Description
The Megger GOOSE Configurator (MGC) provides mapping of the binary inputs and outputs of the SMRT/FREJA test set to the desired GOOSE messages.
The GOOSE messages are read from available SCL (Substation Configuration Language) files or may be automatically detected by scanning the substation network in search of available published GOOSE messages. This scanning process is known as GOOSE “sniffing.”
The MGC also provides advanced network troubleshooting tasks such as comparing the GOOSE messages available on the network with the GOOSE messages described in the SCL files with GOOSE MERGE/COMPARE functionality; this is also a powerful tool for validating the horizontal communication description (GOOSE) in the supplied SCD file at Factory Acceptance Tests (FAT) in IEC 61850 substations.
Frequently Asked Questions
What are the key capabilities of the MGC tool?
The MGC tool enables users to sniff and capture GOOSE messages from the network, essential for network monitoring, troubleshooting. It also allows to configure FREJA and SMRT test sets for GOOSE subscriptions or publications.
What role does MGC play in configuring FREJA/SMRT as IEC 61850 GOOSE publisher or subscriber?
MGC allows users to map GOOSE messages to binary inputs (subscriptions) or outputs (publications) of FREJA/SMRT for receiving/sending (subscribing/publishing) GOOSE messages. It is also possible to map the sending of a GOOSE message to the status of a BI, allowing easy and comfortable simulation of the status of the BI to be sent by the FREJA/SMRT.
What is the significance of the "MERGE" feature in MGC?
The "MERGE" feature compares network captured GOOSE messages with SCL-imported GOOSE messages, helping identify discrepancies between expected and observed messages for effective troubleshooting and configuration validation.
How can MGC validate substation SCD files during Factory Acceptance Tests (FAT) or Site Acceptance Tests (SAT)?
MGC performs SCD file validation by comparing expected GOOSE messages (described on the SCD file) with captured GOOSE messages from the network, highlighting discrepancies that require investigation and correction. This comparison is part of the so-called “Merge” algorithm.
How does MGC manage and manipulate IEC 61850 SIMULATION parameter (IEC 61850 Ed. 2) and the test quality flag in published GOOSE messages?
MGC allows to activate (or deactivate) the IEC 61850 SIMULATION parameters and/or the test flag in the quality string, ensuring compatibility with the simulation and test mode mechanisms described in IEC 61850 Edition 2.
How does MGC enhance the efficiency of network troubleshooting and configuration tasks?
MGC's intuitive interface, network sniffing capabilities, and merging features streamline troubleshooting processes, ensuring reliable substation communication configurations.
How does the MGC address cybersecurity concerns when conducting maintenance activities on live substations, particularly in relation to the potential risks of connecting to operational Ethernet networks?
The MGC addresses cybersecurity concerns during live substation maintenance by using dedicated equipment with embedded software/firmware and a local HMI, enabling non-intrusive testing without direct PC connections to the substation's operational IEC 61850 Ethernet bus. This approach mitigates cybersecurity risks associated with traditional methods that involve direct PC connections. This method, pioneered by Megger as early as 2009, incorporates non-intrusive testing methodologies like GOOSE sniffers to securely detect and validate GOOSE messages, ensuring accurate documentation validation.
Why is it advantageous to have the "MGC on-board" on a straightforward testing device like the SMRT1D?
The advantage lies in the simplicity and clarity it offers during commissioning. When multiple people, tools, and software are in use simultaneously, it can be challenging to track changes in IEC 61850 GOOSE traffic. With a dedicated standalone GOOSE sniffer, always active and monitoring, any unexpected alterations or missing signals can be immediately detected. This real-time insight into GOOSE messages is crucial for commissioning and troubleshooting, as it is recognized by the long on Megger's experience in this field.
What can Megger offer when it comes to test solutions for MMS?
As of now, Megger doesn't offer an "MMS testing tool." For MMS testing, we recommend tools from companies specializing in SCADA and RTU systems, as they understand MMS complexity and can provide non-disruptive solutions for IEDs thanks to their long experience in providing SCADA systems and tools.
What can Megger do for fixed installation testing tools for IEC 61850?
Megger aims to offer 24/7 IEC 61850 testing devices once compliance with the tough IEC 61850-3 is achieved for hardware and EMC requirements (Communication networks and systems for power utility automation - Part 3: General requirements). Meeting these requirements is crucial and it's uncertain if many devices on the market currently fulfil them. Meanwhile, it's advisable to check if suppliers have considered these specifications in their procurement requirements, to avoid that they install non-compliant IEC 61850-3 devices in their substations.
