Problems solved by technology
[0006] The conductive parts inside the pipeline need to use conductive materials with very low resistivity. The high-temperature superconducting materials required for power transmission in LNG shared pipelines are currently difficult to form into a line, resulting in high costs. In addition, the insulating support inside the LNG pipeline The skeleton needs materials that can withstand the low temperature of LNG, so its cost is also high
[0007] That is to say, the overall cost of the power transmission system is too high due to the high manufacturing cost of the conductive part and the insulating support frame suitable for the superconducting energy pipeline
[0008] In addition, directly adding high-voltage wires inside the pipeline for power transmission may also affect the ground potential of the shared pipeline, especially in the case of a ground short circuit, the large current of the pipeline to the ground will affect or even destroy the pipeline potential monitoring and anti-corrosion measures

The invention discloses a power transmission method and system based on a transmission pipeline. The method comprises the steps that a high-frequency generator converts the current of a transmitting-end power grid into electromagnetic wave energy of a frequency matched with a transmission pipeline at the power transmitting end of the transmission pipeline; a first electromagnetic wave conduit connected with the high-frequency generator is used for guiding the electromagnetic wave energy into the conveying pipeline through a transmitting antenna; and at the receiving end of the conveying pipeline, a second electromagnetic wave conduit connected with a high-frequency receiver is used for converting electromagnetic wave energy received from the conveying pipeline into electric energy through a receiving antenna. According to the invention, the structure of the whole power transmission system can be simplified, and the insulation and conductor overall cost of the system is reduced.
Description
technical field [0001] The invention relates to the field of electric power, in particular to a method and system for power transmission based on transmission pipelines. Background technique [0002] The long-distance transmission of electric energy in the traditional way generally requires separate construction of transmission lines, using three-phase AC transmission or positive and negative DC transmission. [0003] In recent years, emerging pipeline transmission, GIL gas insulated pipelines or oil and gas transmission pipelines, all transmit power by adding conductive wires inside, and use power frequency AC or DC for power transmission, including the superconducting power transmission research project of LNG pipelines-《 Superconducting direct current transmission / gas transmission integrated energy pipeline" realizes the co-transmission of electricity and LNG. [0004] In the above-mentioned integrated power transmission / gas transmission energy pipeline (referred to as s...
