Description

Technical Field

[0001] The utility model relates to the technical field of storing and releasing electric energy, in particular to a magnetic suspension breeze generator. Background Art

[0002] The working principle of the magnetic levitation wind turbine is that the whole or part of the shaft system of the generator is suspended in space through magnetic bearings, the wind drives the blades and the whole shaft system to rotate, the mechanical energy is converted into electrical energy through the generator, and finally the electrical energy generated by the generator is converted into usable electrical energy through the power electronic converter. In addition to the advantages of energy saving and environmental protection, the most important features of the magnetic levitation wind turbine are low starting wind speed (1.5-2.5m / s); stable operation, no noise, long service life; low space requirements, can be used in urban areas, suburbs, coastal mountainous areas, according to the relative position of the wind shaft and the ground, the magnetic levitation wind turbine is divided into horizontal axis wind turbine and vertical axis wind turbine. Due to the many advantages of vertical axis wind turbine, it has been widely developed in recent years.

[0003] Traditional wind turbines need to transmit power through direct contact between the blades and the shaft. The friction in the generator causes energy loss and low power generation efficiency. In addition, due to the constant change in wind speed in nature, the output of the wind turbine also changes at any time. When the wind speed is greater than the cut-in wind speed, the wind turbine starts to run on the grid; when the wind speed is lower than the cut-in wind speed, the wind turbine shuts down and disconnects from the grid. Therefore, the output of the wind turbine is highly random, and there may be multiple starts and grid connections and shutdowns in a day. In areas with large wind power installed capacity, the fluctuation of wind power has a certain impact on the frequency of the power grid, so a magnetically suspended micro-wind generator is needed to improve the above problems. Utility Model Content
