摘　　要：本文结合同杆双回线的特点,引入六序故障分量,从理论上对同杆双回线的25类120种故障条件下六序故障分量的幅值和相位关进行了分析,给出了在不同故障下六序故障分量的特征,为进一步研制新型同杆双回线保护提供了理论依据。This paper, combining the characteristics of Double-circuit line on the same pole(DLSP), introduces the Six-sequence fault components into fault analysis. Formulas of Six sequence fault components for 25 fault types and 120 kinds of fault which would occur on DLSP are derived. By summerizing the formulas, the characteristics of both phase and amplitude are obtained. According to the characteristics, distinguishing features of all fault types will be provided. The method mentioned in the paper highlights a new protection for DLSP.
