Determination of optimal values of controlled variable transformers.
Analytical expressions are obtained for determining the optimal values of the main controlled variables during unconditional optimization of a power transformer. The optimal value of the diameter of the rod and the induction in it are obtained on the basis of the criterion of national economic expenditures and the generalized mathematical model, which takes into account the various design versions of the magnetic core and windings. The optimal values of current density and dimensions of the winding conductors are determined using a particular criterion of the cost of the winding, which is obtained taking into account the quasi-separability of the criterion - the national economic costs relative to the controlled variable windings.
