Abstract

The invention provides a distributed railway regenerative electric energy cloud control system. Regenerative electric energy utilization equipment is simultaneously arranged in a plurality of traction substations and a plurality of subareas along a railway, all adjacent 27.5 kV traction power supply arms are communicated, and a plurality of mutually isolated traction power supply arms are equivalent to the same single traction power supply arm. On edge cloud equipment and center cloud equipment, an algorithm strategy applying for and obtaining a national patent is deployed, regenerative electric energy is intelligently scheduled, and the absorption and utilization range of the regenerative electric energy is expanded. Meanwhile, an energy storage unit is adopted to balance the time difference between the generation and the absorption and utilization of the regenerative electric energy; and the maximum demand values of the transformers of the traction substations are effectively reduced by fully utilizing the regenerative electric energy. A global intelligent cloud control technology is adopted, the utilization rate of regenerative electric energy is improved, and comprehensive energy conservation of a railway traction power supply system is achieved.

Description

technical field [0001] The invention belongs to the technical field of electrification control, and relates to a distributed railway regenerative electric energy cloud control system. Background technique [0002] The traction power of the electrified railway mainly adopts AC transmission locomotives in freight transportation, and AC transmission locomotives or EMUs in passenger transportation. However, AC drive locomotives or EMUs mainly use regenerative braking, which will generate a large amount of regenerative braking electric energy in the traction catenary. [0003] At present, there are mainly two methods of utilizing regenerative electric energy that can bring benefits to railway units: one does not require additional equipment, and the regenerative electric energy is directly used by traction locomotives under the power supply arm of the same parallel connection, but the circuit is uncontrollable random Utilization; the other is to increase the conversion and energ...
