【摘要】：针对智能变电站继电保护存在的系统可靠性降低、运维难度增大等问题,阐述了基于即插即用就地化保护装置的新方案,用于提升保护可靠性和整站经济性。首先阐明了保护装置即插即用的理念和就地化安装的设计思路,并通过与当前智能站架构的比较,体现出新方案安全高效的优势。然后介绍了单间隔保护及跨间隔保护的应用方案、涉及的关键技术和面临的挑战;并就变电站全寿命周期内各类经济因子的变更进行比较,体现出新方案在变电站设计、建造、运维等方面的经济优势。目前,即插即用就地化保护装置已处于全面挂网试运行阶段。
[Abstract]:Aiming at the problems of lower system reliability and greater difficulty in operation and maintenance of relay protection in intelligent substation, a new scheme based on plug and play local protection device is presented. Firstly, the concept of plug and play of protection device and the design idea of local installation are expounded, and compared with the current intelligent station architecture. The advantages of security and efficiency of the new scheme are reflected. Then, the application scheme of single-spaced protection and trans-spacer protection is introduced, the key technologies involved and the challenges faced are introduced. Compared with the change of all kinds of economic factors in the whole life cycle of substation, it reflects the economic advantages of the new scheme in substation design, construction, operation and maintenance. Plug-and-play local protection device has been in the trial operation stage.
