【摘要】：针对常规变电站、智能变电站线路保护工程应用中面临的保护速动性、可靠性和运维方面的难题,提出了一种基于SOC芯片实现的功能纵向集成、无防护安装的就地化线路保护系统架构和技术方案。通过一体化设计,纵向集成单间隔合并单元、保护和智能终端功能,减少设备类型及数量,简化配置,减少信号中间传输环节,缩短保护动作时间,并为站域保护等站端设备提供数据采集和控制执行支撑。同时对就地化线路保护的站间同步采样、远方不停电传动、同期电压接入等关键技术进行了研究与分析。对就地化保护的关键性能进行测试实验和比对分析,实验结果验证了所述方案的有效性和先进性。
[Abstract]:Aiming at the problems of protection rapidity, reliability and operation in conventional substation and intelligent substation line protection engineering, a vertical integration of functions based on SOC chip is proposed.Non-protective installation of local line protection system architecture and technical scheme.Through integrated design, longitudinally integrated single interval merging unit, protection and intelligent terminal functions, reduce the type and number of equipment, simplify the configuration, reduce the signal intermediate transmission link, shorten the protection action time,It also provides data acquisition and control execution support for the station terminal equipment such as station domain protection.At the same time, the key technologies of local line protection, such as synchronous sampling between stations, remote transmission without power outage, simultaneous voltage access and so on, are studied and analyzed.The key performance of in situ protection is tested and compared. The experimental results show that the proposed scheme is effective and advanced.
