Problems solved by technology

[0004] However, the power level of the existing vertical axis wind turbines is not high. The reason is that most of them adopt the structure with the rotating shaft at the center, and the blades are fixed on the rotating shaft. This structure has a small wind collection area, which limits the utilization of wind energy, making the generator heavy Low power, high cost

Abstract

The invention relates to a vertical axis suspension permanent magnet wind generator and a control method of the vertical axis suspension permanent magnet wind generator and belongs to the field of wind power. The wind generator comprises a rotor, a stator, a shell, a tower cylinder, a base, a damping brake system, a suspension system, a wind collection drive system and a control system. The stator comprises a stator core and a three-phase winding. The periphery of the tower cylinder is sleeved with the stator, and the stator and the tower cylinder are fixed. The rotor comprises a rotor core and a permanent magnet, and the outer side of the stator is sleeved with the rotor. The suspension system is an electromagnet and permanent magnet mixed suspension system. The wind collection drive system comprises transverse supports, longitudinal supports, blades and sleeves. The transverse supports and the longitudinal supports are fixed to the rotor and the shell. The control system obtains the suspension current given value according to the difference of the air gap length set value and the air gap real-time measurement value to control the suspension air gap, and the stable power generation of an engine is guaranteed. The vertical axis suspension permanent magnet wind generator is ingenious in structure, easy to control, easy and convenient to mount and maintain, high in wind energy utilization rate and capable of achieving the low-wind-speed start and large-power output.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a vertical axis suspended permanent magnet wind power generator and a control method thereof, belonging to the field of wind power. Background technique [0002] At present, the mainstream products of high-power wind turbines are horizontal axis wind turbines. However, horizontal axis wind turbines have inherent defects such as needing yaw to face the wind, low utilization rate of wind energy, complex and difficult control, unchanged installation, and high cost, which affect their healthy development. [0003] The vertical-axis wind turbine can overcome the above defects. It does not need to face the wind, and has the advantages of high utilization rate of wind energy, simple control, and easy installation. It has been applied in vertical-axis wind turbines with small and medium power levels. [0004] However, the power level of the existing vertical axis wind turbines is not high. The ...
