| 摘 要： | 本文提出一种新型的数字式横差保护方案，其定值能够自适应地随着发电机运行状态的变化而变化，与传统的模拟式横差保护相比，其动作灵敏度大大提高。正序突变量闭锁元件的设置，使得保护在发电机外部故障时具有足够的安全性。

| Abstract: | This paper presents a project of an adaptivedigital transverse differential protection, the setting value ofwhich can be automatically regulated according to the operating state of generator. The sensitivity of protection basedon this project is much higher than that of traditional analogue protections, and because of configuring the positivesequence blocking element the misoperation of the protection can be effectively prevented when short circuit fault occurs outside the generator. |
