基于故障录波数据保护动作分析软件的实现
Implementation of Protection-action Analysis Software Based on Data of Recorded Fault
【摘要】 通常故障录波装置提供的故障数据分析软件难以满足继电保护及断路器动作分析的相关数据要求,作者提出了一种基于故障录波数据的评价保护动作的分析方法,并开发了相应的软件,介绍了软件设计方案和主要功能。重点介绍了保护算法:录波数据预处理的主要算法、基频分量算法、测量阻抗算法、相量突变量检测算法等,软件设计方案的实现。
【Abstract】 Usually it is difficult for fault data analysis software provided together with fault recorder to satisfy the requirement of analysis of protection action,of corresponding data of ability of circuit breaker interrupters.The authors propose an method of analysis protection of evaluation action by use of fault data recorded by microcomputer based fault recorder data and develop corresponding software.The design principle and main function of the developed software are presented.Emphatically the main analysis and calculation methods,such as the main algorithm of recorded data preprocessing,algorithm of fundamental frequency component,algorithm of measured impedance,detection algorithm of phase’s abrupt change,are described.The designing software program is given.
