Abstract

Onboard electricity storage units used in hybrid traction power plants allow making electric rolling stock much more energy efficient. To appropriately manage energy flows and efficiently use energy storage units based on various physical operating principles, it is necessary to design bidirectional semiconductor converters that would provide charging and discharging in storage units. This article proposes a circuit design for the power section and the control system, as well as control algorithms for dc pulse converters of onboard electricity storage units for prospective traction electric rolling stock. It is shown by computer modeling that the designed system maintains stability and provides a satisfactory quality of transitional processes in all running modes of traction electric drives.

用于电力运输的混合牵引动力系统的能量转换器

摘要

混合动力牵引电厂中使用的机载蓄电装置使电动机车车辆更加节能。为了基于各种物理操作原理适当地管理能量流并有效地使用能量存储单元，有必要设计将在存储单元中提供充电和放电的双向半导体转换器。本文提出了一种用于预期牵引电力机车车辆的功率部分和控制系统的电路设计，以及车载储能单元的直流脉冲转换器的控制算法。计算机建模表明，所设计的系统在牵引电驱动的所有运行模式下均能保持稳定性并提供令人满意的过渡过程质量。
