A New Principle of Discrimination between Inrush Current and Internal Fault Current of Transformer Based on Self-Correction Function
前言：Abstract--When differential protective relays are applied to transformer protection,how to identify the magnetizing inrush current and short circuit current caused by internal fault is the key problem.Here,regarding the inrush current and short circuit current as the random signal,the sampled data are analyzed by correlation function principle in the digital signal processing （DSP）and the self-correlation function of the sampled data is calculated.Through the similar comparison operation conducted by standard self-correlation function (SSCF) formed with sinusoidal current the short circuit current and the inrush current can be distinguished by the magnitude of similarity coefficient.The results in Electrical Power Dynamic Laboratory (EPDL) verify the feasibility of the proposed method.Index Terms--Transformer,Differential protective relay,SSCF,Correlation function,Inrush current,Short circuit current,Random signal,EPDL.
正文：large power transformers are a class of very expensive and vital components of electric power systems.Accordingly,higher demands are imposed on the study of their protection techniques; this includes the requirements of dependability associated with no mal-operations,security associated with no false tripping,and operating speed associated with short fault clearing time.Protection of large power transformers is a very challenging problem in power system relaying

题目:一个新的原则涌流和之间的歧视的电流互感器内部故障基于自我纠错功能
前言:摘要——当差动保护继电器被应用到变压器保护,如何区分磁化涌流和短路电流内部故障引起是解决问题的关键所在。在这里,对于涌流和短路电流的随机信号的采集的数据进行了分析,相关的功能原则在数字信号处理(DSP)和自相关功能的采样数据计算。通过类似的比较运算进行自相关函数在标准SSCF)了正弦电流短路电流、涌流可以辨识的相似系数的大小。结果EPDL电力动态实验室)验证了该方法是可行的。指数的条件,变压器、微分保护继电器、SSCF、相关功能,涌流、短路电流信号,EPDL、随机。
正文:大电源变压器是一类重要组成部分昂贵,电力系统。因此,更高的要求的研究被课以保护技术,包括相关的要求没有mal-operations可靠性,安全相关的不虚伪绊倒对手,和运行速度短故障清除相关。电力变压器保护大是一个非常具有挑战性的问题在电力系统中的应用
