Dynamic Modelling of Braking Energy Recovered Using a Bi-Directional Power Station on DC Railway Electrical Network

This paper deals with a specific electrical railway section involving two classical power stations: Quai de la Gare and Les Ardoines. These two power stations surround Massena, a power station that has been made reversible by adding an IGBT inverter. The study is focussed on the dynamic modelling of both DC and AC parts of the aforementioned power stations in order to highlight the new energy flows that occur in this innovative configuration. The objective of this paper is to quantify the amount of energy recovered during braking phases with the new inverter. The studied case that implements a very basic traffic simulation shows that the train electrical braking power rises and the amount of energy recovered in twelve minutes can be valued to 7kwh.
