Abstract

The aim of the present work is to find a computational model, sufficiently simplified for practical use which determines the sensitivity of the complex high-voltage electrical networks when switching compensatory powers. We show how this model can be used as a basis for creating practical criteria for a one-valued choice in the two situations. First, switching the compensatory power does not lead to leaving the permissible range of voltage. In this case the power which minimizes the power losses is used. Second, the compensatory power is switched in order to return the voltage to the permissible range. Then that compensatory medium is chosen which is sensitive enough in addition to causing the minimal increase in electrical power losses.
