摘要
电力系统暂态保护采用故障产生的高频信号检测故障，具有动作速度快，且不受系统运行方式的影响等优点．但其保护原理很难用解析式表达，不易进行精确分析．人工智能技术宜于对难以表述的知识进行分析处理，为暂态保护提供了有力的分析工具．介绍了暂态保护近期进展，分析了人工智能的特点。
Transient based protection utilizes the fault generated high frequency transient components to detect the occurrence of fault.It provides a fast response and high accuracy,and is not affected by power frequency.But it is difficult to express the transient based protection with equations.However,artificial intelligence provides an effecting analysis tool.This paper introduces recent developments in power system transient studies,including the application of artificial intelligence techniques and the newly developed transient based protection technology.
