摘要

接地系统阻抗的测量会受到电力系统频率干扰及其谐波的影响。移频法(SFM)对电磁干扰不敏感。本文针对水电厂连接的架空线路的两种不同负荷情况，对该方法进行了评价。现场试验结果进一步验证了SFM方法的正确性。

Grounding system impedance measurement using shifted frequency method

The measurement of grounding system impedance may be affected by power system frequency interference and its harmonics. The Shifted Frequency Method (SFM) is potentially insensitive to the electromagnetic interference. In this paper, we evaluate this method in the hydroelectric power plant for two different load conditions of the connected overhead power lines. Presented field tests results further validate and justify the SFM method.
