基于信号振幅的输电线路故障诊断系统设计

Design of Transmission Line Fault Diagnosis System Based on Signal Amplitude

输电线路在电力系统中起着至关重要的作用,一旦发生故障,电力系统稳定性就将遭到破坏,电力供应中断,影响供电质量。快速准确地进行故障诊断,对电力系统可靠运行有着重要意义。提出了一种基于信号振幅的输电线路故障诊断系统。对故障信号特点做了分析,设计出系统诊断方案,最后详细介绍了该设计系统工作过程,并进行了总结与分析。

The transmission line plays a vital role in the power system. Once a fault occurs, the stability of the power system will be destroyed, and the power supply will be interrupted, affecting the quality of power supply. Fast and accurate fault diagnosis is of great significance to the reliable operation of power system. A transmission line fault diagnosis system based on signal amplitude is proposed.This paper first analyzes the characteristics of the fault signal, then designs the system diagnosis scheme, and finally introduces the working process of the design system in detail, and summarizes and analyzes.
