Problems solved by technology

[0002] According to different power supply systems, subway engineering vehicles can be divided into electric locomotives powered by the grid and electric drive diesel locomotives powered by on-board internal combustion engines. However, there is currently no dual-energy subway engineering vehicle that combines the above two power supply systems, so that When a power supply fails, start another power supply to work in time, thereby reducing the operational risk of the locomotive

Embodiment 1

[0050] Based on Embodiment 1, Embodiment 2 of the present invention discloses a dual-energy locomotive control system, including: a driver controller, a traction motor, a traction inverter connected to the power grid and the traction motor, an internal combustion generator set, and a The generator set and the rectifier of the traction inverter, and any dual-energy locomotive controller described in Embodiment 1;

[0051] Wherein, the internal combustion engine can adopt a diesel engine;

[0052] Wherein, the internal combustion generator set may include a low-power internal combustion generator set, that is, the internal combustion engine includes a low-power internal combustion engine, and the generator includes a low-power generator;

[0053] Since the existing electric drive diesel locomotives all use a dedicated high-power internal combustion generator set as the only power supply; then for the dual-energy subway engineering vehicles of the smaller power series, it is nece...

Embodiment 2

[0056] Based on the second embodiment, the third embodiment of the present invention also discloses a dual-energy subway engineering vehicle, including: any dual-energy locomotive control system described in the second embodiment.

[0057] In summary, the present invention adjusts the output power of the traction inverter through the traction characteristic control module to make it meet the output power given by the driver controller, thereby realizing the traction level control of the locomotive and establishing the traction level of the locomotive control system; under the grid power supply system, the traction level control system of the locomotive can be directly powered by the DC power grid to drive the locomotive to run stably; while under the vehicle-mounted internal combustion engine power supply system, due to the change of the output power of the traction inverter, The output power of the internal combustion generator set will inevitably change accordingly (specifica...

Abstract

The embodiment of the invention discloses a dual-energy locomotive controller, a control system and a subway engineering vehicle. The controller is applied to the system, and the system includes a driver controller, a traction motor, a traction inverter connected to the power grid and the traction motor, An internal combustion generator set (including an internal combustion engine and a generator) and a rectifier connected to an internal combustion generator set and a traction inverter, the dual-energy locomotive controller includes: the traction characteristics of the input end connected with the driver controller, and the output end connected with the traction inverter a control module; a measurement module connected to the internal combustion generator set, used to measure the speed of the internal combustion engine and the output voltage of the generator; and a unit control module respectively connected to the measurement module and the internal combustion generator set, used to measure the speed and The output voltage adopts a negative feedback control method to adjust the speed of the internal combustion engine to a preset speed value, and adjust the voltage of the generator to a preset voltage value, so as to realize the on-rail operation of the dual-energy subway engineering vehicle.

Description

technical field [0001] The invention relates to the technical field of mechatronics, and more specifically relates to a dual-energy locomotive controller, a dual-energy locomotive control system and a dual-energy subway engineering vehicle. Background technique [0002] According to different power supply systems, subway engineering vehicles can be divided into electric locomotives powered by the grid and electric drive internal combustion locomotives powered by on-board internal combustion engines. However, there is currently no dual-energy subway engineering vehicle that combines the above two power supply systems, so that When a power supply fails, start another power supply in time to work, thereby reducing the operation risk of the locomotive. [0003] Therefore, how to realize the on-rail operation of the dual-energy subway engineering vehicle has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, t...
