Shizuoka
Omaezaki City and Makinohara City are blessed with the fruits of the mountains and seas and have many power plants.In addition, both citiesWith the best solar radiation and wind conditions, it is suitable for Japan's leading solar power generation and wind power plants, making it an excellent city for storing electricity.
Continuous measurement of wind speed by drone
The strength of our wind power generation is that the same 16-direction anemometer used by the Japan Weather Association is installed on a large drone, and the ground wind speed is 0.2 to 0.5m/s at each site, which is close to no wind. We always measure the wind speed at 30m above the situation so that investors can purchase with confidence in the assumed yield that we present.
As with the 30m tower length of the wind power generator, we hovered for a certain period of time at 30m above the sky and measured the wind speed of 360 degrees. Our company performs simulations based on the Weibull coefficient K/C and altitude data of the Japan Weather Association, but we always use a large drone with an anemometer similar to the one used by the Japan Weather Association at an altitude of 30m. Mounted on and measured. We are doing highly accurate simulations. (Except when it rains or is windy)
Wind speed measurement that can be seen in the video
This is a video measured by a large drone equipped with an anemometer, altimeter, and GPS. If the wind force on the ground is weak, we always measure the wind speed in the sky with a pinpoint point on the north latitude east longitude.

We have completely redesigned Freefly Systems' large-scale drones, which are often used in aerial filming, and have improved them into fully custom-designed drones that are compatible with anemometers.The flight controller is a DJI N3.The altimeter is made by Futaba and is kept at 30m.
