电力系统输电线路距离保护装置分析

Transmission Line Distance Protection Device Analysis of Power System

随着国民经济的不断提升及现代化电网系统的不断升级,人们对供电可靠性和供电质量提出了更高的要求,而距离保护装置作为电网线路中最基础、最重要的保护设施对于确保整个电力系统的正常运行具有至关重要的作用,因此,对电力系统输电线路距离保护装置的研究不可或缺。本文首先介绍了距离保护装置的组成部分及原理,然后详细分析了其构成原则及性能特点,并就在具体应用中可能影响距离保护发挥作用的因素进行分析,以期为今后的电力系统输电线路距离保护装置研究工作提供参考。

With the continuous improvement of the national economy and the continuous upgrading of the modern power grid system,people have put forward higher requirements for power supply reliability and power quality, and distance protection devices as the most basic and important protection facilities in power grid lines play a vital role in ensuring the normal operation of the entire power system.Therefore, the study of distance protection devices for transmission lines of power systems is indispensable. This paper first introduces the components and principles of the distance protection device, then analyzes its constituent principles and performance characteristics in detail, and analyzes the factors that may affect the distance protection function in a specific application, in order to provide reference for the future power transmission line distance protection device research work.
