【Abstract】 After the large and huge capacity generators are put into the power system ,the requirements of improving performance and reliability of protection systems result in the research on relaying protection . On the other hand, the development of computer technology provides a powerful tool for applying new protection schemes and principles. On the basis of investigating present situation, this article surveys the newest development in numerical relay for large generators and further trend of the protective technology is predicted.更多还原
