Abstract: The method according to the invention aims to optimize the operation of a reversible traction substation (Sk) of a power supply system (4) for railway vehicles, said reversible substation being able to be commanded in a traction operating mode or a braking mode. This method includes: determining a current value (Mc) of a favored operating mode; maximizing at least one optimization function (F) that depends on the current value of the favored operating mode, based on instantaneous values (G(t)) of multiple operating properties of the substation (Sk); computing optimized values (Popt(t)) for multiple configuration parameters of the substation (Sk) from maximized values (Gmax(t)) of the operating properties.

Abstract: A system for supplying current through the ground for an electric vehicle, especially for an electric rail vehicle, includes a succession of conducting segments (16A, 16B, 16C, 16D) which are electrically isolated from each other and together form a conducting supply track against which at least one supply collector shoe (32) on the vehicle is applied, and a set of high-voltage supply devices (20) each connected to a conducting segment and each provided with a detector capable of detecting a collector shoe and with switching devices (45) suitable for selectively causing a corresponding segment to be supplied with current when a collector shoe is present on the segment and causing the said collector shoe to be connected to a zero-potential source (26) when a collector shoe is not present thereon.

Abstract: A buried power supply system for an electric vehicle (17) equipped with collector shoes (16, 22), the system comprising a succession of conductive segments (5A, 5B, 5C) that are electrically isolated from one another, and that form a conductive track for the shoes on a road surface. Each segment is provided with individual switching means (11) of the static type, which means are received under the segment in a trough along which a common power supply link (14) and a common return link (13) run. The switching means provide electrical continuity between the segment to which they are assigned and the power return link so long as a connection control signal for connecting a segment to the power supply link is not received from a vehicle either directly by the segment in question (5C) or by either of the immediately adjacent segments (5B, 5D). The vehicles include means for transmitting a connection control signal to a segment of track.
