wind power

Wind power is the conversion of wind energy into useful form, such as electricity, using wind turbines. At the end of 2006, worldwide capacity of wind-powered generators was 73.9 gigawatts; although it currently produces just over 1% of world-wide electricity use, it accounts for approximately 20% of electricity production in Denmark, 9% in Spain, and 7% in Germany.Globally, wind power generation more than quadrupled between 2000 and 2006.

Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology), wind energy is used to turn mechanical machinery to do physical work, such as crushing grain or pumping water.

Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations.

Wind energy is plentiful, renewable, widely distributed, clean, and reduces toxic atmospheric and greenhouse gas emissions if used to replace fossil-fuel-derived electricity. The intermittency of wind seldom creates insurmountable problems when using wind power to supply up to roughly 10% of total electrical demand (low to moderate penetration), but it presents challenges that are not yet fully solved when wind is to be used for a larger fraction of demand.

Hummer Institute consists of the following four laboratories:

Beijing Beiyuan Generator Lab, Shenzhen Beidi Generator Lab, Anhui Lujiang Amorphous Magnet Lab, and Anhui Lujiang Permanent Magnet Lab.

The institute has a lot of achievements in the fields of amorphous soft magnetic materials, permanent magnetic materials, high and low speed generators; and obtains many patents in aspects of generator magnet circuit and generator structure, etc. The institute has an original deep research on the technology of cutting magnetic line.

Hummer has seven patents. Based on its leading technology, our Hummer generator is made in very small size. For example, our350W generator weighs only 5kg, which is about the weight of a flange used in traditional wind generator for fitting blade rotors. The forever magnetism centrifugal clutch developed by Hummer Research Institute really makes the small wind generator to start with gentle wind. The institute does a careful research on mechanical structure and controller to perfect the whole wind generator system.

Hummer Institute is vigorously researching better wind generators for better making use of wind power more efficiently.
