| 摘 要： | 针对电气化铁道牵引供电系统存在大量的负序、谐波、无功等问题,提出了基于平衡变压器的背靠背SVG补偿方案.方案中综合潮流控制器装置主要由两个背靠背的单相二极管箝位型三电平电压源变流器构成,主要用于传递有功功率、补偿无功功率及谐波,使得牵引供电系统相对电力系统而言,是一个三相对称纯阻性网络.以实测牵引负荷作为给定负荷进行仿真验证,结果表明,该方案能实时动态地补偿电气化铁道谐波、无功和负序电流,改善电气化铁道电能质量.

| Abstract: | According to the problems of negative sequence,reactive and harmonic that caused by traction power supply system,back-to-back SVG compensation scheme based on balance transformer is proposed.Comprehensive power flow controller is composed of two back-to-back single-phase diode-clamped three-level voltage source converter.It mainly transfers the active power,compensates the reactive power and harmonic current simultaneously,making the traction power supply system is a three-phase symmetrical pure resistant l... |
