Optimization Design of Automatic Neutral-section Passing Control for High-power AC Freight Electric Locomotive
In this paper, the locomotive automatic neutral-section control logic optimization was researched to tackle the problem of insufficient traction/braking force in some neutral-section and false signal from neutral-section device of HXD1 high-power electric locomotive. Then a new traction power reduct...

| description | In this paper, the locomotive automatic neutral-section control logic optimization was researched to tackle the problem of insufficient traction/braking force in some neutral-section and false signal from neutral-section device of HXD1 high-power electric locomotive. Then a new traction power reduction slope was proposed to solve the problem of insufficient power caused by reducing the power in advance after entering neutral-section, and a distance control method was adopted to solve the problem that the control system cannot give a command to close the main circuit breaker when receiving a wrong signal. The simulation and field test results show that the optimization program helps electric locomotive with heavy haul train successfully pass through the neutral-section under different road conditions and different device states. |
