在现代电力系统中,变电站的直流系统是保证电力传输和分配稳定性的关键组成部分。异极环网是一种特定的网络布局,通常应用于直流系统以增强其可靠性。在这种配置中,系统设计允许在一条路径出现故障时,通过另一条路径继续传输电力。然而,即使有这种高度的冗余设计,故障的发生仍可能导致严重的运行中断和服务质量下降。因此,开发高效的故障处理与修复技术对于维持系统的高效运行和可靠性至关重要。文章介绍直流系统异极环网的基本概念及其在变电站中的应用,研究异极环网的故障处理与修复技术,旨在提出一套完整的故障响应和系统恢复框架,以提升变电站直流系统的可靠性和效率。

In modern power systems,the direct current system of substations is a key component to ensure the stability of power transmission and distribution.Heteropolar ring network is a specific network layout commonly used in direct current systems to enhance their reliability.In this configuration,the system design allows power to continue to be transmitted through another path in the event of a fault in one path.However,even with such a highly redundant design,the occurrence of faults can still lead to serious operational interruptions and a decrease in service quality.Therefore,developing efficient fault handling and repair technologies is crucial for maintaining the efficient operation and reliability of the system.This article introduces the basic concept of direct current system heteropolar ring network and its application in substations.It studies the fault handling and repair technology of heteropolar ring network,aiming to propose a complete fault response and system recovery framework to enhance the reliability and efficiency of substation direct current system.
