摘　　要：通过对光伏并网系统的分析,论述了并网控制器的功能,并详细设计了以TMS320LF2812为核心的并网控制器的硬件电路,为了提高控制器的实时性能,系统以μCOS-Ⅱ作为软件平台,利用RMS优先级选择算法为并网控制器各个任务确定了优先级。通过对系统总体任务关联分析得出实时多任务间相互关联的结构,并给出了各任务设计的具体方法。从实验结果可以看出,系统在操作系统控制下运行情况良好,证明了设计的正确性。Through the analysis of photovoltaic grid-connected system,the grid controller＇s functions have been discussed, and the hardware circuit of the grid-connected controller with the TMS320LF2812 as the core has been designed. In order to improve the controller＇ s real-time performance, the μCOS-II is taken as the system software platform,and the priority for each task of grid-connected controller is identified by using RMS priority selection algorithm. Through the analysis of the overall mission of the system, here comes to a real-time multi-task correlation analysis between the interconnected structure, the task of designing specific methods are given. The experimental results show that the system under the control of the operating system is running well, and prove the correctness of the design.
