Chenchevoi V. Standalone unregulated induction generator with high saturation magnetic system

Object of research - process of energy conversion in the autonomous uncontrolled AG with highly saturated magnetic system. Subject of research - modes and features autonomous uncontrolled AG with highly saturated magnetic system. The aim of the work is to improve the definition of loss techniques of the steel by taking into account real processes of magnetization reversal in the autonomous uncontrolled AG with highly saturated magnetic system in the formation of an autonomous power supply units available on the technological facilities of asynchronous motors. Theoretical results: improved method for determination of iron losses autonomous uncontrolled AG through additional accounting stream lag from a magnetizing current due to the influence of the domain structure of a ferromagnetic material, which, in contrast to the existing methods allows to analytically explore the dynamic regimes of magnetization reversal with a high saturation magnetic system (k? = 2...3); the first time an analytical dependence for determining losses in the steel autonomous uncontrolled AG, as the ratio of the product rate, depending on the properties of steel, depending on the square of the EMF from the magnetizing current to the derivative of this relationship, which allows you to take into account the peculiarities of the rapid growth in the high-saturation loss; for the first time determined the effect of iron loss at high saturation on the characteristics of its autonomous uncontrolled AG in a permissible range of variation of the size and nature of the load, which allows to calculate the allowable load capacity of the generator, and while it is running on overload. Bottom Line: The developed regression model AG taking into account losses in the steel to evaluate the effect of variation in the quality parameters of the generator self-excitation process in the determination of the main and marginal modes of autonomous uncontrolled AG; The dependences suitable for practical finding the iron loss in the high-saturation mode, which allows to forecast the maximum overload capacity of autonomous uncontrolled AG and can be used in devices of a functional diagnosis in determining the permissible time for overload operation.
