Применение принципа обратной связи для решения уравнений трансформаторов и электрических машин

Abstract

Anapproach is suggested according to which the primary winding resistance istakeninto account using the well-known feed back principle. The search procedure involves two stages. In the first stage, a voltage source is applied behind the resistance. Then, if flux linkages of the loops are taken as independent variables instead of currents, the order of the equation system to be solved is decreased by unity, a circumstance due to which both the search and the form of sought solutions become essentially simpler. Atthesecondstage, a mathematically rigorous correlation between the conditional and actual voltage across the terminals is found using atechnique known as the feed back principle, as a result of which the preliminarily found quantities are presented as functions of the actual voltage across the terminals. Examples demonstrating the validity and effectiveness of the proposed approach are given as applied to a number of problems concerned with studying steady-state and transient modes of electrical machines and transformers.
