MULTIPHASE VOLTAGE TRANSMISSION DEVICE FOR SINGLE LINE Russian patent published in 2017 - IPC H02M5/27 

FIELD: electricity.

SUBSTANCE: in the proposed invention, a single-wire line is used for transmission (a common ground bus is used instead of the C₀-C_0wire). The invention has improved energy performance as a result of the introduction of repetition blocks and pulse delay into each phase. In the proposed solution, the "empty" time intervals between adjacent single voltage pulses are filled with repetitive voltage pulses that repeat a single pulse, the number of such repetitive pulses in the time interval T can range from 1 to (n-1). Complete filling of empty time intervals will be at the number of pulses equal to (n-1). In this case, the voltage waveform on the load will be stepped, not containing empty (not filled with voltage pulses) time intervals. The envelope of the voltage step function on the load will approach the sinusoidal form. The smaller the time interval T, the more accurately the envelope will approach the sinusoidal form. As a result, the effective voltage, active, reactive and apparent power on U', P', Q', S' loads, will be closer to the values of U, P, Q, S, which are specific for the transmission of the multi-phase voltage system along multiphase transmission line. Filling of empty intervals by voltage pulses in the device is carried out by means of repetition blocks and pulses delay.

EFFECT: enlarging functional capabilities of a multiphase voltage system transmission.
