| 摘 要： | 在变压器差动保护平衡系数计算中,基本侧选取不同,将直接影响差动门槛（差动保护最小动作电流）的整定。在研究变压器差动保护平衡系数对差动门槛整定的影响基础上,探讨了目前存在的4种基本侧选择方式,并提出了差动门槛整定与基本侧的对应关系,有助于整定人员对变压器保护装置的差动门槛进行合理整定。

| Abstract: | At the equilibrium coefficient calculation, differential protection setting is influenced by the selection of basic side. On the foundation of equklibrium coefficient influence research, the four selections mode of basic side was discussed, and the congruent relationship of differential protection setting with basic side was put forward, which is contribute to differential protection setting. |
