METHOD OF HYBRID LOCOMOTIVE POWER PLANT CONTROL

摘要

FIELD: transport.SUBSTANCE: invention relates to railway transport, particularly, to control over locomotive power plants. Proposed method consists in varying load at ICE at changing ICE shaft angular speed. Said load is decreased by reducing load at generator. Traction power is increased by adjusting current and voltage inverter and controller. Adjustment is carried out to allow discharging power accumulator in power circuit unless accumulated power reaches preset minimum magnitude. Transition process is controlled to allow charging said power accumulator. Said power accumulator is charged by stepwise increase in ICE shaft angular speed and exploiting traction generator free power. During said transient process, control system sets admissible minimum excess air factor.EFFECT: higher efficiency.4 dwg
