Research on DC Railway Vehicle for Voltage Stabilization of Electric Railway Substations Using Operation Data-Based Control Strategy

This paper aims to stabilize substation voltage by using railway vehicles as voltage stabilization resources. By minimizing catenary voltage fluctuations, the stress on electrical components is reduced, and issues from overvoltage and overcurrent during train operation are mitigated. The research proposes a hybrid control structure combining model-based and data-based approaches, utilizing operation data. PSCAD-EMTDC and C language interface aided simulations shows the effectiveness of the control strategy in reducing voltage fluctuations and optimizing train operation patterns. This study offers a novel method for enhancing voltage stability and operational efficiency in railway systems.
