| Summary: | The article offers a method for identifying parameters
of mathematical models of electrical complexes and
systems. The method is designed to create a system for
monitoring the influence of nonlinear components of
electrical complexes and systems in their deep interaction
on the quality of electrical energy in the load node. The
application of the coefficient of variation of parameters as
a criterion for evaluating the reliability of identification
of parameters of mathematical models is justified. As
the initial information, digitized data of the voltage at
the point of common connection and the currents of
individual components of the analyzed complex are used.
The mathematical apparatus of identification is based
on a modification of the Marquardt method. A series of
computational experiments confirms the main theoretical
provisions of the article. It is shown that it is possible to
identify the parameters of models of complex components
with a significantly nonlinear form of stress at the point of
common connection. |
