Abstract In many power substations, we need to transfer Modbus measurements like volts, currents, frequencies, and powers from the high or medium voltage levels to the station level as IEC61850 standard. There are some devices that support some protocols like Modbus, EtherCAT, IEC104, etc which are not compatible with the IEC61850. So, we need to automate and integrate the Modbus with the IEC61850 standard into one entity or physical device to automatically send alarm points to the IEC61850 client or Human Machine Interface (HMI). This occurred in case of a defect in measurements by the Modbus slaves to manage the operation engineers who work in the power substations monitor all the Modbus registers values into the screens. This thesis discusses integrating a configuration tool for physical devices with a run-time tool into a physical entity to perform Modbus to Message Manufacturing Specification (MMS) mapping and create the dedicated Intelligent Electronic Device (IED) configuration file. Configuration Tool dispenses with creating the preconfigured mapping associated file, device description file, and IED configuration file by an external tool. This configuration tool facilitates the automation engineer to configure the specific registers for any Modbus device without obligating him to use all this device’s registers. The configuration tool facilitates the automation engineer to map those Modbus registers to the IEC61850 standard, it eases for him to create the IED configuration file according to the mapped points. The Run-time tool dispenses with the database for achieving the mapping between the Modbus and the IEC61850 after getting the Modbus response to send the mapped IEC61850 to the HMI at the station level. This tool uses the created IED configuration file that is created by the configuration tool to create the model nodes for the IEC61850 and map the Modbus data points to the model nodes then send the Modbus registers values with the model node to the station level or HMI for the operation engineer. |
