两种形式太阳能并网逆变电源发电效率的研究

On the Efficiency of Grid-connected Inverter Solar Power Generation

阐述了当前太阳能发电系统和太阳能光伏发电系统的结构、原理和特点。对太阳能发电过程中单台大功率逆变电源和小功率模块组成的逆变电源在发电效率上的优势进行分析研究,对以上两种情况下,MPPT路数和发电效率的的关系。

The article focuses on the structure,principle and features of solar power energy generation system and photovoltaic power generation system.It compares the solar energy power generation efficiency between single high-power inverter and inverter made of low-power modules,analyzes the advantages and disadvantages of both ways,and also defines the relation between MPPT number of strings and generation efficiency under the two circumstances.
