Annotation: A comparative evaluation of methods for describing the transient characteristics of an open power supply system (PSS) for a deep-water vehicle is proposed to solve the problem of approximating its complex mathematical model by transfer functions. Graphic and numerical methods for calculating the parameters of the transfer functions are considered, for which the accuracy of the approximation of the nonlinear PSS model is estimated. The conducted research allowed us to choose the method of approximation of the experimental characteristic of the output voltage of a real power supply system.

Keywords: power supply system, power transmission by cable-cable, transfer function, algorithm for calculating the parameters of the transfer function
