摘要
在现代电力系统中,分布式电源配电网因其高效和灵活的特点日益受到重视.分布式电源配电网指在传统电网基础上,融合多种小规模的发电资源,如太阳能、风能等,其一般接入低压或中压配电网.该配电网的结构特点包括复杂的拓扑结构、多样的电源类型及可变的负载需求,因此使故障诊断与定位成为确保其可靠性和稳定性的重要挑战.文章通过综合分析分布式电源配电网的基本概念、结构特点、故障特性,深入探讨当前在故障诊断与定位方面的主要方法,包括电气量测量法和时间同步技术.
Abstract
Distributed power distribution networks are increasingly valued in modern power systems due to their high efficiency and flexibility.Distributed power distribution network refers to the integration of various small-scale power generation resources,such as solar energy,wind energy,etc.,on the basis of traditional power grids.Power generation resources are generally connected to low-voltage or medium voltage distribution networks.The structural characteristics of this power grid include complex topology,diverse power source types,and variable load requirements,making fault diagnosis and localization an important challenge in ensuring its reliability and stability.This article comprehensively analyzes the basic concepts,structural characteristics,and fault characteristics of distributed power distribution networks,and deeply explores the main methods in fault diagnosis and positioning,including electrical quantity measurement method and time synchronization technology.
