IEC 61850 specifies communication protocols for intelligent electronic devices (IEDs) operating at digital substations.
When integrated with COPA-DATA’s zenon software platform, this standard has the transformative potential to streamline and fortify energy automation systems. This harmonious integration enables unparalleled operational data transparency, ensuring robust system interoperability and real-time, reliable control. Designed for flexibility and scalability, the IEC 61850 and zenon synergy unlocks efficiency in power system management, offering an elevated level of sophistication in handling complex energy networks.
Whether in grid automation or substation management, this partnership promises to enhance performance while adhering to global compliance requirements, setting the stage for a new era of energy distribution intelligence.
The high level of risk present in the pharmaceutical industry has made many manufacturers hesitant to move away from paper documentation and embrace the total digitalization of the manufacturing plant. As drug patents expire, however, production efficiency becomes increasingly important. At COPA-DATA, we have developed our pharmaceutical manufacturing software zenon to help companies overcome industry challenges and optimize their processes using innovative technology.
Future-proofing utility operations with digital substation technology
The digital substation market is expected to grow by over 7.3% from 2022 to 2028, driven by the benefits of more accurate and reliable data, faster response times, and cost savings on property and infrastructure. However, transitioning from traditional to digital substations can be challenging due to end-user reluctance and limited know-how. COPA-DATA's zenon Energy Edition offers an HMI solution to enable smarter and interconnected substations, resulting in time savings, reduced workload, and a lower risk of errors. Effective staff training and innovation in testing protection relays are critical to addressing these challenges.
In this article, we examine the advantages that IEC 61850 provides for utility companies, with a particular emphasis on its capacity to optimize operations, interoperability, flexibility, and efficiency with zenon. We focus on the capacity of the standard and how it enhances grid management, decision-making, and data exchange. Additionally, we also underline how this standard underscores its capabilities in zenon to adjust to evolving demands, thereby circumventing expensive retrofitting procedures via investment security of the zenon software platform. Furthermore, we emphasize the role of the standard in monitoring, controlling, and automating power systems, which contributes to decreased outage, enhanced asset management, and improved reliability to facilitate smart grid functionalities and advanced applications, thereby establishing a pathway towards a more resilient and sustainable energy future.

Local and Remote Operations of Digital Substations
Powerful solutions enabled with zenon in Digital Substations
The zenon Software Platform builds the foundation to realize a number of innovative tasks and solutions in digital substations:
Substation Gateway
Central monitoring via regional or national control rooms is a major requirement in many projects. zenon enables this feature with its integrated process gateway. All relevant protocols, such as IEC 60870, DNP3, IEC 61850, MODBUS or OPC UA and many more are available. The connection allows to fully monitor and consistently control substation equipment. For this purpose, the gateway software can mediate flexibly between control center and substation devices, even in case that different protocols are being utilized.
GOOSE Communication Monitoring and Substitution
It may seem unusual for an HMI/SCADA package to come with IEC 61850 GOOSE protocol support. However, it opens a wealth of possibilities. With a GOOSE subscriber, GOOSE messages can be monitored and supervised, leading to better availability and more confidence in this new technology. To replace missing GOOSE messages - for example due to component failure - the GOOSE Publisher can be used. This allows GOOSE messages to continue to be made available until the component failure is resolved.
High availability networking with PRP
PRP (Parallel Redundancy Protocol) is an industry standard which provides seamless failover against any failure of any network component. All Ethernet based communication protocols in zenon, such as IEC 61850 MMS Client and Server, as well as GOOSE can be utilized on basis of PRP.
Unified management of disturbance records
High precision oscillography and status data is captured by IEDs and protection equipment and stored into so called disturbance records. Via the so called File Transfer function, zenon collects these files from the network of IEDs, making them available for central investigation with expert systems. Moreover, zenon is equipped with an integrated COMTRADE viewer (Common format for Transient Data Exchange for power systems), which allows to directly visualize disturbance records according to IEEE C37.111 in the local HMI.
Commissioning support (FAT/SAT)
During FAT and SAT (Factory and Site Acceptance Testing), plant components or devices are often missing. To simulate these, zenon offers extensive tools to create virtual processes. So at least the existing part can be pretested in combination of the simulated part. For the SAT further functions are needed like the variable diagnostic list, which gives a filterable overview of all communicating data points. In addition, the system screen (coms-screen) provides information about the connection status of the connected devices. For the trial operation, alarm statistics can help to find the hotspots of necessary rework.
Device exchange and equipment validation
During regular operation, protection devices must be validated in regular time intervals. In classical, hard-wired plants, this has been a labor intensive procedure. In fully digitalized substations with Process Bus according to IEC 61850, however, dedicated functions can be used in order to perform in-system tests, without the need of physical intervention. Here, zenon can help to clearly indicate the operating mode of the plant and it´s components. By interpreting the IEC 61850 information, the test engineer can transparently identify which parts of the plant are isolated or in test mode. zenon helps to reset all relevant settings consistently and to re-arm the protection devices, once the tests have been finished.
Moreover, defective substation equipment needs to be replaced fast and must be thoroughly tested before switching back to regular operation. zenon offers solutions for a quick replacement of an IED in case of a breakdown. With the use of an alternative datapoint driver, values can be instantly routed to a replacement device, regardless of type and model.
Benefits for a highly-efficient engineering workflow
MMS Client – Data acquisition from IEDs
The IEC 61850 MMS Client driver comes with exceptional feature support and compliance to the standard. It supports Edition 1 as well as Edition 2.1 of IEC 61850-8-1 and is continuously enhanced according to the evolution of the standard. It is possible to upload data models from IEC 61850 servers as well as adopt them from SCL-files. Configuring the MMS client is done with the help of clearly structured dialogs which allows to adjust every aspect of the drivers functionality. Templates and automatic configuration tools can be utilized for large and standardized systems.
The driver supports static, as well as dynamic datasets for Reporting. In addition, special attention is paid to redundant HMI systems in terms of reports, so that continuous operation is guaranteed, even if a system part should fail. All in all, zenon´s IEC 61850 MMS Client helps the engineer to proceed with ease through bottom-up scenarios, but also promotes the realization of efficient top-down engineering workflows.
MMS Server – Providing data and services to higher level clients
An integrated IEC 61850 MMS server in an HMI can be utilized in various ways. It can be used for data aggregation, unification of communication, as a gateway or as a simulation and test utility. To achieve maximum flexibility, the IEC 61850 MMS server is integrated into the IEC 61131-3 (Soft PLC) environment of zenon. Thus, it is possible to adapt individually to an infinite number of configuration possibilities. Nevertheless, the basic rules of model description are also applied here. To start setting up the MMS Server´s data model an external SCL file can be imported. The entire data model and advanced server configurations are arranged with the help of an integrated configuration tool.
