FIELD: electricity.
SUBSTANCE: device proposes a new method for rational macromodelling of multiterminal networks, which ensures high accuracy under arbitrary border conditions. This is achieved by means of reformulation of a method of vector approximation to approximate internal pairs, and not the matrix elements, at the same time the weight ratio is selected as equal to a reverse value of its own value, in order to produce a criterion of relative accuracy to select its own value. The method provides a significant improvement of accuracy for cases with significant dispersion of own values. It is also demonstrated how to use impedance characteristics of an attached network to reduce complexity of approximation and additional improvement of its accuracy.
EFFECT: accuracy improvement.
