MAIN CIRCUIT TOPOLOGY STRUCTURE OF HYBRID LOCOMOTIVE WITH CONSTANT SPEED GENERATOR SET, AND POWER SUPPLY METHOD
Document Type and Number:
WIPO Patent Application WO/2022/002114
Kind Code:
A1
Abstract:
Disclosed in the present invention are a main circuit topology structure of a hybrid locomotive with a constant speed generator set, and a power supply method, which belong to the technical field of new energy shunting locomotives. The main circuit topology structure comprises a load, and further comprises a power battery pack, a diesel generator set and a ground power source. The load comprises an auxiliary system, a traction motor and a storage battery, the power battery pack is connected to an intermediate direct current loop, the intermediate direct current loop comprises a pre-charging circuit, a traction converter and a storage battery charger, and the other end of the pre-charging circuit is connected to the traction converter and the storage battery charger, and the traction converter and the storage battery charger are respectively connected to the traction motor and the storage battery. The main circuit topology structure further comprises a four-quadrant rectification module, one end of the four-quadrant rectification module being connected to the intermediate direct current loop, and the other end thereof being connected to the diesel generator set, the ground power source and the auxiliary system, so as to achieve the purpose of satisfying the requirements of hybrid control of locomotive power batteries and the diesel generator set.
