文檔介紹：光伏发电是未来新能源发电重要方向之一，而光伏变流器是光伏发电系统的核心。介绍一种基于微网理念的光伏变流器设计。以该变流器为核心的光伏发电系统可以看做一个小型的微网系统。该系统能根据外部电网情况，工作于并网模式和离网模式。介绍了该系统的各个组成部件的设计以及变流器主电路部分器件的选型。最后，由实验样机进行测试。试验结果验证了电路拓扑结构及控制方案的可行性，也说明了系统参数设计方法的正确性。 Solar Photovoltaic generation is an important direction of new energy power generation in the future，while photovoltaic converter is the core of photovoltaic generation system. This paper deals with a study on photovoltaic inverter based on the concept of microgrid. This paper describes a system whose core component is the photovoltaic inverter，can work on grid-connected mode or run independently according to the external situation. The paper simply describes the main components of the system. At last，the prototype was produced and tested. Test result has proved feasibility of circuit topology structure and controlling scheme and shown correctness of system parameters. Key words: PV inverter； microgrid； off-grid； storage battery
