Description
Technical field
The present invention relates to a kind of magnetic suspension vertical shaft wind-driven generator of outer-rotor structure, specifically is a kind of five-freedom degree full-suspension vertical shaft wind power generator of outer-rotor structure, belongs to technical field of wind power generation.
Background technique
The principle of wind-power electricity generation is to utilize wind-force to drive the generator amature rotation to produce electric energy, by different generation modes are compared, can find that wind-power electricity generation is the green electric power supply on the complete meaning---pollution-free, renewable, nexhaustible.The wind energy amount of accumulateing in the whole world is huge, is about 2.74 * 109MW.Available wind energy is about 2 * 107MW, is about 10 times that developable water on the earth can total amount.THE WIND ENERGY RESOURCES IN CHINA is abundant, and the wind energy content that can develop is about 1,000,000,000 kW, and wherein, the land wind energy content is about 2.53 hundred million kW (liftoff 10m height), but the wind energy content of sea development and utilization is about 7.5 hundred million kW.Pay attention to today of energy-conserving and environment-protective in countries in the world, wind-power electricity generation is to improving ball ecological environment, and reducing atmospheric pollution has very positive effect, and the research and the application of wind-power electricity generation also all more and more paid attention in countries in the world.
In wind-power electricity generation; the wind energy that can be used to produce electric energy is between the incision wind speed and shuts down wind speed section between the wind speed; reduce and start wind speed and cut the utilization that wind speed just can increase available wind energy; just can under identical wind speed, produce more electric energy, thereby can utilize wind-force to generate electricity more fully.But, when the design wind-driven generator, in order to obtain lower incision wind speed, have to reduce the output power of wind-driven generator, in order to solve this contradiction, people have been applied to magnetic levitation technology in the supporting of wind power generator rotor, replace traditional mechanical bearing with magnetic suspension bearing, do the frictional force that not only can significantly reduce between rotor and bearing like this, friction torque, realize " the light breeze starting; breeze wind " of wind-driven generator, enlarge the utilization ratio of wind resource, improve generating efficiency, can also exempt the high cost of mechanical bearing operation and maintenance in the past, reduce cost of wind power generation, this not only helps the development of popularizing of China's wind-power electricity generation and wind-powered electricity generation cause, and China's enforcement energy-saving and emission-reduction work is played important impetus.
Difference according to blade shaft, wind-driven generator can be divided into horizontal axis wind-driven generator and vertical axis aerogenerator, horizontal axis wind-driven generator is that development both at home and abroad is maximum at present, the most common also is the most ripe a kind of wind-driven generator of technology, its starting torque is bigger, the power coefficient height, but in order to make wind wheel all the time over against wind direction, the wind-driven generator of the type need be equipped with device for regulating direction.The blade of horizontal axis wind-driven generator is in the process that rotates a circle, be subjected to the comprehensive function of inertial force and gravity, the direction of inertial force changes at any time, and the direction of gravity is constant all the time, what blade was suffered like this is exactly an alternate load, and this fatigue strength for blade is very disadvantageous.In addition, the generator of horizontal axis all places tens meters high-altitude, and this has brought a lot of inconvenience for the installation and maintenance maintenance of generator.The stressing conditions of the blade of vertical axis rotor in the process of rotation is good more than horizontal axis, because the direction of inertial force and gravity is constant all the time, suffered is a permanent load, so fatigue life is than the length of horizontal axis.Simultaneously, the generator of vertical shaft can be placed on the bottom or the ground of wind wheel, be convenient to installation and maintenance, but vertical axis aerogenerator exists starting performance poor, the shortcoming that starting wind velocity is high, this has limited its extensive use in wind power generation field, in order to address this problem, one adopts the magnetic suspension bearing technology that generator amature is suspended to reduce the suffered frictional force of rotor, improves the starting performance of generator.Whether controlled according to suspending power, magnetic suspension bearing can be divided into passive-type and active two types.The passive-type magnetic suspension bearing mainly utilizes repulsion intrinsic between the magnetic material or suction (between permanent-magnet material, between permanent-magnet material and the soft magnetic material) to realize the suspension of rotating shaft, and it is simple in structure, and power loss is few.Active magnetic suspension bearing mainly is a stable suspersion of realizing rotating shaft by the magnetic force between the ACTIVE CONTROL stator and rotor, the complete active magnetic levitation bearing system of one cover is made up of magnetic suspension bearing body, displacement transducer, controller and power amplifier usually, set up the difference of mode according to bias magnetic field, active magnetic suspension bearing can be divided into full electromagnetic type and electromagnet and permanent magnet hybrid type.The bias magnetic field and the controlling magnetic field of full electromagnetic type magnetic suspension bearing produce by electromagnet; Electromagnet and permanent magnet hybrid magnetic suspension bearing adopts permanent-magnet material to set up bias magnetic field, can reduce the power loss of magnetic suspension bearing largely.
