摘要：

为解决SS4B电力机车检修牵车移库作业时所用设备多、操作烦琐、效率低等问题,研发一套车载电力机车牵车移库专用电源系统。设计以数字信号处理器(DSP)TMS320F28335芯片为核心的机车应急电源控制系统;系统主电路由碳化硅(SiC)功率器件搭建充电单元与两级直流转直流(DC/DC)斩波单元,并搭配超级电容储能装置,依托DSP输出脉冲宽度调制(PWM)波形,完成全系统功率器件驱动控制。结果表明:两级DC/DC斩波模块与超级电容储能单元协同运行,可输出直流(DC)70~130 V连续可调的直流电压,整套功率变换单元的转换率达93% 以上;该输出特性可稳定驱动机车牵引电机低速运行。其中,充电模块具备宽范围接触网电压适配能力,可实现恒流、恒压分段式快速充电,满足机车应急储能需求。经装车试验验证,实现了无接触网工况下机车应急供电自驾牵车移库的设计目标。

Abstract:

To tackle the problems of excessive auxiliary equipment, complicated operation, and low efficiency during shunting and depot transfer of SS4B electric locomotives for maintenance, an on-board dedicated power supply system for electric locomotive shunting and depot transfer was developed. A locomotive emergency power supply control system based on DSP TMS320F28335 chip was designed. The main circuit of the system adopted SiC power devices to construct the charging unit and two-stage DC/DC chopper unit, which was integrated with a supercapacitor energy storage device. The high-speed DSP controller generated pulse width modulation (PWM) waveforms to realize driving and control of all power devices in the whole system. The results show that the coordinated operation of the two-stage DC/DC chopper module and supercapacitor energy storage unit can provide continuously adjustable DC output voltage ranging from 70 V to 130 V, and the conversion efficiency of the entire power conversion unit exceeds 93%. Such output performance can steadily drive the locomotive traction motors to operate at low speeds. The charging module features wide catenary voltage adaptability and supports segmented fast charging with constant current and constant voltage to meet the emergency energy storage demands of locomotives. Vehicle-mounted tests verify that the design target of self-propelled shunting and depot transfer with locomotive emergency power supply under catenary-free conditions can be fully achieved.

Key words: electric locomotive, emergency power supply, shunting and depot transfer, charger, supercapacitor, direct-current-to-direct-current (DC/DC) chopper, digital signal processor (DSP) control system
