主动配电网保护研究综述

Research Review on Protection of Active Distribution Networks

考虑到主动配电网控制方式灵活、复杂、分布式电源渗透率较高、潮流双向流动等特性,依据主动配电网保护研究现有成果,对主动配电网保护技术做了综述,结合主动配电网的结构特征,提出对主动配电网保护的基本要求,讨论分布式电源和储能设备、故障时的隔离策略、控制方式、运行方式对主动配电网保护的影响。并分析主动配电网保护的关键问题和研究现状。

In light of the new fault characteristics of AND（active distribution networks）, such as flexible control method, bidirectional power flow, small fault current under fault condition, this paper reviews the ADN protection technologies. According to the existing researches, the basic requirements of ADN protection are proposed by combining the structure and fault characteristics of ADN protection. The effects of DG and controllable load,different isolation strategies, different control systems, different operation modes on ADN protection are then discussed. It summarizes the latest technology progress, the research objective and research direction.
