Method for controlling dual power engineering maintenance vehicle to pass area without electricity

Abstract

The invention discloses a method for controlling a dual power engineering maintenance vehicle to pass an area without electricity. The characteristic of two current collecting modes of the dual power engineering maintenance vehicle is fully utilized, and in the process of passing the areas without electricity, the restriction of conditions such as the speed of the dual power engineering maintenance vehicle entering the area without electricity, a slope, a distances of the area without electricity and the like is not required to be considered, and if the dual power engineering maintenance vehicle does not pass the area without electricity from an undervoltage value to a no-voltage value, the dual power engineering maintenance vehicle is switched from a third-rail current collecting mode to a traction battery current collecting mode. By the method, the manual operation of a driver is reduced, and the dual power engineering maintenance vehicle passes the area without electricity safely and reliably.

Description

technical field [0001] The invention relates to a control method for a dual power supply engineering maintenance vehicle passing through a non-electric zone. Background technique [0002] The currently used electric locomotives pass through the non-electric area, which is called over-phase, and there are three control methods: automatic over-phase, semi-automatic over-phase, and automatic over-phase. The control method of the electric zone. Since the two current receiving methods of the dual-power engineering vehicle are DC voltages, which are different from the voltages at both ends of the phase-splitting area of ​​the electric locomotive, the existing control methods have the following problems: [0003] 1) The driver needs to consider whether the speed of the vehicle can pass through the no-power zone, the slope of the no-power zone, etc. before passing through the no-power zone; [0004] 2) Before reaching the non-electric zone, the driver needs to stop and manually ch...

Problems solved by technology

[0004] 2) Before reaching the non-electric area, the driver needs to stop and manually change the current receiving mode of the third rail to the current receiving mode of the traction battery, which reduces the efficiency of locomotive operation and increases the complexity of the driver's manual operation
