摘要
以三电平DC/AC电源转换为研究对象,分析对比拓扑结构。从模块化的工程应用角度,采用改进T型方案开发出三电平DC/AC标准功率模块,介绍其结构及屏柜组装方式,以满足功率组合即插即用,并适应分布式光伏发电、分布式风力发电、储能、电动汽车等多应用场景。分析目前技术规范现状。基于交直流混合微电网的试验系统,阐述DC/AC模块在不同应用场景下的功能,并进行了试验验证。
Taking DC/AC power conversion as the research object, this paper comparatively analyzes topology structure. From standpoint of modular engineering application, three level DC/AC standard power module is developed based on improved T scheme and the structure and cabinet assembly are introduced in order to meet the power combination of plug and play, and then to adapt to photovoltaic power generation, wind power generation, energy storage, electric vehicles and other application scenarios. Current situation of technical specifications and standards are analyzed. The function of the DC/AC module in different application scenarios is illustrated and the experiments are carried out based on AC-DC hybrid microgrid test system.
