摘要
随着时代的发展,直流微电网已在很多方面得到了广泛的应用。相对于交流微电网而言,直流微电网具有无需跟踪频率以及电压相位、抗扰性更好、降低线路损耗、在基础设施的投资上较低等诸多优点,可见其未来的发展将不可估量。文中首先以直流微网的结构框架为基础,针对具体模块的关键技术等方面提出实现方案;同时设计了一种可以实现零电流关断的智能直流断路器的拓扑结构,并对该模块做了仿真设计验证;最后简单分析了该智能直流断路器的应用及发展。
With the development of the times, DC micro-grid has been widely used in many ways. With respect to the exchange of micro-grid is concerned, DC microgrid has no need to track the frequency and voltage phase; better immunity; reduce line losses; less investment in infrastructure, and many other advantages. It seems its future development will be immeasurable. Firstly, the structural framework of DC micro-grid based, proposing implementation based on the specific module of key technologies. Then, a topology is designed which can achieve zero current turn-off DC circuit breaker intelligent and verified the module. Finally, the application and development of the intelligent DC circuit breaker is analyzed.
