The traditional fault location method based on impedance can not overcome the effects of transition resistance, 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 transition resistance 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 transition resistance, lightning stroke, fault type, load current and operating mode of power system.

该保护方案的灵敏度不受过渡电阻、雷击、故障类型、负荷电流、系统运行方式等因素的影响。

Thus, the proposed adaptive criterion can effectively improve the sensitivity of generator protection is improved while the single-phase of stator winding is grounded via transition resistance.

因此，自适应判据有效提高了保护在定子绕组经过渡电阻单相接地情况下的灵敏度。

Therefore, the present situation is one of transition from partial to total resistance .

此，目前是处在从片面抗战到全面抗战的过渡期中。
