摘要

牵引负荷与铁路牵引电网谐振的相互作用会影响牵引系统的稳定性。本文介绍了一种应用于牵引系统的电共振不稳定性研究。通过实例分析了牵引段长度和变流器延时对牵引系统稳定性的影响。基于阻抗的牵引系统表示用于识别共振和分析稳定性问题。PSCAD/EMTDC时域模拟也验证了稳定性研究。

Electrical resonance instability study in traction systems

Traction system stability can be affected by the interaction between the traction load and resonances in the railway traction grid. This paper presents an electrical resonance instability study applied to traction systems. The influence of traction section length and converter time delay on traction system stability is analyzed with examples. An impedance-based representation of the traction system is used to identify the resonances and analyze stability problems. PSCAD/EMTDC time-domain simulations are also shown to validate the stability study.
