摘要
利用变电站采样信息,提出了一种实现区域层次化继电保护的方式。系统主要由通信网络组成、变电站层,区域保护层。通信系统将就地信息传送至区域保护,实现区域信息共享。在获取变电站层的全景信息后,区域保护系统根据电力系统运行方式、拓扑结构与各供配电线路的故障类型与负荷发生变化,和就地保护进行配合,利用区域信息进行故障定位,实现了面向系统的保护。
Using substation sampling information, this paper proposes a realization method for zone area hierarchical protection system. The system is mainly composed of communication network, substation regional protection level and zone area hierarchical protection level. The informations will be sent to the regional protection by communication system, which realizes regional information on sharing. Finally, after obtaining substation panoramic information, according to power system operation, typology structure, and the change of fault types and load of each power supply and distribution line, zone area hierarchical protection cooperates with the regional protection, uses regional information for fault location, and realizes the system oriented protection.
