摘要(Abstract)：

受线路结构、运行方式、干扰电压、地质情况等因素的影响,输电线路零序阻抗的测量结果会产生较大的误差,平行架设双回路线路的零序阻抗受影响程度尤其明显。对双回路线路零序阻抗进行理论分析,并对下乾1576线的零序阻抗进行现场测试,现场测试值与理论计算值吻合,可为线路零序阻抗测试提供借鉴。
Affected by the circuit structure,operation mode,interference voltage,geology and many other factors,there will be great errors in the measurement results of zero-sequence impedance of transmission lines.The influence on the zero-sequence impedance of parallel double-circuit lines is particularly evident.Through the theoretical analysis of zero sequence impedance of double-circuit lines,the field measurement of zero-sequence impedance for Xiaqian Line 1576 was carried out.The results are consistent with that of theoretical calculation.The research can serve as a reference for zero-sequence impedance measurements.
