Abstract
The questions of optimal selection of installed power of levels controllable compensating devices have been considered.Objective function of minimization expenditure has been reduced.In detail, an algorithm of selection's power and in depends on a diagram of consumption level's number of regulation plant of compensation reactive power has been determined.The algorithm has been tasted on data's of consumption of JSC «URICM» company. The diagrams of consumption active and reactive power have been analyzed. A diagram of distribution of value for compensation reactive capacity has been constructed.A choice of optimal correlation power and numbers of levels regulation has been made. The total table of the switching circuitry of steps of the compensating device which is a control algorithm chosen for electric supply system of the factory of JSC «URICM» of automatic installation of a reactive power compensation power of 1450 kvar is gained.
