| 摘要: |
| 基于实时数字仿真系统RT-LAB建立典型“手拉手”拓扑，含分布式能源光伏、锂电池以及交直流负载的直流配电网实时仿真数学模型。利用该模型对柔性直流配电系统的启停控制、指令控制等运行方式进行暂态响应特性仿真分析。RT-LAB实时仿真技术显著增强柔性直流配电网系统仿真的时效性和实用性。配网启动逻辑设计及软开关技术、逐级功率提升法的应用，有效减小了直流配电系统启动电流冲击及接入操作过电压。系统建模满足直流配电系统运行要求，对其启动控制及运行工况的仿真分析，为柔性直流配电工程建设进一步研究提供参考。 |

| Abstract: |
| Based on the real-time digital simulation system RT-LAB, this paper establishes a typical mathematical simulation model of loop flexible DC distribution. The model includes photovoltaic, lithium batteries and AC/DC load. Simulation analysis of different running conditions transient response tests, such as start-stop control, command control, is made. RT-LAB significantly enhances flexible DC distribution simulation timeliness and practicability. Start-up logic design, soft-switching and progressive power upgrade method effectively reduce starting current and access operation over-voltage. It is proved that the model works well to meet the operational requirements, and the study about start-stop control and operation conditions can provide reference for further engineering construction. |
