| 摘 要： | 对于光伏发电系统而言,最主要的问题是提高系统的效率和稳定性.为了克服传统两级式光伏并网系统在效率和稳定性上的不足,文中改进了单级式光伏并网系统电路拓扑和适用于此拓扑的最大功率点跟踪算法,并通过在Matlab Simulink环境中搭建仿真模型,模拟系统在外部光照发生变化时的输出特性并对其进行验证和研究.仿真结果显示该系统能够高精度地实现对光伏电池最大功率点的跟踪(MPPT),高效地通过逆变器将有功功率送入电网,且输入电网的无功功率可调.

| Abstract: | In photovoltaic technique, high efficiency and reliability are main problems to be solved. Two-level grid-connected photovoltaic system has obvious drawbacks with respect to efficiency and reliability. A novel method for simulating the work status of the PV cells and inverter using normal modules offered by the MATLAB software package is presented in this paper. The different output features are researched when the insolation are changed. The simulation results indicate that this system can track the maximu... |
