摘要

在传统的风力涡轮机中,使用机械齿轮箱来传递扭矩。该装置将风力发电机叶片的低转速转化为发电机轴的高转速。机械齿轮箱的特点是可靠性低。它们由旋转的齿轮组成,它们之间的所有扭矩都是通过齿在一点上的接触传递的,这伴随着摩擦。磁乘法器比齿轮减速器更有效。它们不含易损件,具有相对较高的扭矩密度。调制器改变内外转子之间的磁场,从而使旋转速度发生变化。与机械齿轮箱相比,这种装置有许多优点——旋转元件之间的相互作用(扭矩传递)发生在它们的整个区域,而机械齿轮箱的齿轮在它们之间的一个接触点上感知所有传递的力。基于磁齿轮箱的自主风力发电机组的研究是一个相关的研究方向。这将降低运营成本,提高将风能转化为电能的效率,并提高风力涡轮机整体的可靠性。本文的目的是建立混合磁齿轮箱的二维磁场数学模型,以评估其参数和特性并优化其几何尺寸。一种内置磁乘法器的发电机是本研究的对象。磁倍增器在工作时产生旋转磁场,可用于在发电机绕组中感应电动势。这样的发电机比齿轮传动更紧凑,所以在本研究中选择这个选项作为原型。建立了带磁齿轮箱的混合式发电机的几何模型,并建立了数值场数学模型,对其参数和特性进行了分析。在COMSOL Multiphysics软件综合体中对基本发生器的电磁场和特性进行了分析,在此基础上对其几何尺寸进行了优化,优化了质量和尺寸指标

Mathematical modeling of a hybrid magnetic gear for an autonomous low-power wind turbine
In traditional wind turbines, a mechanical gearbox is used to transmit the torque. This device converts the low rotation speed of the wind turbine blades into the high rotation speed of the generator shaft. Mechanical gearboxes are characterized by low reliability. They consist of rotating gears, all the torque between which is transmitted through the contact of the teeth at one point, which is accompanied by friction. Magnetic multipliers are more efficient than gear reducers. They contain no wearing parts and have a relatively high torque density. The modulator transforms the magnetic field between the inner and outer rotor, due to which the speed of rotation changes. This device has a number of advantages over a mechanical gearbox - the interaction between rotating elements (torque transmission) occurs over their entire area, while the gears of mechanical gearboxes perceive all the transmitted force at one point of contact between them. Research of autonomous wind turbines built on the basis of magnetic gearboxes is a relevant direction. This will reduce operating costs, increase the efficiency of converting wind energy into electricity, and increase the reliability of the wind turbine as a whole. The purpose of the work is the development of a two-dimensional field mathematical model of a hybrid magnetic gearbox for the evaluation of its parameters and characteristics and the optimization of its geometric dimensions. A generator with a built-in magnetic multiplier is the object of this study. The magnetic multiplier during operation creates a rotating magnetic field that can be used to induce emf in the generator winding. Such a generator is more compact than a gear drive, so this option was chosen as a prototype in this study. Geometrical models of a hybrid generator with a magnetic gearbox were developed and numerical field mathematical models were developed for the analysis of its parameters and characteristics. An analysis of the electromagnetic field and characteristics of the basic generator was carried out in the COMSOL Multiphysics software complex, on the basis of which optimization of its geometric dimensions was carried out to optimize mass and dimensional indicators
