2kW沼光互补一体化智能发电系统研究

以当前广泛研究的新能源（太阳能、沼气）应用为研究对象,介绍了沼光互补一体化智能发电系统的组成及光伏逆变器和智能控制板的软硬件设计。光伏逆变器采用单相全桥结构,基于TMS320LF2407 DSP实现了反孤岛检测控制和MPPT控制。智能控制器通过电压、光强采样,实现了沼气发电、太阳能发电和蓄电池供电的智能切换和太阳跟随控制。经组装测试,系统成功实现了沼光互补发电,技术指标达到了工业级要求。

Research on 2 kW Intelligent Power Generation System of Biogas and Solar Integration

Based on application of new energy（such as solar,biogas）,the composition of an intelligent power generation system,and the software hardware design of photovoltaic inverter（PV）and intelligent control plate are elaborated.The single-phase full bridge structure is adopted in PV.The anti-islanding detection control and maximum power point tracking（MPPT） control were realized based on TMS320LF2407 DSP.The intelligent switch over the biogas power generation,the solar power generation and battery power supply was realized with the intelligent controller,with which the solar tracking control was also realized.
