Electric means of transportation have seen a rapid expansion partly due to flexibility to commuters and carbon emission reduction. However, transportation electrification is creating severe power quality problems in the utility grid. A single-phase voltage-source traction converter (VSTC) plays a vital role in high-speed train operation. However, it is partly blamed for injecting instability into the vehicle-grid coupling systems (VGCSs). Therefore, understanding the function of VSTC and complying with various grid codes and technical standards for VGCSs is essential. Furthermore, grid-connected VSTC must comply with strict safety standards, such as IEEE Std. 519 and IEEE Std. 16. However, with hundreds or thousands of literature available, it is difficult to choose an effective control method that meets all the requirements. Consequently, to illustrate a clear picture of the development of effective control strategies, this work review recent control techniques, mainly for harmonics rejection and low-frequency oscillation suppression. Factors affecting grid stability and control performance are first identified and discussed in detail. Then, effective control methods to alleviate the disturbance are elaborated. Moreover, future trends on control strategies for VSTCs considering the recent advancements of artificial intelligence are extensively discussed.

高速列车牵引变流器最新控制策略综述


电动交通方式的快速扩张部分归功于通勤者的灵活性和碳排放的减少。然而，交通电气化正在给公用电网带来严重的电能质量问题。单相电压源牵引变流器（VSTC）在高速列车运行中发挥着至关重要的作用。然而，它也被部分归咎于给车网耦合系统（VGCS）带来了不稳定性。因此，了解VSTC的功能并遵守VGCS的各种电网规范和技术标准至关重要。此外，并网VSTC必须符合严格的安全标准，例如IEEE Std。 519 和 IEEE 标准。 16. 然而，现有的文献有数百或数千篇，很难选择一种满足所有要求的有效控制方法。因此，为了清楚地说明有效控制策略的发展，本文回顾了最新的控制技术，主要用于谐波抑制和低频振荡抑制。首先确定并详细讨论影响电网稳定性和控制性能的因素。然后，详细阐述了减轻扰动的有效控制方法。此外，考虑到人工智能的最新进展，VSTC 控制策略的未来趋势也得到了广泛讨论。
