摘要

当高速列车接近嵌入相邻供电臂之间的绝缘分相段时,列车上安装的真空断路器(VCB)必须断开,以保持牵引供电系统处于空载状态,从而完成分相动作。然而,在操作 VCB 时,内部移动触点之间很容易引发电弧,并伴随着过压脉冲。为了探索冲击电流和操作过电压的产生机理,本文基于等效电路建模技术,建立了一个描述 "变电站-轨道车-列车 "牵引供电系统的模型。通过对瞬态变电所运行过程的分析,由于牵引电流的相位角与变电所开关过电压的幅频特性相关,因此牵引电压的相位与变电所接通过电压的特性直接相关。值得注意的是,浪涌电流与牵引变压器的剩磁有关。自动相位切换技术可用于抑制运行过电压和浪涌电流,因为基于粒子群算法,在考虑过电压和浪涌电流平衡的基础上,实现了变流器接通和断开相位的最佳组合。

Analysis and suppression of operational overvoltage and inrush current for high-speed trains by automatic phase-switching technique

Analysis and suppression of operational overvoltage and inrush current for high-speed trains by automatic phase-switching technique

When a high-speed train approaches the insulated phase-splitting section embedded between neighbouring power supply arms, the vacuum circuit breaker (VCB) installed on trains must be disconnected to maintain the traction power supply system as a no-load condition for completing phase-switching action, as the train passes through the phase-splitting section depending on its inertia. However, when operating VCBs, the arc is easily triggered between the mobile contacts inside, accompanied by an overvoltage impulse. Herein, to explore the generating mechanism of inrush current and operational overvoltage, a model describing the ‘substation-catenary-train’ traction power supply system is launched based on an equivalent circuit modelling technique. Through the analysis of the transient VCB operational process, the phase of catenary voltage is directly related to the characteristics of the VCB switching-on overvoltage, as the traction current's phase angle is relevant to the amplitude-frequency characteristics of the VCB switching-off overvoltage. Inrush current as a noteworthy element is related to the traction transformer's remanence. The automatic phase-switching technique is utilised to suppress both operational overvoltage and inrush current, as the optimal combination of VCB switching-on and switching-off phases considering the balance between overvoltage and inrush current is achieved based on the particle swarm algorithm.
