An apparatus in which electric power is generated for an electrical load from differentials in electric field strengths within a vicinity of powerlines includes: a plurality of electrodes separated and electrically insulated from one another for enabling differentials in voltage resulting from differentials in electric field strength experienced there at; and electrical components electrically connected therewith and configurable to establish one or more electric circuits whereby voltage differentials cause a current to flow through the established electric circuit for powering the electrical load. Preferably, the apparatus includes a control assembly having one or more voltage-detector components configured to detect relative voltages of the electrodes; and a processor enabled to configure-based on the detected voltages and based on voltage and electric current specifications for powering the electrical load—one or more of the electrical components to establish an electric circuit for powering the electrical load.

A power supply and control system for electrically powered shuttle-trains incorporates at least one shuttle train having a motor and a generator. A first plurality of track segments has associated synchronous power modules exchanging power synchronously with a power grid through a plurality of power supply rail segments connectable to the motor or generator. A second plurality of track segments has associated variable frequency power modules exchanging power through a second plurality of power supply rail segments connectable to the motor or generator. Isolation segments separate adjacent power supply rail segments. A control system interconnected to the variable frequency power modules controls the frequency of each variable frequency power module based on the location of the shuttle train.

A control assembly includes a monitoring module and a switching module. The monitoring module determines a load demand of a first rail vehicle traveling along a track, wherein the first rail vehicle is supplied with electric current from a plurality of power sources over a conductive pathway extending along the track. The switching module is communicatively coupled with the monitoring module and is joined with a switch controller disposed between the power sources and the conductive pathway. The switching module directs the switch controller to change which of the power sources supply the electric current to the first rail vehicle over the conductive pathway based on the load demand.

This method for deicing a direct current power supply line for railway vehicles is provided for a line extending between at least a first and a second reversible substations able to supply an electrical current circulating on the electrical power supply line, the first substation being controlled in a current supply mode, to supply an electrical current to the electrical power supply line and the second substation being controlled in a current recovery mode, to recover the electrical current from the electrical power supply line and send it back on an electrical power supply network. The method comprises establishing a voltage difference between the output terminals of the first and second substations such that a current circulates on the electrical power supply line between the two substations and that the heat produced by the circulation of the current causes the deicing of the power supply line between the two substations.

A device for switching stator sections that are arranged on both sides of a guideway, for instance of a magnetic levitation railway system. In order for the device to be installed in as independent a manner as possible, the separately installed switching stations comprise not more than three switchboard sections each and are associated with only one stator section. The switching sections are therefore more compact and less heavy.

A trackside power distribution apparatus includes overlapping feeders. A first signal supply unit has an input adapted to receive power from a first electrical power source and an output for supply of power to a feeder. A first portion of feeder is connected to the output of the first signal supply unit and extends alongside a track to a unit requiring power. A second signal supply unit has an input adapted to receive power from a second electrical power source and an output for supply of power to a feeder. A second portion of feeder is connected to the output of the second signal supply unit and extends alongside the track to the unit requiring power. A selection apparatus is also provided which selects which feeder portion is used to supply power to the unit. The provision of the two feeder portions improves the reliability of the apparatus in the event that one power source fails.
