Description

Gyro type wind turbine magnetic suspending wind turbine generator

Technical field

The utility model relates to a kind of wind power plant, belongs to field of generating equipment, especially a kind of gyro type wind turbine magnetic suspending wind turbine generator.

Background technique

Wind power generating set is comprised of wind wheel, transmission system, yaw system, hydraulic system, braking system, generator, control and safety system, cabin, pylon and basis etc.Using wind-driven generator, is exactly continuously wind energy to be become the standard civil power that our family uses, and the degree of its saving is significantly, and the electricity consumption in 1 year of one family only needs the cost of 20 yuan of acids.The permanent magnet suspension wind-photovoltaic complementary power generation system has been invented by China, and wind-power electricity generation is used for illumination.Be all developing country, India's wind-driven generator electric motor power is that China is more than 3 times.The wind wheel that slowly runs by transmission system by the step-up gear speedup, with transmission of power to generator, thereby making wind energy transformation is mechanical energy. whole cabin is lifted by tall and big pylon, because wind vector is indefinite, so in order effectively to utilize wind energy, wind plant is housed also, the wind direction signals that can record according to wind transducer, by controller control yaw motor, the pinion rotation of gearwheel engagement makes the cabin all the time facing the wind on driving and the pylon.What be equipped with from net type wind-driven generator all is the three-in-one inverter controller of wind light mutual complementing, and it has the function of rectification charging, off-load and inversion output.The unsettled AC rectification that generator is sent becomes direct current to charge a battery, play simultaneously and prevent accumulator super-charge, cross put, the effects such as overload and short circuit; Provide unloading channel to generator, with protection battery and generator; At last direct current is converted into stable Ac and uses to the user altogether, and do not need other any change and special devices, can link to each other with solar opto-electronic board by the wind light mutual complementing inverter controller, reach maximum, the most stable renewable energy sources of utilizing.What the grid type wind-driven generator was equipped with is combining inverter, and it adopts the auto-optimization technology that the efficient of generator is improved greatly, can be higher than 80%, and LCD and light-emitting diode display are arranged, and can understand intuitively, all sidedly working order etc. characteristic advantage and the effect of blower fan.Should be noted that, at the abundant area of wind resource, the wind-driven generator of preferably selecting blower fan rated designs wind speed and local optimal design wind speed to match.No matter be from the selection of wind energy conversion system if accomplish this point, still utilizing on the economic implications of wind resource has important meaning.Wind tunnel test proves, cube being directly proportional of the transfer power of wind wheel and wind speed that is to say that wind speed is maximum to power influences.For example, in the area that local optimal design wind speed is 6m/s, the wind-driven generator that the rated designs wind speed is 8m/s is installed, specified output power only reaches 42% of former design output power its year as a result, that is to say that the wind-driven generator rated output power has reduced by 58% than design load.Should from power device, take out for long-term no battery as far as possible.

The working principle of magnetic suspending wind turbine generator is: adopt magnetic levitation technology, the magnetic force of combining super magnet is suspended in certain space with motor coil, in the situation without any mechanical friction, rely on Wind power propelling electric machine rotation and cutting magnetic line to send Ac, and be stored in the battery.Than traditional horizontal axial type wind-driven generator, although the magnetic suspending wind turbine generator cost is higher, its advantage is very outstanding: the first, and the former must change the rotation windmill by box haul with empennage; The latter relies on the rotation of the gyro type wind wing, and box haul does not change and changes the axle center.The second, the former noise is large, can't overcome variable wind to the shake that brings, and motor, blade come off easily, and palpus was changed an accessory in 3 years; And that the latter is turned round is stable, noise free, and various parts life-spans are long, difficult drop-off, but continuous operation is more than 20 years.The 3rd, the former requires spacious unsheltered large space; And the latter is low to spatial requirement, and no matter urban district, suburb, coastal mountain area are all available; At last, also be the most important, the former starts at least 2.5m/s of wind speed, and the latter only needs the 1m/s wind speed to start, and wind speed surpasses 40m/s and also can as usual turn round, and the higher generating efficiency of wind speed is higher, and generated energy is comparable, and the former increases by 35%.

Have in the market ripe magnetic suspending wind turbine generator, basic functional principle is identical.Magnetic suspending wind turbine generator is to adopt magnetic levitation technology, the core technology of the power of reducing friction realizes generating, at present adopt the designs such as the wind wings, fan blade but the on-stream axle center that all exists is unstable more, be subject to easily wind direction impact and generation extra friction, have influence on generating efficiency.
