【摘要】 城市轨道交通列车运行时广泛采用再生制动方式,再生制动能量回馈至接触网后被附近运行列车吸收,剩余再生制动能量通过再生制动能量吸收装置吸收以限制接触网压过高。目前,再生制动能量吸收装置安装位置主要有列车安装和变电所安装,不同安装位置下,列车再生制动能量引起对直流牵引供电系统的影响不同。分别建立两种再生制动类型下直流牵引供电系统潮流计算模型,仿真分析了多列车多变电所并列运行下,不同位置再生制动能量吸收装置对牵引供电系统电压、电流及再生制动功率分配的影响。更多还原

【Abstract】 Regenerative braking mode is widely used in urban rail transit train,when regenerative braking energy is back to the catenaries,it is absorbed by nearby running trains,and surplus regenerative braking energy is absorbed by regenerative braking energy absorption system to limit the high catenaries voltage. Currently,the installation location of regenerative braking energy absorbing device mainly includes train installation and substations installation. At different installation locations,impact of DC traction power supply system is different. In this paper,two types of DC traction power supply system flow calculation models were established,its parallel operation of multiple trains and multiple substations is simulated and analyzed and the influence of traction power supply system on voltage,current and regenerative braking power allocation under different types of regenerative braking energy absorption systems is obtained.更多还原
