| Abstract |
This work is focused on the improving of the energy efficiency of electrical train in braking mode. The improvement is explored by integration and control of a reversible inverter in a DC power substation to inject the braking power from the DC railway electrical network to the AC transmission grid. This solution makes the power substation reversible. The objective of this study is to investigate a control strategy by adjustment of the catenary DC voltage by the inverter in order to recover the maximum of electric braking energy by keeping the DC voltage of the substation stable with a reference value. A comparative study of simulation results of the proposed control scheme with a droop control technique for the railway substation "Massena" in Paris is presented. |
