摘    要:在电力系统数字保护中,用基波序分量来构成的保护方案已很多。本文分析了三种滤序算法的频率响特性,在此基础上提出了根据滤序频响特性设计数字滤波器的思想,并导出了三种滤波算法,可使滤序滤波算法在总体上计算量小、响应速度快、精度高。文中分析还表明,响应时间为1/3T和1/6T的滤序算法,在滤序滤波总体响应速度上可做到相近。

关 键 词:频率响应  序量保护  滤波理论

Abstract:Power frequency sequence components have been much used in the digital relay of power system. In this paper,the frequency responses of three algorithms of filtering sequence compo- have been analysed. On these basis,the paper provides an idea to design the digital filter and two thms of digital filter have been developed, which have the advantages of fast respondence, high uracy and less calculation amounnt. It has been pointed out that the responses of the filtering se- uence component algorithms of 1/3T and 1/6T with the developed digital filter are very similar.
Keywords:frequency response  phase sequence protection  filtering theory
