The invention provides a double-stator double-convex large-power generator, which relates to the technical field of high-power wind generators and wind power hydrogen production. The outer side of the inner stator is provided with inner stator tooth poles and inner stator windings, and the inner side of the outer stator is provided with outer stator tooth poles and outer stator windings; the inner side of the rotor is provided with rotor inner tooth poles, the outer side is provided with rotor outer tooth poles, and the rotor inner tooth poles and Magnetic isolation plates are arranged between the outer teeth and poles of the rotor. The number of poles of the outer stator, rotor and inner stator is set to 6N / 4N / 6M / 8M poles, among which N≥4, M≥1, M and N are positive integers; the outer stator, rotor and outer stator windings constitute the outer stator. Generator; the inner stator, rotor and inner stator winding constitute the inner generator. The invention has the characteristics of large output power, wide power range, high utilization rate of wind energy, high output power quality, simple and compact structure, and small occupied space. It is a wind turbine especially suitable for off-grid / grid-connected wind power to produce hydrogen.
Description
technical field [0001] The invention patent relates to the technical field of hydrogen production by wind power. Background technique [0002] The 21st century is an era of high-efficiency, clean, safe, economical and sustainable use of energy. All countries in the world also regard the use of energy as the key to scientific research. Wind power hydrogen production technology is a new type of environmentally friendly hydrogen production technology that uses wind power generators to generate electricity and directly apply it to electrolyzed water to produce hydrogen through simple processing. Domestic wind power hydrogen production technology started relatively late, and there are relatively few studies on wind power hydrogen production. In terms of related projects and projects in my country, in 2008, China Urban Planning and Design Research Institute proposed the construction pattern of seawater desalination hydrogen production base. In 2013, Guodian United Power Technolo...
