摘要:

随着直流形式分布式电源的发展、直流用电负荷比例的增高、储能装置使用的增多及敏感负荷对供电质量要求的提高,采用直流方式组织电源、储能、负载及监控装置构成的直流微电网将成为未来供用电领域的一种重要模式。本文在探讨直流微电网发展驱动力的基础上,描述了直流微电网的主要特征,给出了直流微电网的主要拓扑形式,并对当今国内外直流微电网发展的基本情况做了简要介绍,论述了直流微电网中的关键设备及相应的关键技术。论文分别从设备和系统层面探讨了直流微电网相关的控制策略,讨论了直流微电网故障方式及保护的主要问题。论文最后对直流微电网的发展趋势及应用前景做了简要展望。

Abstract:

Due to the extensive development of DC distributed generation, energy storage device, DC load and high requirement of power supply quality, DC micro-grid which is composed by DC sources, energy storage, loads and monitoring device, will become the important mode in the field of power supply and utilization in the future. Based on the analysis of driving force of DC micro-grid development, this paper summarizes the main features and topologies of DC micro-grid, and introduces the development scenario both at home and abroad. In addition, the key equipment for DC micro-grid is discussed. From the equipment and system level, the control strategies are investigated respectively. Then both the fault types and its protection are discussed. The further development and application prospect of DC micro-grid is forecasted in the end.

Key words: DC micro-grid, the field of power supply and utilization, topological form, coordination control strategy, fault protection
