摘    要:智能变电站数字化保护是将变电站信息采集、传输、处理、输出过程全部数字化,通过分层、分布式通信网络传输,实现全站信息共享。由于超高压变电站动态电磁环境、温度等因素影响,采集电路易受干扰,严重影响采样过程和数据同步。解决这一难题,需要一次设备智能化,二次设备网络化,通过直接采样或网络采样方式,将电子式互感器、合并单元、智能终端、对时技术等有机结合,提高采样精度和信号传输的可靠性。

关 键 词:智能变电站  数字化保护  采样技术  智能终端  对时技术

Abstract:The digital protection of intelligent substation digitalizes the collection, transmission, pro-cessing and output of substation information and share the information within whole substation by layered and distributed communication network transmission. Due to effect of dynamic electromagnetic environ-ment and temperature of the UHV substation, the acquisition circuit is susceptible to interference, seri-ously affecting the sampling process and data synchronization. To solve this problem, intellectualization of primary equipment and networking of secondary equipment are needed. Through direct sampling or net-work sampling, the electronic transformers, the merging units, intelligent terminals, timing technology etc. are combined organically to improve the sampling accuracy and signal transmission reliability.
Keywords:intelligent substation  digital protection  sampling technique  intelligent terminal  time synchronization technology
