【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特性分析的要求,文章提出了一种采用微机故障录波数据的保护特性分析方法,并开发了相应的软件,介绍了软件设计原则和主要功能。重点介绍了主要的分析和计算方法:录波数据预处理的主要算法、基频分量算法、谐波分析算法、相量突变量检测算法、测频算法、故障类型与相别判断方法、测量阻抗轨迹显示方法、继电器动作校验方法。对软件的使用方法和应用示例进行了简要说明。更多还原

【Abstract】 Usually it is difficult for fault data analysis software provided together with fault recorder to satisfy the requirement of protection characteristic analysis.The authors propose a protection characteristic analysis method by use of fault data recorded by microcomputer based fault recorder 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,harmonic analysis algorithm,detection algorithm of phasor’s abrupt change,frequency measurement algorithm,discrimination method of fault kind and faulty phases,locus display of measured impedance and verifying method of relay action,are described.A concise illustration of this software’s usage and application example is given.更多还原
