Double-energy-source alternating current transmission locomotive control system and locomotive with system

Abstract

The invention discloses a double-energy-source alternating current transmission locomotive control system, which comprises an electric power control device, an internal combustion engine control device, a driver controller and a sensor, wherein the electric power control device and the internal combustion engine control device are both connected with an inverter control device; the driver controller is used for controlling either the internal combustion engine control device or the electric power control device to work; the sensor is used for detecting the rotating speed of a diesel engine or the voltage of a power generator; the sensor is connected with the internal combustion engine control device; when the rotating speed of the diesel engine and the voltage of the power generator both reach the set values, the internal combustion engine control device controls the inverter control device to regulate the output power. The electric power control device and the internal combustion engine control device are controlled through the same driver controller so as to realize the work of the locomotive in two modes including the internal combustion mode and the electric power mode; in the internal combustion engine power supply mode, the passive regulation of the powder in the prior art can be avoided, so that the machine unit speed regulation control and power control can be realized. The invention also provides a locomotive comprising the double-energy-source alternating current transmission locomotive control system.

Description

technical field [0001] The invention relates to the technical field of rail locomotives, and more specifically, relates to a dual-energy AC drive locomotive control system and a locomotive with the system. Background technique [0002] At present, in the domestic rail locomotive industry, there are few rail traction locomotives driven by the two energy sources of on-board internal combustion units and grid power. Under normal conditions, the vehicle-level control system still adopts the electric traction system under the catenary power supply mode, and the internal combustion unit adopts constant speed control, and the internal combustion unit control system is independent of the vehicle, that is, it is controlled separately. [0003] The advantage of this method is that the vehicle control system is relatively simple and easy to integrate. However, the disadvantages are: the internal combustion unit cannot adjust the speed and is always at the rated speed, which will cause...

AI Technical Summary

Problems solved by technology

However, the disadvantages are: the internal combustion unit cannot adjust the speed and is always at the rated speed, which will cause increased wear, increased fuel consumption, and increased noise when the unit is under no-load or light-load conditions, which has a significant impact on larger power diesel units; The group is not controlled according to the constant power, the power at the rated speed is not fully exerted, and the efficiency will be reduced; because in the power supply mode of the internal combustion unit, the vehicle-level control system does not include the control of the internal combustion unit, and the output power of the internal combustion unit is only "passively" to meet the load. Power demand, so the speed fluctuates greatly and the stability is poor

[0004] The above problems have many deficiencies for larger power diesel units and shunting locomotives that operate under idling conditions for a long time
