| Abstract: | The zero-sequence current protection is an important means of power system ground protection. In traditional zero-sequence current protective relaying, whose settings are calculated in off-line mode, the optimal protection can not be achieved. After pointing out the shortcomings of traditional zero-sequence current protection, the paper expounds the basic principles and realization methods of adaptive zero-sequence current protection, and illustrates that the new protection can enhance sensitivity. |
