Optical fiber conduction solar photovoltaic power generation system

Abstract

The invention discloses an optical fiber conduction solar photovoltaic power generation system, which comprises a light collection unit, a conduction unit and a power generation unit. The light collection unit is of an optical fiber light collection layer structure and comprises a reflection layer and an optical fiber braided layer which are sequentially arranged from bottom to top, and the optical fiber braided layer is braided into a surface by an optical fiber bundle without a cladding. The conduction unit is an optical fiber conduction device. The input end of the optical fiber conductiondevice is connected with the tail end of an optical fiber bundle of the fiber braid, and the output end of the optical fiber conduction device is connected with the power generation unit. Compared with a traditional light collector, the optical fiber light collecting layer structure has the advantages that the adopted optical fiber weaving layer is low in cost, simple in structure, convenient to manufacture and the like, a complex optical element light collecting system and a sunlight positioning and tracking system of the traditional light collector are omitted, and the sunlight collecting efficiency of optical fibers is improved.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to an optical fiber conduction solar photovoltaic power generation system. Background technique [0002] The solar photovoltaic power generation system converts the sun's light energy directly into electrical energy through solar cells for external output. It is mainly divided into two categories: concentrating power generation systems and non-concentrating power generation systems. The concentrating power generation system is mainly composed of solar cells, concentrators, and sunlight positioning and tracking systems. The application of concentrators can focus sunlight to a receiving surface (solar cells) that is 1 / 10 to 1 / 1000 or even smaller than the incident surface In general, compared with non-concentrating power generation systems, concentrating power generation systems can greatly reduce the use area of ​​solar cells and improve system conversion e...

Problems solved by technology

[0003] However, the concentrating power generation system has the following problems: (1) The structure of the concentrator is precise and complex, and the overall design and manufacture are difficult; (2) The solar positioning and tracking system has high requirements for the long-term reliability of the system operation, so further Increased overall construction cost and operation and maintenance costs

[0009] This technical solution is firstly used for indoor lighting. Although optical fiber is used for optical fiber transmission, the lighting unit still has the problem of precise and complex structure, and the positioning unit is required to cooperate with tracking the sun, and the operating cost is relatively high.
