METHOD AND DEVICE FOR TRANSMISSION OF ELECTRICAL ENERGY Russian patent published in 2021 - IPC H02J13/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. The method includes converting electrical energy of an energy source by frequency in a transmitting frequency converter and by voltage in a transmitting Tesla transformer, transmitting electrical energy at high frequency along a high-voltage single-wire line to a Tesla receiving transformer, converting electrical energy by voltage in a Tesla receiving transformer and by frequency in a receiving inverter and transmission of electrical energy to the consumer. According to the invention, the transmission of electrical energy is carried out from n remote from each other power sources controlled from the control room at a resonant frequency of fl - 500 kHz and a voltage of 1–1000 kV along n single-wire lines, where n=1, 2, 3..., to one distributed consumer. Controlled electrical energy sources convert energy from renewable energy sources and energy from fossil fuels into electrical energy. The distributed consumer is performed in the form of a three-phase line or microgrid, along which Tesla receiving transformers and inverters controlled from the dispatch center are installed at a distance from each other. Each frequency converter performs the function of control and regulation of frequency, voltage and transmitted power, and each inverter - functions of regulation of maintaining the symmetry of voltage and transmitted power in the phases of a three-phase line. The total length of each single-wire line is related to the resonant frequency by the ratio: fl = nC/2l, where fl is the resonant frequency of oscillations; l - line length; C is the speed of light.

EFFECT: reducing the influence of the frequency of energy sources using renewable energy on the frequency and modes of operation of a distributed energy consumer in the form of a backbone line or microgrid.
