摘要：
This paper suggests a new adaptive single-pole auto-reclosing technique based on tracking a single harmonic distortion index (HDI) that represents the behavior of the low frequency components of the faulted phase voltage or sound phase current waveforms and a decision-making index that is defined based on properties of the tracked HDI. The advantage of this technique is that the threshold values, set for indices, can be chosen almost independent of pre-fault loading conditions and line parameters.
