Description

一种盘式光伏跟踪器A disc type photovoltaic tracker

技术领域technical field

实用新型涉及一种光伏跟踪器,具体涉及一种盘式光伏跟踪器,属于太阳能利用技术领域。The utility model relates to a photovoltaic tracker, in particular to a disc-type photovoltaic tracker, which belongs to the technical field of solar energy utilization.

背景技术Background technique

目前,国际能源问题已成为各国关注焦点。化石能源的有效利用及新能源的开发利用成为科学家们研究重点。在化石燃料日趋减少的情况下,太阳能已成为人类使用能源的重要组成部分,并不断得到发展。太阳能的利用有被动式利用(光热转换)和光电转换两种方式,太阳能发电是一种新兴的可再生能源。太阳能发电成为目前清洁能源首选。At present, international energy issues have become the focus of attention of all countries. The effective use of fossil energy and the development and utilization of new energy have become the research focus of scientists. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. The utilization of solar energy has two ways: passive utilization (light-to-heat conversion) and photoelectric conversion. Solar power generation is a new type of renewable energy. Solar power has become the first choice for clean energy.

应中国“十二五”计划“推动能源生产和利用方式变革”。截至2015年,国内装机重量预达到13GW。目前采用的光伏发电装置主要采用:固定式电站、跟踪式电站、家庭式电站、离网式电站等种类。各种大型发电站采用集中式发电,也就是说需要集中占领大量土地面积才能达到集中发电的要求。其中,单轴光伏跟踪电站能提高(相比于固定角度的光伏电站)20-30%的电量。更有利于短期内收回成本。In response to China's "Twelfth Five-Year Plan" to "promote the transformation of energy production and utilization methods". As of 2015, the domestic installed capacity is expected to reach 13GW. Currently used photovoltaic power generation devices are mainly used: fixed power plants, tracking power plants, home power plants, off-grid power plants and other types. Various large-scale power stations adopt centralized power generation, which means that a large amount of land area needs to be concentrated to meet the requirements of centralized power generation. Among them, the single-axis photovoltaic tracking power station can increase (compared with the fixed-angle photovoltaic power station) 20-30% of the electricity. It is more conducive to recovering costs in the short term.
