The relevance of the study is caused by the necessity to enlarge transfer capacity of the main ultrahigh voltage power transmission under static stability terms. The aim of the study: to substantiate and to develop the procedure for selecting the compensating device parameters of controlled ultrahigh voltage power transmissions with the intermediate systems to increase the transfer capacity under static stability terms. The methods of the study is The intermediate energy systems connected to the distant ultrahigh voltage transmission are represented by their voltage generalized static characteristics of reactive power. The power system condition is described by the steady state equations which are complemented by practical criteria of static stability. Results: the analytic solution of the problem for selecting the options of the compensating devices of distant electric power with two intermediate systems were obtained; the numerical examples were shown and illustrated.
