Abstract

In addition to obtaining necessary dynamic characteristics and broadly using modern solid-state traction converters, intensified electric rolling stock (ERS) traffic flow and increased travel speeds have a significant influence on the catenary system and cause voltage dips and surges. This article considers the possibility of stabilizing the voltage of a catenary system section by means of an automatic voltage stabilizer that uses the energy accumulated in an electricity storage device. This stabilizer is designed as a reversible solid-state converter used to charge and discharge the energy storage device. The proposed formulas are used to make up a mathematical model the main strength of which is the usage of real data collected from urban ERS traffic flows. The test results show that a voltage stabilizer using the energy of the storage device can reduce the influence of ERS on the catenary system voltage.

电动车辆接触网系统的自动稳压

摘要

除了获得必要的动态特性和广泛使用现代固态牵引变流器外，电力机车车辆 (ERS) 交通流量的增加和行驶速度的增加对接触网系统有重大影响，并会导致电压骤降和浪涌。本文考虑了通过使用蓄电装置中积累的能量的自动稳压器来稳定接触网系统部分电压的可能性。该稳定器设计为可逆固态转换器，用于对能量存储设备进行充电和放电。所提出的公式用于构成一个数学模型，其主要优势是使用从城市 ERS ​​交通流中收集的真实数据。
