【 摘 要 】

The electrical stations (substations) represents the basic subsystems of electric power system and is necessary the modes of operation evaluation and modeling of these with a view to establish, later on, a degree of continuity in electric energy supply of load points or customers connected at these electrical stations or substations. Adoption the optimal solutions of supply with electrical energy of industrial consumers is a very complex problem which involve analyses one of very large number of restrictions and factors, with determinist character quasi-determinate and aleatory. In this paper is presented a method for determinate the optimal apparent power of electric transformers, respective the optimal demand coefficient in the first year of exploitation using the economic criteria and the Matlab -Simulink program.
