【摘 要】在科学技术水平提高和现代化社会发展的共同作用下,电力资源成为我国生产生活各个领域发展中不可或缺的资源之一,电力系统也因此被视作重要的供应系统。电力系统本身就是大型且安全隐患较多的作业系统,因此,对电力系统的继电保护十分关键,并且难度很大。基于此,论文分析了继电保护技术的相关概念,汇总了电力工程继电保护故障的成因,随后探究了电力工程继电保护技术的运用原则,最后分析了电力系统继电保护技术的未来发展趋势,以供相关人士交流参考。
【Abstract】Under the joint action of the improvement of science and technology level and the development of modern society, power resources have become one of the indispensable resources in the development of various fields of production and life in China. Therefore, power system is also regarded as an important supply system. The power system itself is a large-scale operation system with many security risks. Therefore, the relay protection of the power system is very critical and difficult. Based on this, this paper analyzes the related concepts of relay protection technology, summarizes the causes of relay protection faults in power engineering, then explores the application principles of relay protection technology of power engineering, and finally analyzes the future development trend of relay protection technology of power system, for relevant people to exchange and reference.

1 引言
当前,电力资源是人们生产生活中不可或缺的重要资源,供电系统也成为保证人们正常生活和稳定生产的主要能源系统,电力系统中的任何部位出现安全隐患都会影响整个电力系统的安全运行,甚至引发大面积停电现象。由此可知,电力系统的继电保护工作十分重要和关键。随着电力系统的改革和创新,电力系统的继电保护和维修工作的难度日渐提升。继电保护是在这种背景下提出的新型保护方式,改善了传统电力系统保护方式的缺陷和不足,融合了几种电力系统保护方式的优势,在现代供电网络当中发挥了重要作用。
