考虑支架特性的光伏电站技术经济分析
摘要:光伏发电中支架型式与发电能力紧密关联，为充分对比分析各类型支架技术经济性，以指导工程实践，选取固定式、固定可调、平单轴、斜单轴与双轴5种类型支架为研究对象，以新疆地区3个典型地点为例，采用METENONRM太阳辐照数据资源与PVSYST模拟软件，通过技术与经济指标的计算与分析，表明随着纬度增加，跟踪支架太阳辐照增益随之增长，阿勒泰跟踪支架的辐照量增益大于哈密与喀什，其中双轴跟踪支架辐照量增益最显著。上述3个地点光伏项目度电成本最优的支架类型分别为斜单轴、平单轴与斜单轴，均优于固定可调式支架。此外，各地区N型组件相较P型组件5种类型支架平均增发电量2.31%、2.34%、2.41%，且采用N型组件投资收益均高于P型组件。
Abstract：The type of bracket in photovoltaic power generation is closely related to the power generation capacity. In order to fully compare and analyze the technical economy of various types of brackets to guide engineering practice, this paper selects fixed, fixed adjustable, flat uniaxial, oblique uniaxial and biaxial five types of brackets as the research object, taking three typical locations in Xinjiang as examples, using METENONRM solar irradiation data resources and PVSYST simulation software, through the calculation and analysis of technical and economic indicators, it shows that with the increase of latitude, the solar irradiation gain of the tracking bracket increases, and the irradiation gain of the Altay tracking bracket is greater than that of Hami and Kashgar. Among them, the irradiation gain of the biaxial tracking bracket is the most significant. The optimal bracket types of photovoltaic projects in the above three locations are oblique uniaxial, flat uniaxial and oblique uniaxial, which are better than fixed adjustable brackets. In addition, compared with the five types of P-type components, the average additional power generation of N-type components in each region is 2.31 %, 2.34 % and 2.41 %, and the investment income of N-type components is higher than that of P-type components.
