The method according to the invention aims to optimize the operation of a reversible traction substation (Sk) of a power supply system () for railway vehicles, said reversible substation being able to be commanded in a traction operating mode or a braking mode. This method includes:

Method for optimizing the operation of a reversible traction substation and associated devices

A method of monitoring and regulating the power and the energy consumed by a transport system including electrically propelled vehicles, said transport system including a power supply system including one or more power supply substations connected to an external electrical power supply network, said power supply substation or substations supplying energy to traction substations supplying power to power supply line sections having vehicle-mounted current pick-up means connected thereto, each vehicle carrying a power converter which is supplied with power by said current pick-up means and which monitors the power supplied to a traction motor of said vehicle, which method includes the following steps:

Method and a system for monitoring and regulating the power consumed by a transport system

A system for supplying current through the ground for an electric vehicle, especially for an electric rail vehicle, includes a succession of conducting segments ( A, B, C, D) which are electrically isolated from each other and together form a conducting supply track against which at least one supply collector shoe ( ) on the vehicle is applied, and a set of high-voltage supply devices ( ) each connected to a conducting segment and each provided with a detector capable of detecting a collector shoe and with switching devices ( ) 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 ( ) when a collector shoe is not present thereon. The switching devices include a pair of elements (T , T ) forming static switches controlled by detector ( ) in order to cause the corresponding segment to be supplied with current when a collector shoe is present thereon and to be connected to the zero-potential source when a collector shoe is not present thereon, respectively. Each supply device furthermore includes short-circuiting devices ( ) which are forced into the closed state, and are interposed between the corresponding segment and the zero-potential source ( ), and which are made to open by the detector ( ).

Static system for supplying current through the ground for an electric vehicle and electric vehicle intended to be supplied by means of such a supply system

A buried power supply system for an electric vehicle (,) equipped with collector shoes (,), the system comprising a succession of conductive segments (,A,,B,,C) 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 (,) of the static type, which means are received under the segment in a trough along which a common power supply link (,) and a common return link (,) 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 (,C) or by either of the immediately adjacent segments (,B,,D). The vehicles include means for transmitting a connection control signal to a segment of track.
