摘要:
      目前,中压直流配电网的应用场景、基本特性及其系统设计还缺乏系统性论述。首先,从供电能力、互联作用、相互支撑、短路电流抑制作用等系统特性方面论述了中压直流配电网的应用场景、特点及优势。然后,从工程实现的角度论述了中压直流配电网设计的关键技术,涵盖电压水平的确定、网架设计、接线方式、接地方式的选择等关键技术。最后,指出了中压直流配电系统发展与应用还应考虑的问题。
Abstract:
      The application scenarios, basic characteristics and system design of medium-voltage DC distribution network are lack of systematic discussion. Firstly, the system characteristics of power supply capacity, interconnection, mutual support and short-circuit current suppression are discussed to show the application scenarios, characteristics and advantages of medium-voltage DC distribution network. Then, key technologies of design for medium-voltage DC distribution network are also given in the view of engineering realization, including the determination of voltage level, grid design, wire model and grounding mode selection. Finally, the problems that should be considered in the development and application of medium-voltage DC distribution system are presented.
