To solve the negative sequence (NS) problem and enhance the regenerative braking energy (RBE) utilisation in an electrified railway, a novel energy storage traction power supply system (ESTPSS) is proposed in this study.
Accordingly, a flexible traction power supply system (FTPSS) composed of a TT and multi-port power hub and its coordinated control strategy are proposed for VU compensation and energy conservation in this paper. The main contributions can be summarized as follows:
Shu et al. proposed a further advanced solution known as the “co-phase traction power supply system”, which achieved full compensation of negative sequence (NS) current and eliminate neutral sections.
To mitigate voltage unbalance (VU) and eliminate the neutral sections while reducing the energy consumption of railways, a flexible traction power supply system (FTPSS) with the power hub is proposed.
The AC/DC converter 1, AC/DC converter 2, and AC/DC converter 3 exchange power between the utility grid and the power hub through the Y/D connecting transformer. The AC/DC converter 4 is connected to the TMT to transfer the energy between the power hub and the traction network.
Through the coordinated control strategy of FTPSS, the effect of peak clipping and valley filling of traction load is obvious, as illustrated in Fig. 12 (b) and Fig. 12 (c). The exchanging power between TPSS and the grid is greatly reduced, and the maximum demand power is reduced from 12.2 MW to 7.8 MW compared with conventional TPSS.
