摘要
随着全球的环境污染和能源危机的增加,目前光伏并网发电系统正成为太阳能系统应用发展的趋势。基于DSP芯片TMS320F2812,搭建了一套10 kW单相光伏并网逆变器,该系统具有最大功率跟踪和反孤岛效应等功能,并网逆变器的输出控制为电流源系统,保证输入的直流电压尽可能快的进行调整,该系统向电网输送的电能质量优于IEEEStd.2000-929和UL1741的标准要求。现场运行结果表明了所提出的控制方案具有良好的动态和稳态性能。
With the global environmental pollution and the increasing serious energy crisis today, grid-connected photovoltaic (PV) system is becoming the development trend of photovoltaie system's application. A 10 kW single-phase grid-connected inverter based on DSP TMS320F2812 with the functions of maximum power point tracking and anti-islanding effects was discussed, and the system was designed as a current-source system, the DC voltage was adjusted as fast as possible with little overshoot,which the power quality into the grid is better than the standard of IEEEStd. 2000-929 and UL1741.It has been shown from field results that: the proposed scheme provides both good dynamic and steady-state performance.
