Разработка электропривода для эскалатора мощностью 160 кВт

Abstract

В данной работе изложен процесс моделирования электропривода эскалатора на базе Mathlab в среде Simulink. Даны общие понятия и классификация эскалаторов. Произведен сравнительный анализ существующих моделей эскалаторов. Выбран эскалатор, чья мощность двигателя подходит под поставленную задачу. На основании параметров эскалатора, его основных нагрузок, рассчитан редуктор и выбран электродвигатель и приведены его паспортные параметры, включая паспортную механическую характеристику. Проведен расчет параметров схемы замещения электродвигателя эскалатора. Дано определение частотному регулированию. Проведен расчет и настройка тормозного модуля в звене постоянного тока. Изучена технология моделирования систем управления электродвигателем. Разработана корректно функционирующая модель электропривода эскалатора, включающая в себя источник трехфазного переменного напряжения, выпрямитель, звено постоянного тока с тормозным модулем, инвертор, электродвигатель мощностью 160 кВт и систему управления инвертером. Также было составлено подробное описание принципа работы модели. Проведены испытания, необходимые для отладки модели и поиска возможных ошибок. Приведены результаты работы модели в виде осциллограмм работы электродвигателя.

This work describes the process of modeling an escalator electric drive based on Mathlab in the Simulink environment. General concepts and classification of escalators are given. A comparative analysis of existing escalator models is made. The escalator 4 whose engine power is suitable for the task is selected. Based on the parameters of the escalator, its main loads, the gearbox is calculated and the electric motor is selected and its passport parameters are given, including the passport mechanical characteristics. The parameters of the escalator electric motor replacement scheme are calculated. The definition of frequency regulation is given. The calculation and adjustment of the brake module in the DC link is carried out. The technology of modeling electric motor control systems is studied. A properly functioning model of the escalator electric drive has been developed, including a three-phase AC voltage source, a rectifier, a DC link with a brake module, an inverter, a 160 kW electric motor and an inverter control system. A detailed description of how the model works was also compiled. The tests necessary for debugging the model and searching for possible errors were performed. The results of the model operation are presented in the form of oscillograms of the motor operation.
