| 摘 要： | 提出了一种家用智能直流微网的架设结构,介绍了其主要特点。考虑到现实输电线路与负载都包含了少许感性成分,结合参考电压等级设计了一种用于低压配电网的小负荷直流断路器,并通过仿真验证其工作原理。仿真结果表明该断路器可以实现零电流机械开关的常规拉断,还可用作功率路由器的基本模块,为实现能量路由起到了重要作用。

Design and Application of New Type of Low-Voltage Direct Current Circuit Breaker in Direct Current Microgrid |
| |
| Abstract: | This paper put forward the erection structure of a kind of intelligent household direct current (DC) microgrid and introduced its main characteristics. In consideration of the actual transmission line and load containing a few inductive components, combining with the refer-ence voltage level, this paper designed a small load DC circuit breaker for low-voltage distribution network and its working principle was veri-ifed by simulation. Simulation results show that the circuit breaker could achieve zero current of a mechanical switching conventional snap and be used as a basic module of power routers, which plays an important role in the realization of energy routing. |
