摘要/Abstract

摘要： 针对部分城市配电网目前面临的变电站间负荷转供能力和平衡能力不足、变电站直送用户线路利用率不高等问题，通过总结国内外中压配电网网架的优势和不足，提出钻石型配电网的发展思路，阐述钻石型配电网的结构与特点，并初步提出钻石型配电网一次网架、自愈系统等方面的主要技术要求。通过与国内外典型网架结构在适应性、安全性、灵活性、可靠性与经济性等方面进行比较，详细分析钻石型配电网的技术经济特征，为实现城市配电网的转型升级和高质量发展提供解决方案。最后，以上海某区域为案例，分析现状配电网到钻石型配电网的演变过程，验证其技术经济特征。

关键词: 钻石型配电网, 负荷转供能力, 自愈, 高质量, 技术经济特征

Abstract: Urban power distribution networks in some cities currently have the problems such as the low load transfer capability and balance ability between stations, and the low line utilization for direct transmission between substations and users. Based on an investigation of the advantages and disadvantages of medium-voltage distribution networks both at home and abroad, this paper puts forward some ideas for development of diamond distribution network. The structure and characteristics of diamond distribution network are described, and the main technical requirements of primary grid and self-healing system for diamond distribution network are introduced. Through comparison of typical grid structures both at home and abroad in terms of adaptability, safety, flexibility, reliability, and economy, the technical and economic characteristics of the diamond distribution network are analyzed in detail, which provides a solution for the high-quality development of distribution network. Finally, a case study is conducted on an area of Shanghai, in which the evolution process from the current grid to the diamond distribution network is analyzed, and its technical and economic characteristics are verified.

Key words: diamond distribution network, load transfer capability, self-healing, high quality, technical and economic characteristics
