摘要
论述了最近两年变压器励磁涌流保护判据的研究现状,由附加相位判别的自适应二次谐波制动原理、半波傅立叶算法、不同区域平均等效瞬时电感比值到一些新型学科在涌流判据中的运用,并对其进行了分析和评价,最后提出了励磁涌流判据以后的研究方向。
The methods of identifying power transformer magnetizing inrush current in use are analyzed in the paper.Such as: an adaptive second harmonic restrained method using phase angle and amplitud e,half-wave fourier analysis,the ratio of average equivalent instantane ous inductance in different zones,and applying intelligent theory into the magnetizing inrush current.At last it puts forward the prospective criterion of magnetizing inrush current in future.
