微机发电机差动保护

Digital Differential Protection for Generator

介绍了各种微机发电机差动保护的原理。针对在差动保护中长期存在的比如差动保护灵敏度、制动系数和斜率的区别、ＣＴ断线等一些比较有争议的概念，文章给予了详细合理的分析，并提出了作者自己的观点。

It presents several principles of differential protection for generators.In accordance with the arguments concerning protection such as sensitivity,restraint factor,slope of operating characteristic,CT secondary break and so on,a rational analysis is given in detail and some ideas of authors are proposed.
