METHOD AND DEVICE FOR TRANSMISSION OF POWER Russian patent published in 2012 - IPC H02J17/00 

FIELD: electricity.

SUBSTANCE: in a method to transmit power along an overhead radial power transmission line from a step-down substation to loads distributed along a radial line at the frequency of 50-60 Hz the power is sent additionally to an end load of the radial line from the step-down substation via a rectifier, a frequency converter and a resonant circuit along a single-wire line at a resonant frequency of 0.4-100 kHz to a resonant circuit, a rectifier and a network inverter, the network inverter 50-60 Hz is attached at the end load to the radial overhead line, and then power is sent from the end load along an overhead radial line to other distributed loads connected to the radial line. Power to the end load of the radial line is sent along a single-wire cable line or a single-wire line by its placement on supports of the overhead radial line. The device to transfer power comprises at the substation a rectifier, a frequency converter and a resonant circuit, the medium outlet of which is connected to a single-wire line, the single-wire line is connected at the end load with the end of the radial line via a resonant circuit, a rectifier and a network inverter.

EFFECT: higher reliability of power supply, reduced losses in a power transmission line and increased power transmitted in lines.
