Description
Summary:The paper presents similarity theory used for of complex systems for physical modeling mode of operation of variable frequency drives as generators of higher harmonics of currents and voltages in the system of power supply of the enterprise. The π-criteria of similarity are compiled and scaling factors for a low-power variable frequency electric drive that is in located specific accordance with an industrial variable frequency electric drives of various power. The received criteria and scale factors allowed to estimate electromagnetic compatibility in power supply systems by the example of a factory for the manufacture of reinforced concrete products. The article was prepared within a development program of the Base University on the basis of BSTU named after V.G. Shukhov.
