Оптимізація керування мотор-вентилятором охолодження тягових двигунів вантажного локомотива з асинхронним тяговим приводом при русі на ділянці з заданим профілем та графіком руху

Abstract

Робота присвячена розробці методики оптимізації керування мотор-вентилятором тягових двигунів вантажного локомотива з асинхронним тяговим приводом при русі на ділянці з заданим профілем та графіком руху. Особливістю методики є таке: методика основана на розв’язанні задачі умовної мінімізації за критерієм економічної ефективності системи вентиляції та охолодження методом Вейля за узагальненим золотим перетином. The work is devoted to the development of methods for control optimization of the motor-fan of traction engines of a freight locomotive with an asynchronous traction drive when moving to sections with a specified profile and traffic schedule. The peculiarities of the methodology are the following: the method is based on the solution of the problem of conditional minimization by the criterion of the economic efficiency of the ventilation and cooling system by the Weyl method over the generalized golden section; as the optimization parameters, the following values are chosen: the temperature of the motor-fan on and the number of pole pairs of the motor-fan motor, and inequalities are also established; The task of analyzing the ventilation and cooling system of traction motors is based on modeling the thermal conditions of an asynchronous traction motor according to the generalized equivalent thermal scheme.
