基于等效瞬时电感频域特性的配电网励磁涌流识别方法研究

Identification of Distribution Network Inrush Current Based on Equivalent Magnetizing Inductance Frequency Characteristics

变压器等效励磁电感能够反映其铁心的饱和程度。根据等效瞬时电感在涌流故障情况下瞬时励磁电感波形的差异性,提出一种基于等效瞬时电感频域特性的配电网励磁涌流判别方法。通过试验验证了该方法的可靠性。

For the equivalent magnetizing inductance of the transformer can reflect the characteristics of its core saturation, an inrush current identification method which is based on the equivalent magnetizing inductance frequency characteristic is proposed in this paper. The test results of a large number of simulations verify the correctness and effectiveness of the method.
