摘要
城市轨道交通直流牵引供电系统中再生制动已经得到广泛应用。如果使用车载电阻吸收再生能量,会有增加车体重量、隧道温升和浪费再生能量等缺点。地面制动电阻是一种很好的替代装置。结合广州地铁4号线,通过一个全新的系统仿真,对地面制动电阻的容量确定,位置设置等关键问题进行了仿真研究。实际运行结果表明,地面制动电阻工作正常可以很好地防止再生制动失效。
Nowadays, the regeneration braking has been applied widely in URT. Using the resistor in the vehicle to absorb the regeneration energy usually raises problems, such as the increase of the vehicle weight, the temperature rising in tunnel and the energy wasting, while the ground rheostatic braking is regarded as a good method. This paper makes a research about the power calculation and the allocation principle of the ground braking resistor through the simulation of Guangzhou metro Line 4 and argues that this method could prevent the expiration of the regeneration braking.
