Abstract

The invention discloses an electrical control method for a hybrid power rail car. The electrical control method comprises a generator power supply mode, a power battery power supply mode and a hybrid power supply mode. In the hybrid power supply mode, the engine drives the generator to generate three-phase alternating current, and the three-phase alternating current is controllably rectified by the rectifier module to supply power to the intermediate direct current link. A power battery supplies power to the intermediate direct current link after being boosted by the chopping reactor, the first bridge arm and the supporting capacitor in sequence. After the electric energy output by the generator and the electric energy output by the power battery realize parallel power supply in the intermediate direct current link, one path supplies power to the traction motor through the traction inversion module, and the other path supplies power to the auxiliary load through the auxiliary inversion module. The technical problems that an existing electrical system adopts uncontrollable rectification, the size of intermediate direct-current voltage cannot be adjusted, a contact network and an engine unit cannot supply power at the same time, and power is insufficient due to the fact that the system cannot adapt to power reduction operation of an engine in a contact network-free environment and a plateau environment can be solved.

Description

technical field [0001] The invention relates to the technical field of track engineering electrical technology, in particular to an electrical control method for a "internal combustion + power battery" hybrid rail vehicle. Background technique [0002] At present, my country's high-speed railway has been fully promoted, and a large number of long tunnels have been newly built. However, a large number of existing railway railcars are powered by internal combustion engines. During tunnel construction, the exhaust gas emitted by diesel engines is not easy to spread in a short time, which makes the work site visibility and The air quality is poor, which seriously affects the safety, health and work efficiency of construction personnel, and there are great potential safety hazards. The existing internal combustion rail car electrical system mainly has the following deficiencies: [0003] 1) The power system of the traditional internal combustion rail car adopts the hydraulic (hyd...
