智能变电站故障录波系统设计与探索

Design of intelligent substation fault recorder

智能变电站故障录波系统是针对当前智能电网的发展而设计开发的故障录波分析系统。系统可接入智能变电站过程层网络的IEC61850-9-1或IEC61850-9-2模拟量采样值(SMV)报文和IEC61850-8-1面向变电站事件的通用对象(GOOSE)报文,并将GOOSE解析成实际的开关状态,并且系统也支持SMV+GOOSE共网模式,直接从交换机获取SMV和GOOSE。系统与站控层设备的通信采用IEC61850制造报文规范(MMS ISO 9506)通信规约,实现与站控层设备的互操作。系统采用嵌入式POWERPC硬件平台和嵌入式实时多任务VxWorks操作系统,满足了当前智能变电站对故障录波器提出的新要求。

The intelligent substation fault recorder is designed for the development of smart grid.The system supports the IEC6185091 or IEC61850-92 SMV（Sampled Analogue Value） packets of substation process networks and the IEC61850-8-1 GOOSE（Generic Object Oriented Substation Event） packets,which are parsed into switch status.It also supports SMV＋GOOSE coexistence mode,directly acquiring them from the exchanger.It communicates with substation control lay devices using IEC61850 MMS （Manufacturing Message Specification） to realize the inter-operation.The embedded POWERPC hardware system and VxWorks realtime operating system are adopted,meeting the new requirements of intelligent substation.
