Propagation of nonlinear pulses in long lines with dispersion in the presence of low frequency current and voltage fluctuations

Abstract

The propagation of pulses of waves of current and voltage in long lines with nonlinearity and dispersion in the presence of low-frequency fluctuations of current and voltage, which can be caused by the influence of external EM fields generated by nearby electrical equipment of the industrial or energy object, is analytically investigated. It is shown that even neglecting losses, under the influence of low-frequency fluctuations external to the pulse, it is deformed, and, with propagation, the characteristic size of the pulse along the line and its amplitude changes.
