Owing to increase of a current consumption, the electric system is appeared on
the verge of excess for rated loading. At the same time, tendencies of last decade have
shown that the problem of full-scale modernization of power branch is open and the
network companies are forced to work with the equipment which has almost
exhausted the resource. Taking into account it, the economy of electropower branch
starts to prefer sources of the distributed generation [1'3] which are integrated into
distribution network. Now there is no possibility of exact definition of the electric
power losses in conditionally closed circuits, because energy overflows between
mutual spare circuits both in normal and in emergency conditions are not taken into
account. Therefore, circuits’ state optimization of the distributive electric system
becomes a problem question. Its solution will allow using available power capacities
more effectively.
