    • Disclosed is a fault diagnosis device for diagnosing a fault in a bay Intelligent Electronic Device (IED) for a substation automation system, which includes an online IED diagnosis device and a backup IED. The online IED diagnosis device includes an IED selection unit, an IED switch unit, a fault diagnosis, and a result display unit. With reference to a Substation Configuration Description (SCD) file, the online IED diagnosis device designates an IED to be tested, and extracts backup information for the IED to be tested. A backup IED replaces the operation of the IED to be tested based on the extracted backup information. Further, the online IED diagnosis device determines the occurrence or non-occurrence of a fault in the IED to be tested by analyzing response information received in response to transmission of a test pattern to the IED to be tested.
    • 公开了用于诊断用于变电站自动化系统的托架智能电子设备(IED)中的故障的故障诊断装置,其包括在线IED诊断装置和备用IED。 在线IED诊断装置包括IED选择单元,IED开关单元,故障诊断和结果显示单元。 参考变电站配置说明(SCD)文件,在线IED诊断设备指定要测试的IED,并提取要测试的IED的备份信息。 备份IED根据提取的备份信息替换要测试的IED的操作。 此外,在线IED诊断装置通过分析响应于测试模式的发送而接收到的响应信息,来测试待测IED中的故障的发生或不发生。
