** Description:** A mathematical vehicle is offered for drafting of the programs of calculation on computer as evaluated by the regulation effect of compensating devices (CD) during the translation of unregulated compensating devices in managed with providing of a minimum of losses of active power in a grid, and also it is shown as on the offered mathematical vehicle the proper programs can be made for conducting of calculations on computer. The calculation of the set mode is based on the decision of the system of equalizations of the set mode of balancing knot, for supporting and unsupporting knots at certain initial conditions. In addition, the places of setting of managed compensating devices are beforehand predefined existent substations with unregulated compensating devices, that limits an application of the offered method the task of modernization of existent electric network domain.
