Discussion on Fault Analysis and Treatment Strategy in Power System Relay Protection

摘要

电力系统要安全稳定运行，这对国家经济和社会生活十分关键。而继电保护则是捍卫电力系统安全的第一道屏障，本文意在深入探究继电保护领域的关键部分：故障分析及应对策略。文章先全面整理了电力系统中常见故障的基本种类，短路故障，接地故障以及断线故障等，然后细致论述了针对这些故障的分析手段，覆盖故障信息收集，特性分析并做到精准定位。在此基础上，论文着重论述了保护装置出现异常时的处理办法，还有故障发生之后的一系列应对措施，包含隔离，复原和防范等方面。对于处理效果的考量以及持续改善机制展开探讨，从而创建起较为完备且严谨的故障防御体系，以此来优化电力系统的整体可靠性。

Abstract

The safe and stable operation of power systems is crucial for national economic development and social stability. Relay protection serves as the primary safeguard for electrical infrastructure. This paper focuses on analyzing critical components of relay protection systems, particularly fault diagnosis and mitigation strategies. The study first systematically categorizes common power system faults, including short circuits, ground faults, and line breakage faults. It then details analytical methodologies for these faults, covering fault data collection, characteristic analysis, and precise fault localization. Building on this foundation, the paper emphasizes troubleshooting approaches for malfunctioning protective devices and post-fault response protocols encompassing isolation, restoration, and preventive measures. Through evaluating implementation effectiveness and establishing continuous improvement mechanisms, the research aims to develop a comprehensive and robust fault prevention framework, thereby enhancing the overall reliability of power systems.
