TRANSIENTS OF SYSTEM OF VOLTAGE SOURCE INVERTER INDUCTION MACHINE OF THE MINE LOCOMOTIVE WHEN POWERED FROM REAL SYSTEM OF POWER SUPPLY

Abstract

There have been developed a structural scheme of the electromechanical system of electric locomotive bogie model К14 in Matlab, which takes into account the elastic connection with gaps of locomotive engine to gearbox and from the gear to both wheels. Drive system voltage source inverter induction machine gets power from a source of infinite power through concentrated inductance and active resistance of the contact network, taking into account the accumulation of energy in capacitive filter of inverter. The proposed model allows to examine the effects of different laws control voltage source inverter induction machine on the dynamics of the system and to ensure the most rational character of transient processes starting-stopping electric locomotive.
