Abstract

The invention is applicable to the technical field of power grids, and provides a control method and device of a multi-energy coupling system and terminal equipment, and the method comprises the steps: obtaining an electric energy quality parameter of a new energy power generation system, a load parameter of a traction power supply system and a working parameter of a hybrid energy storage system;and according to the electric energy quality parameter of the new energy power generation system, the load parameter of the traction power supply system and the working parameter of the hybrid energystorage system, controlling the working states of a grid-connected inverter and a railway power adjusting device so as to enable the new energy power generation system, the traction power supply system and the hybrid energy storage system to realize energy intercommunication. Energy intercommunication among the new energy power generation system, the traction power supply system and the hybrid energy storage system can be achieved, the problems that the traction power supply system is poor in electric energy quality and regenerative braking energy is wasted can be solved, and the electric energy quality problem of new energy power generation can also be solved.

Description

technical field [0001] The invention belongs to the technical field of electrified railways and power grids, and in particular relates to a control method, device and terminal equipment of a multi-energy coupling system. Background technique [0002] Electrified railway, also known as electrified railway, is a railway that is mainly run by electric locomotives or EMUs, two types of railway trains (that is, commonly known as trains). Electrified railways are large-scale industrial users with distinctive characteristics, and the traction power supply system, as a typical impact load, has always had an impact on the national grid. At present, the main problems in the traction power supply system of electrified railways include: high basic electricity expenses, waste of regenerative braking energy, poor power quality, and low capacity utilization of traction transformers. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a co...
