“…One of the ways to improve energy efficiency is to decrease energy costs in the operation of a traction drive [2][3][4]. The other way is to create traction drives based on the new, promising types of electromechanical energy converters, traction engines, such as induction [2][3][4], reactive inductor [5], and synchronous motors with excitation from permanent magnets [6] (SMPM). The latter possess high energy indicators as a result of the absence of losses for excitation [1].…”

This makes it possible to reduce the capacity of the power plant and use the energy which is stored in the batteries [6]. Despite the higher efficiency of such a transmission compared to traditional, the issue of low efficiency of the power plant remains unresolved.…”

This article describes one of the possible ways for improving the energy efficiency of shunting diesel locomotives. It means a replacing a traditional traction electric transmission with a diesel generator set with a hybrid transmission with a free-piston internal combustion engine and a linear generator. The absence of a crankshaft in an internal combustion engine makes it possible to reduce thermal and mechanical losses, which, in turn, leads to an increase in the efficiency of traction electric transmission of the diesel locomotive.

Дослiджено режими роботи однофазного активного випрямляча струму у випадку широтно-iмпульсної модуляцiї по прямокутно-ступiнчатому закону i навантаження у виглядi тягового двигуна постiйного струму. Розглянуто однофазну мостову схему випрямляча з розрядним дiодом. Розроблено математичну модель випрямляча i визначено основнi розрахунковi спiввiдношення для широтно-iмпульсної модуляцiї при прямокутно-ступiнчатiй формi модуляцiйного сигналу. На комп'ютернiй моделi дослiджено електромагнiтнi процеси при трьох значеннях частоти модуляцiї (900, 1200, 1800 Гц). Встановлено особливостi впливу глибини i частоти модуляцiї на коефiцiєнт потужностi випрямляча i ступiнь спотворення синусоїдальностi форми кривих напруги та струму в мережi живлення. Двигун постiйного струму на сьогоднi залишається основним типом тягового двигуна магiстральних електровозiв змiнного струму напругою 25 кВ, 50 Гц в Українi та в рядi iнших країн. Для живлення таких двигунiв як правило застосовують випрямлячi на дiодах або тиристорах. Разом з тим вiдомо, що перетворювачi на повнiстю керованих напiвпровiдникових приладах забезпечують бiльш високу енергетичну ефективнiсть. Проведенi дослiдження дозволили встановити, при яких значеннях частоти i глибини модуляцiї забезпечується високий коефiцiєнт потужностi (бiльше 0,9) i мiнiмальнi спотворення синусоїдальностi форми напруги i струму в мережi живлення. Це дозволяє визначити рацiональнi пiдходи до вибору силових схем i алгоритмiв управлiння активними перетворювачами в тяговому електроприводi електровозiв. Ефективнiсть пiдвищення коефiцiєнта потужностi i зменшення несинусоїдальностi напруги та струму полягає, насамперед, в зниженнi витрат електроенергiї на тягу поїздiв. За сукупнiстю обраних критерiїв порiвняння найбiльш прийнятним для реалiзацiї в тяговому електроприводi електровоза є активний випрямляч струму з частотою модуляцiї 1200 Гц. Забезпечення високих енергетичних характеристик в широкому дiапазонi тягових навантажень може бути досягнуто в багатозоннiй схемi такого перетворювача Ключовi слова: активний випрямляч струму, коефiцiєнт потужностi, широтно-iмпульсна модуляцiя, математична модель
