轨旁储能系统的引入对于直流电气化铁路再生制动能量的回收是有效的。然而，考虑到它们的部署成本，优选的是以能量存储装置（ESD）的最小容量来最大化节能效果。在本文中，我们提出了一种功率控制方法，可以提高节能效果，同时管理能源的ESD。所提出的方法通过根据ESD的能量和它们所连接的架空接触线的线电压来控制ESD的功率转换器的线路侧的滤波电容器电压来实现。接下来，所提出的方法进行了验证，数值模拟和实验测试与1千瓦级缩小模型。
The introduction of wayside energy storage systems is effective for the recovery of regenerative brake energy in dc‐electrified railways. However, considering the cost of their deployment, it is preferable to maximize the energy saving effect with a minimum capacity of the energy storage devices (ESDs). In this paper, we propose a power control method that can improve the energy saving effect while managing the energy of the ESDs. The proposed method is implemented by controlling the filter capacitor voltage of the line side of the power converter for the ESDs depending on their energy and the line voltage of the overhead contact line to which they are connected. Next, the proposed method is verified by numerical simulations and experimental tests with a 1 kW class downsized model.
