Solar concentration electricity generating apparatus

Abstract

The invention provides a solar concentration generating set, wherein an optical collector is composed of at least one similar plane reflecting mirror light concentration unit, wherein the similar plane reflecting mirror light concentration unit is composed of a similar plane basement and a plurality of plane reflecting mirrors which are installed on the basement, each plane reflecting mirror is respectively provided with certain inclined direction and angles corresponding to the similar plane basement, each plane reflecting mirror can converge incident sunlight on the outer surface of a sunlight receiver, and the sunlight which is converged on the outer surface of the sunlight receiver has a shape which is basically corresponding with the outer surface of the sunlight receiver. The optical collector in the solar concentration generating set of the invention is composed of a plurality of similar plane reflecting mirror light concentration units, the disassembly is easy, simultaneously, and the precision demands to a tracker are not high, which is convenient for system upgrade and improvement.

Description

technical field [0001] The invention relates to a power generation device, in particular to a solar concentrated light power generation device. Background technique [0002] Concentrating solar photovoltaic power generation can greatly reduce the cost of photovoltaic power generation. With the continuous improvement of the efficiency of new high-efficiency concentrating cells, concentrating power generation systems will become more and more important in the field of solar photovoltaic power generation. There are many forms of concentrating optical systems. At present, the main application is the parabolic reflective point focusing system. The advantages of this system are: the battery with higher efficiency can be replaced; The concentration ratio can be very high, and the demand for batteries is reduced). But there are also the following disadvantages: First, the manufacturing precision of the reflector is high, and local errors will lead to uneven energy distribution on ...

AI Technical Summary

Problems solved by technology

But there are also the following disadvantages: First, the manufacturing precision of the reflector is high, and local errors will lead to uneven energy distribution on the surface of the battery, which is easy to form a focus on the surface of the receiver and cause damage to the receiver, or the light spot is too large to overflow the receiver. The reduction of power generation reduces the power generation efficiency; the second is a large parabolic reflection system, which is generally divided into small pieces during production, and then combined into a complete reflection system during system installation

The parabolic structure makes the assembly work very complicated, and large machinery must be used to help the work, which increases the difficulty of system installation
