| 摘 要： | 完成了对光伏发电并网控制的设计及仿真.系统采用了两级式拓扑结构:前级用直流变换器进行最大功率跟踪及直流母线电压调整;后级用逆变器将直流电能逆变送入电网.为了实现对并网电流的精确控制使用了离散重复控制技术.最后,通过Matlab软件对上述设计进行了仿真校验,得到并网电流总谐波畸变率为1%,逆变器功率因数为97.91%.整体效率为87.4%.符合并网要求.

| Abstract: | The article makes a further research on the topic of grid-connected photovoltaic.Considering the characteristics of photovoltaie cells and grid requirements,two level topological structure is adopted in the system.In order to realize the maximum power point tracking and the bus voltage regulating.DC/DC inverter is used.The direct current will be converted into alternating current which is sent to the grid by the inverter.Among them,the repetitive control technology is applied to the inverter in order to achieve a precise control to the current.Finally.the simulation is done by using the Matlab.A set of experimental results carried out on a computer are provided to validate the proposed approach. |
