Abstract

Grid interaction and stability is an important issue for 16.7-Hz single-phase railway applications. A project is set up which aims to develop an overall control scheme for traction vehicles which stabilizes the grid and avoids generating disturbances and excitation. To analyse the full dynamic behaviour on the firm footing of experimental results, a test bench is built. On the one hand the 16.7-Hz single-phase railway grid is modelled — featuring impedance, grid voltage harmonics and pantograph arcing. On the other hand the full power chain of a traction vehicle is modelled. To simulate such complex structures consisting of networks and components described by high-order differential equations and several power-electronic devices with high accuracy and efficiency as well, an advanced simulation concept is needed. One which fulfils the requirements and convincing simulation results of the interaction between modelled grid and loco are presented. The verification is done by measurements.

铁路网格表示与交流机车动力系模型交互的先进仿真概念

电网的相互作用和稳定性是16.7 hz单相铁路应用的重要问题。建立了一个项目，旨在开发一种稳定电网，避免产生干扰和激励的牵引车辆整体控制方案。为了在实验结果的基础上分析其全动力特性，搭建了试验台架。一方面，对16.7 hz单相铁路电网进行了建模，包括阻抗、电网电压谐波和受电弓电弧。另一方面，对牵引车辆的全动力链进行了建模。要对这种由高阶微分方程描述的网络和部件组成的复杂结构以及多种电力电子器件进行高精度和高效率的仿真，需要一个先进的仿真概念。给出了一个满足要求的模型，并给出了令人信服的模型网格与机车交互的仿真结果。验证是通过测量完成的。
