基于虚拟建模技术的直流输电故障录波智能网关设计

Design of the smart gateway of HVDC fault recording system based on virtual modeling

基于虚拟建模技术的直流输电故障录波智能网关,将换流站内所有录波装置建模成录波逻辑设备,即建模成虚拟的智能电子装置(IED)模型,实时侦测所有录波装置的故障录波数据区生成的文件,并生成重定向文件,同时驱动录波逻辑设备,采用IEC 61850通信协议并扩展文件访问服务,实现与调度中心智能录波主站系统的通信,可以解决直流输电故障录波系统启动频繁、录波文件数量庞大的问题。

The HVDC transmission fault recording smart gateway based on virtual modeling technology models all wave recording devices in the converter station as wave recording logic devices,detects the files generated in the fault recording data area of all wave recording devices in real time,generates redirect files,drives the wave recording logic devices,adopts IEC 61850 communication protocol and expands file access services to achieve communication with the intelligent wave recording master station of the dispatching center.It can solve the problems of frequent startup of HVDC transmission fault recording system and huge number of recording files.
