Dataware of Simulating Equipment Composition Influence on Electric Energy Quality of Railway Transport Enterprises

With due regard for external network influence the composition of installed electrical equipment determines harmonic composition of voltage in the supply unit. While changing the composition of electric equipment one should expect the quality change of electric energy (EQ) in the supply unit, non-sinusoidal parameters of the duty included. It is connected with the fact that each type of electric receiver (ER) influences the harmonic current and voltage composition to a variable degree. It follows from the experience that even at the same load voltage the change of equipment composition brings to changing harmonic spectre of consumed currents and voltages in the units in question.
