Feature Introduction of YZ78 1.5、YZ92 2.0 PM direct-driving wind turbine

YZ78 1.5 and YZ92 2.0 PM( Permanent magnet) direct-drive wind generator owns 17 patents, it is first created home and abroad and has the international leading level, and laid a foundation  in developing the lager power PM wind generator in direct-drive type, this series models represent the highest technology level and the future developing direction, this is the real model that the wind park owners can use without worries, and will completely meet the demands of high reliability of using sea wind equipment.

The YZ78 1.5, YZ92 2.0 PM Direct Driving Wind Generating Units developed in our company has the following outstanding advantages:

★ The generating unit adopts PM Direct Driving structure, which completely eliminates all the serious problems of gearbox without abrasion, greatly improved the reliability and lifespan, because there is no speed-increasing gearbox, so in operation there is no easy breakdown of the gearbox and no oil leakage of the speed-increasing gearbox; Beside the soft sound of the blade in operation, there is not any noise

To effect the environment; and this completely solved the high hidden trouble which engine oil of the gearbox needs to be heated by low temperature and to be cooled by high temperature.

★Bring our resource superiority of rear earth (over 50% of the world reserves) used as PM materials into full play. Being competitive in Chinese market first, and then on the world market,  the wind generating unit will have world competition advantage of China, which breaks  technology monopoly of foreign wind generator manufacturer to cut drastically the price of domestic wind generator to reduce the investment burden of downstream wind field owner. Reducing price of wind generator and improve the competition of green energy and international competition of the Chinese wind equipment;

★ Breeze can generate electricity; Sleeplessly adjust generating capacity according to wind speed. The computer controls the output of power, ensuring the wind generator always is under best generating state, compared with the same type of generators home and abroad the generating capacity is 3-5% higher;

★ Strong wind constant power output, automatically adjust blade and speed, constant frequency and pressure. When wind speed is no more than 25m/s, it can generate electricity normally;

★ No need to depend on power network when generating, it can generate dependently, and have the supportive ability when the power network fluctuate accidentally, ensured the power quality and power reliability, effectively avoid the further unreliability of the power network when more paralleled asynchronous generator and double-fed generator are needed

★PM direct-driving wind generator can both be parallel operated and generating independently without grid,

For the place that is far away from electricity network like Sea Island, frontier defense, desert, pasture, no-electricity area can make complementation power supply system with storage battery, diesel electricity, photoelectric, and thus will solve the problem of the power supply.

★We have the computer integrated control system of the whole machine, and this will realize the long-distance supervision and the function of satellite data communication in another field.
