自耦变压器供电方式的电牵引供电系统中的机车驱动谐波污染仿真研究

为了减少电气化铁路对其沿线的通信系统造成的干扰 ,电牵引供电系统可以采用自耦变压器供电方式。本文分析了此系统中的机车驱动谐波污染情况 ,建立了 SS4型电力机车、牵引网及牵引变电所的模型 ,并通过 MATLAB仿真计算出在多机条件下电力机车。

电牵引供电系统短路计算机辅助分析

根据电牵引供电系统故障的对称分量统一解析法及不对称短路计算的正序等效定则，形成一个通用等效复合序网，以运算曲线法，建立牵引供电系统中发生短路后任意时刻网络中任一处电气量的机辅分析计算的一套数学模型，并给出程序设计框图。

Quasi Dynamic Model of Wheel Vehicle with Electric and Hybrid Drive System

The paper presents physical and mathematical models of kinetic system, drive system （electric and combustion traction motors）, and also wheel and rails traction vehicle supply system （car, special vehicle, modern tram vehicle）. Selected predictive and quasi dynamic control system algorithms of traction vehicle are presented in the paper. For selected constructions of traction vehicle drive system are presented in simulation models and are results of calculations of different exploitations work state of wheel vehicle with hybrid drive system. Results of computer calculations are verified with laboratory measurement and suitable corrections coefficient to simulations models of vehicles is introduced.
