WORLD WIND ENERGY NET

1•  Use

This wind-generating set makes from Worldwind Turbine Factory, use of natural wind as power, wind vane absorbing the wind energy to making the wind generator turning,and then covert the wind power into electric energy, AC being covert into DC through rectification and manostate of the controller, the accumulators battery being charged and the electricity being stored. In this way DC load can be directly used or inputted into inverter becoming sinusoidal AC of 220V/50Hz or 110V/60Hz for use of daily lighting etc.

2. Characteristics

WW series wind-generating set manufactured by our company has nine characteristics as follows:

•  Low start-up wind speed is needed. High system efficiency. Little flutter in operation. Lower noise. Small and nice looking. Easy installation and maintenance.

•  New output electrical output eliminates the trouble of cable twist when in windward which often happens in traditional small wind energy conversion system (WECS).

•  The connecting device of human nature facilitates the installation, maintenance and repairmen of the electricity system.

•  The blades of wind rotor are made of new type of material through new technique of precise injecting-molding and optimizing air-actuated shape and structure design, which makes the high energy coefficient of wind use and low material-consumed for per 100w electricity under the same wind-swept area.

•  For AC generator the patent of p-m rotor magnetic circuit with special stator is adopted, which effectively reduces drag torque of the generator, makes a better match between the wind rotor and the generator, enlarges the effective wind-speed scope, thus increases the annual energy output.

•  The new device of magnetic brake, designed in accordance with the charactetistic of the generator itself, simplifies the structure and improves the reliabilities of the operation.

•  Strategy of microcomputer controlling is adopted for the wind-generating set. The electronic converter forms a system of rectification, stabilivolt and trouble-controlling and trouble-indicating, which solves the long-puzzling problem of incorporation of rectification and stabilivolt in the small–size wind energy conversion system (WECS). It has the alarm function to indicate troubles such as overcharge or lower-voltage of the accumulator ,etc to protect itself automatically. With the ready input termind button for the hotovoltatic battery, user can easily change it into wind-solar complementary power system 。

•  The damping device not only ensures the sensitivity of following windward and the stability of the adjusting direction but also avoids the fluttering of the set to result in decreasing of generating capacity due to of the frequent change the orientation of wind.

•  The aptitude sinusoid inverter converts the DC into AC of 220V/50Hz or 110V/60Hz, which suitable for the inductive loading and has the function of automatic protection against short circuit, overloading and accumulator set's overdischarge and overcharge, thus prolongs the life of the accumulator battery.
