摘要:
本文针对动车组牵引传动系统对电网冲击的影响,分析了牵引传动系统的结构,基于SPWM和瞬态电流控制的单相三电平脉冲整流器结构和控制策略,建立了CRH2牵引传动系统仿真模型,研究了牵引工况和再生制动工况. CRH2牵引传动系统对电网冲击的影响主要有:220 kV网侧电压电流波形和谐波,27.5 kV网侧电压电流波形和谐波,1.5 kV网侧电压电流波形,220 kV网侧功率因数,以及牵引传动系统脉冲整流器不同PI参数. 结果表明,CRH2运行在再生制动工况时,220 kV网侧功率因数接近-1,网侧电流谐波较大,且牵引传动系统脉冲整流器不同PI参数对电网冲击的影响较大. 因此确定合适的脉冲整流器PI参数有助于减小系统对电网冲击的影响,实现电网高频噪声污染治理和动车组安全运行设计.
Abstract:
Aiming at the grid impact of traction drive system(TDS),the structure of the TDS and the structure and control strategy of the single phase three level pulse rectifier based on the SPWM and transient current control are analyzed. The grid impact of CRH2 TDS is studied by employing the proposed the TDS simulation model of CRH2 under traction and braking operation mode,including the voltage and current waveform and harmonic waveform on the 220 kV and 27.5 kV grid side,the voltage and current waveform on the 1.5 kV grid side,the power factor on the 220 kV grid side,and the effect of 220 kV net side current harmonics based on different PI parameters. The simulation results show that the power factor is close to -1 and the current harmonic waveform is high,when the CRH2 operates under the braking operation mode. And with the different PI parameters of the TDS pulse rectifier,the impacts of the grid are very large. The impact of the grid can be reduced by optimizing the appropriate PI parameters,thus realizing the high frequency noises abatement of the grid and the safety operational design of the electric multiple units.
