| 摘 要： | 目前的稳定控制装置线路跳闸判据由于没有考虑电流互感器二次残流的影响，直接影响了装置的正确判断。通过对电流互感器二次残余电流的理论分析，提出了改进目前稳控装置跳闸判据的措施，同时也对跳闸判据的合理应用提出了建议。

| Abstract: | The correct judgment of security and stability control equipment is depending on the judgment of AC transmission line trip, and thus the equipment sometimes works incorrect due to the influence of the remaining current of CT second winding which hasn't been considered in current trip criterion. This paper analyzes the influence of the remaining current, resulting in the improvement of line trip criterion and the advice for the reasonable application of the criterion. |
