System Engineer Configures IEC Gateway to DNP3 Substation

Transcription

1 1 Description of Function 1.1 Function Name System Configures to DNP3 System Configures to DNP3 1.2 Function ID DNP3-IEC Brief Description Given DNP-XML Device Profiles for a substation automation system consisting of multiple DNP3 devices, a system engineer configures a gateway device so an Client can control and monitor the substation using. 1.4 Narrative <Text narrative still to be added> Key issues include: How are points selected from the DNP devices? Is there an internal DNP3 point map in the gateway that can be used to specify points? Should the final configuration of the gateway be performed using an SCD file, or by updating the DNP-XML files of the various devices? System Configures_IEC_61850 to_dnp doc 1 6/22/2011

Sometimes referred to as the SCADA processor or SCADA system. Device The component in a substation responsible for gathering data from all substation devices, filtering the data as appropriate, and reporting it to the Client of the Energy Management System or Distribution Management System. Contains the Server and DNP3 Master applications. Server Software Application The software within the that communicates with the IEC Client in the control center using. DNP3 Master Software Application The software within the that communicates with IEDs within the substation using DNP3. DNP3 IED Device A device within the substation that communicates with masters and other IEDs using DNP3. System Software Applications Software responsible for configuring the Client in the control center. System Configures_IEC_61850 to_dnp doc 2 6/22/2011
