摘要
深入地研究了基于故障分量的数字式差动保护的基本原理,并与传统的比率制动差动保护作了详细比较,讨论了故障分量差动保护的动作判据,最后介绍了基于该原理的保护在实际中的应用。
This paper analyzes the fundamental principle of the fault component based digital differential protection and compares it with the conventional percentage restraint differential protection. Operation criteria for the fault component based differential protection are also discussed and the practical application of this principle in the protection of a generatortransformer unit is described in detail.
