摘要
变压器空载合闸运行时会产生励磁涌流,当励磁涌流较大时,有可能造成电力线路保护装置发生误动作。文章分析励磁涌流产生原理,通过仿真分析变压器运行过程中有关性质特点,提出一些保障安全稳定运行的改善措施与方法。
Excitation inrush current will generate when the transformer without load is closed operation. When the exci- tation inrush current is larger, it may cause power line protection malfunction. The paper make an analysis of principle of excitation inrush current. Through the simulation analysis of the transformer operation process about the nature, the paper puts forward some measures and methods of the improvement on guarantee safe and stable operation.
