摘要
在适用于模块化的DC/DC双向换流器和AC/DC双向换流器的主电路拓扑结构下,分析柔性配电网提供即插即用的交直流接口等功能。针对系统内部多接口换流器并联于内部直流母线上和外部每一条功率链路连接于两个互联接口换流器的特点,设计系统物理组成要素。利用电力电子变换器的隔离单元和电力电子器件本身的开关特性,设计通信结构。经过试验,验证了所提方法具有突出的技术优势和较高的自动化检测能力。
Under the premise of the main circuit topology structure suitable for modular DC/DC two-way converters and AC/DC two-way converters,this paper analyzes the flexible distribution network to provide plug-and-play AC and DC interfaces and other functions.The physical components of the system are designed according to the characteristics that the internal multi-interface converter is connected to the internal DC bus in parallel and each external power link is connected to two interconnecting interface converters.The communication structure is designed by using the isolation unit of the power electronic converter and the switching characteristics of the power electronic device itself.After experiments,this research method has outstanding technical advantages and high automatic detection capabilities.
