D. Nemykina, O. V. Andrienko, A. A. Mokhnach, R. E. induction feed system trolleys feed bus current distribution power and voltage losses система індукційного живлення тролея шина живлення розподіл струму втрати потужності та напруги Purpose. Investigation of the influence of higher harmonics of current on current distribution, voltage and power losses in the supply systems of crane trolleys and development of a calculation method for practical use. Methodology. The analytical method and the results of the modeling method were used for research. Results. Analytical relationships have been obtained that make it possible to determine the current distribution, voltage and power losses in the systems of induction feeding of crane trolleys, taking into account the composition and amplitude of the higher harmonics of the current. Originality. For the first time, analytical dependences are obtained that take into account the effect of changing the trolley parameters on the frequency in the feed systems. Numerical values have been determined for the most commonly used induction feed systems for cranes. It is shown that with an increase in the cross-section of the feed bar there is a decrease in the main, and especially additional, losses. Practical value. Theoretical relationships have been obtained that can be used to calculate the optimization of induction feed systems in the presence of higher harmonic currents arising in power systems during operation of crane semiconductor controlled electric drives. У статті викладена методика розрахунку розподілу струму по струмопроводам, втрат напруги і потужності з урахуванням вищих гармонік струму в системах живлення кранів з індукційним підживленням. Отримані необхідні аналітичні залежності, що пов’язують параметри струмопроводів з відносними значеннями частоти вищих гармонійних і визначають їх вплив на струморозподіл, втрати напруги та потужності. Показано, що зі збільшенням перетину шин підживлення відбувається зниження втрат напруги і додаткових втрат, в тому числі і від струмів вищих гармонік, за рахунок перерозподілу цих струмів і втрат від них в шину подачі, що має практично незалежний від частоти активний опір. Показано, що основна частина додаткових втрат визначається амплітудами гармонік з порядком n≤7. Методика може бути застосована для систем живлення залізничного транспорту і розподільних систем, виконаних з застосуванням сталемідних і сталеалюмінієвих струмопроводів.
