Embodiment Construction

[0023] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0024] refer to figure 1 , The open-pit mine distributed new energy energy supply system of the present invention mainly includes a clean energy power generation system, a distributed energy storage system and a vehicle-mounted battery energy recovery system. The arrows in the figure indicate the direction of energy flow.

[0025] There are two main sources of electric energy required for pure electric trucks in the mining area, one is the power supply from the national grid, and the other is the distributed new energy supply system in the mining area. Compared with the traditional centralized power supply method, the use of distributed new energy energy supply system for power supply can make up for the lack of security and stability of the power grid, and effectively improve the safety and reliability of power consumption in mining areas. In...

Abstract

A distributed new energy supply system for a strip mine comprises a clean energy power generation system, a distributed energy storage system and a vehicle-mounted battery energy recovery system, and the invention further provides a configuration method of the distributed new energy supply system, and the configuration method comprises the steps that the battery energy recovery coefficient, the comprehensive power consumption under the unit freight distance, the daily charging demand of a single pure electric truck and the annual load power consumption of a mine area are calculated; and the layout area of the photovoltaic module and the installed capacity of the distributed energy storage system can be further calculated. The energy utilization efficiency of strip mine production can be improved, and the stability of a mining area power supply system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of open-pit mine production and mining, and at the same time belongs to the field of distributed energy applications, in particular to an open-pit mine distributed new energy energy supply system and a configuration method thereof. Background technique [0002] By reducing carbon emissions in the transportation of open-pit mines and building a clean energy mining and transportation method, it will be conducive to the sustainable development of mine ecology. In recent years, due to the advantages of high transmission efficiency, clean and low-carbon transportation process, pure electric trucks have been gradually used in mine transportation. The construction of new energy charging stations in open-pit mines can provide a source of power for pure electric trucks. However, charging stations generally have the characteristics of large power consumption and large load fluctuations. Therefore, the energy supply s...
