The article is devoted to solving one of the major
problems in electric power industry, which is to
simplify and improve the accuracy of simulation and
calculation modes of complex electrical systems with
using the frequency characteristics of the elements of
the power system in generalized vector space. Article
has an exploratory character, which is expressed that
mathematical models of static elements of an electrical
network are considered in the form of transfer functions
of dependence of conduction on the frequency. A
number of the provisions of article has scientific
originality which is in the approach to the choice of the
coordinate system for modeling static elements. It is
offered the mathematical models air and cable
transmission lines, generalized load, single reactors
generalized vector space for analysis of steady and
transient modes. As an example was calculated family
of real and imaginary parts of the frequency
characteristics of the AC-70 line with different values
of the length, lines with different section (AC-70, AC-
95, AC-120), generalized load with different ratios of active and reactive power, various types of single
reactors. Offered mathematical models allow exploring
different symmetric modes of electric networks using
more efficient mathematical apparatus
In this article, the software that allows to determine the ranges of deviations of a motor anchor chain current and angular velocity deviations of a DC elec-tric drive with a thyristor converter in the continuous currents mode has been presented
