Railway space integrated power generation system adopting wind energy and solar energy grid connection and piezoelectric technology

Abstract

The invention relates to a railway space integrated power generation system adopting wind energy and solar energy grid connection and a piezoelectric technology. The technical feature of the railway space integrated power generation system is that the system comprises a solar energy power generation module, a wind power generation module, a piezoelectric module and an electric energy control apparatus, wherein the solar energy power generation module is connected with solar battery panels which are mounted on the side surfaces of railway guard bars, railway slopes and the middle parts of rails separately; the wind power generation module is connected with small-sized wind-driven generators mounted at the top ends of the railway guard bars and a wind-driven generator set mounted on train guard bars separately; the piezoelectric module is connected with piezoelectric crystals mounted between the rails and rail bearings; and the electric energy control apparatus is connected with the solar energy power generation module, the wind power generation module, the piezoelectric module, a power load and a power grid to realize power supply of the power load, grid connection and compensation. By adoption of the railway space integrated power generation system, cleaning energy of solar energy, wind energy and the like can be provided for railway traction transportation, so that pollution caused by utilization of conventional coal power is reduced, and land utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power generation, in particular to a railway space integrated power generation system utilizing wind and solar grid connection and piezoelectric technology. Background technique [0002] Electrified railway transportation has been continuously developed and popularized. However, at present, my country's electricity is still dominated by coal power. Coal power not only faces the shortage of coal resources, but also causes air pollution in the production process. It has become very necessary to use clean and renewable energy in railway transportation. [0003] Regarding the use of land for new energy industries such as wind energy and solar energy, my country proposes to encourage a development model that does not occupy land and does not change the form of land. Making full use of the railway infrastructure and the land and space along its lines for clean energy development can not only improve the utiliz...
