The traditional fault location method based on impedance can not overcome the effects of transitionresistance, etc.
传统的阻抗法进行故障定位，难以克服过渡电阻等因素的影响。

Therefore, in order to act correctly and timely, a reasonable protection scheme is put forward to avoid the influences of the transitionresistance and the in-series compensation equipment.
因此，本文的目的是提出合理的保护方案，消除过渡电阻和串联补偿的影响，实现保护的正确、及时动作。

The sensitivity of the proposed protection scheme is not impacted by the factors such as transitionresistance, lightning stroke, fault type, load current and operating mode of power system.
