摘要
在分析各种故障类型模分量特征的基础上 ,提出了基于模量小波变换能量特征的故障选相新原理和算法 ,并经过仿真计算和现场数据的验证表明该选相原理的正确性。对利用暂态量构成全线速动保护的影响因素进行了分析 ,提出尚需进一步研究的工作 ,并对研究工作进行了小结。
Based on the results of various model component analyses, a new fault phase selection method for EHV transmission line by the energy character from model component wavelet transform is proposed. The EMTP simulation and the recorded field data show that the method is correct. The influencing factors of nonun it ultra high speed transient based protection are analyzed, the research work is reviewed and the problems to be further studied are given.
