摘要
数字化变电站的推广给包括安全自动装置在内的二次自动化设备带来了新的挑战,也带来了新的机遇。重点介绍了安全自动装置应用于数字化变电站过程中的4项关键技术,包括稳定控制和备自投功能一体化设计,CT量程智能切换,旁代状态智能识别,以及多测试仪的协同测试技术。这些新技术的采用,使数字化变电站的技术优势在安自装置的实际应用中得以充分发挥,同时为日后该类型安自装置在数字化变电站大规模铺开应用打下坚实的技术基础。
The promotion of digital substation brings new challenges as well as new opportunities to the secondary automation equip- ments including automatic-security device. This paper mainly introduces four key technologies applied to the automatic-security device used in the process of digital substation. The four key technologies includes stability control and spare power automatic switch function integration design, CT range intelligent switch, the generation of state intelligent identification, and tester collaborative testing tech- nology. These new technologies will give full play to the practical application of automatic-security device in digitized substation tech- nology. In the future, these four key technologies will lay a solid technical foundation for the security automatic device＇ s large-scale application in digital substation.
