【摘要】：智能变电站采用光以太网GOOSE报文和SMV报文实现开关量信号和交流模拟量信号的传输,用网络报文数据流代替了传统变电站内的电缆硬接点信号。基于IEC61850标准的智能变电站在实现方式和应用方式上都有较大变化,智能变电站控制回路、信号回路和采样回路等都采用网络通信报文的方式实现,其实现和应用技术难度远大于传统变电站。在智能变电站内,当系统发生故障时,除了需要对网络原始报文进行记录,还需要将网络报文进行解析,还原为对电力系统一次设备故障波形以及二次设备动作行为的记录,便于事故发生后进行分析和快速查找故障原因。因此,为了满足智能变电站运行、维护的需求,将报文分析记录和故障录波两种功能一体化设计,构造网络报文记录与暂态故障故障录波一体化系统。本文对智能变电站FT3(IEC60044-8)(?)文、IEC61850-9-2报文、GOOSE报文进行研究；确定各种网络报文数据采集方案；总结归纳过程层通信中可能出现的各种异常情况；分析报文检索方面的需求,提出网络报文预处理要求以及存储算法和处理策略。利用计算机技术、网络通讯技术、软件技术和数据库技术,建立先进的录波报文记录分析平台,形成一个集数据存储、传输、分析等多种功能相结合的有机整体,实现报文分析功能,实现异常报文的处理和显示实现对SAV采样点报文和GOOSE开关量报文的提取功能。该网络报文记录与故障录波一体化系统为智能变电站的调试和检修提供了技术支持,对智能变电站安全稳定可靠运行打下坚实基础。
