基于微机继电保护装置的集成化保护和控制系统设计

Design for integrated protection and control system based on microprocessor relay device

针对继电保护装置中存在的有待改进的地方,提出了新型的设计思路。集成化保护和控制系统设计可有效改善保护和控制系统的性能,提高可靠性、耐用性以及容错功能。论述了容错型集成化控制系统依据N-1原则的实现方法,并对集成化设计中的特殊功能进行了具体探讨,如各组继电保护装置同步问题、自动闭锁和复原、高频自动关闭以及延时断路器保持,得到了较为理想的集成化保护和控制系统设计。

Based on that the current relay protection device needs to be improved, this paper proposes a new design thought. Integrated protection and control system can be effective in improving the protection and control system performance and increasing reliability, durability, and fault tolerance. This paper discusses the realization approach to fault-tolerant integrated control system based on N-1 principle, and details special features in the integrated design, such as synchronization of protective relaying devices in each group, automatic blocking and recovery, high-frequency automatic closing, as well as the self-closing delay of the circuit breaker. Thus an ideal design for integrated protection and control system is obtained.
