“…However, if there are no traction locomotives or there are also braking locomotives in the adjacent power supply sections, RBE cannot be effectively utilized. To solve this limitation, a PTD with the ESS (EPTD) is proposed to store surplus RBE (such as an RPC with an ESS [32,33] or an RPC with a super capacitor [34]). However, the RBE generated by high-speed and heavy-haul trains is considerable, leading to high capacity and high cost of EES.…”

This paper proposes a centralized-decentralized control strategy for regenerative braking energy utilization and power quality improvement in the modified AC-fed railway system with energy-storage-based smart electrical infrastructure. The proposal of a centralized-decentralized control strategy can enhance the ability to withstand and rapidly recover from disruptions, thus providing further guarantees for safe and reliable operation and energy conservation for railway systems. First of all, the description and control strategy of the modified railway system are outlined, and then the control principles and implementation process of the centralized control and decentralized control strategies are given. Moreover, a method of load power detection and regulated power reference calculation is proposed. Finally, the effectiveness of the proposed strategy is verified in a case of a modified railway system consisting of four traction substations and eight power supply sections. The results demonstrate that regenerative braking energy can be efficiently utilized in railways and that power quality can be improved using the proposed centralized-decentralized control strategy.

“…For instance, a comprehensive analysis of the FB-RPC system based on an unbalanced open-delta (V/V) power transformer, providing simulation and experimental results, is presented in [6]. An RPC system, based on V/V power transformer and equipped with an energy storage system, is presented in [11], which uses a supercapacitor that is connected to the DC-link of the RPC via a bidirectional DC-DC converter. This energy storage system is useful for reducing the peak power demand and the operation costs in a railway substation.…”

Electric locomotives in AC traction power systems represent a huge single-phase non-linear load and, detrimentally, affect the power quality and the efficiency of the three-phase power grid. Nevertheless, along the last decades, power electronics are being used to mitigate power quality problems in the three-phase power grid. In particular, Rail Power Conditioner (RPC) helps to increase the loading capacity of traction substations and improve the power quality of three-phase power grids. As the main characteristics, an RPC can supply reactive power, suppress current harmonics and overcome currents imbalance of the three-phase power grid. On the other hand, the traction substations may be constituted by different types of power transformers. For instance, single-phase power transformers and open-delta (V/V) power transformers are widely used, while Scott power transformers are less frequently used, since they are more complex and expensive. In this framework, this work presents a review study of RPC topologies, including their operation modes, and a comprehensive comparison between the characteristics of the RPC topologies when using different types of AC traction substations and power transformers. This helps to ensure the correct selection of the RPC topology for a specific application, according to the main structure of the traction substation. Consequently, and based on the established review, it is possible to sort and allocate each RPC topology for limited or wider applications.
