Electrical power systems’ evolution toward a smart grid is spurring the growth of network automation on all voltage levels. The IEC 61850 standard is quickly emerging as the choice for designing power utility automation systems.
As such, the scope of the standard has widened from pure substations to all automation aspects of the domains of power generation, transmission, and distribution, including distributed generation. All other legacy protocols also allow protection, control, and measurement functions.
IEC 61850’s value is not limited to communication mapping. It includes support to accommodate business-related semantic models, which allows power system equipment modeling, associated smart functions, and related global information exchange, as well as sufficient flexibility for undertaking new demands as shown by the recent shift toward the smart grid. The standard’s evolution requires the transformation of engineering tools to meet new challenges with a focus on two issues: interoperability and performance estimation.
Interoperability, the idea that intelligent electronic devices (IEDs) from different manufacturers can exchange information and work together in a system, is an important aspect of IED and system engineering and a central goal of IEC 61850. Interoperability is a key consideration in order to enable the proper performance of a given automation solution in a multi-vendor system. Further, the subject of performance estimation is important because it provides early insights into the feasibility of the performance of a given solution and thus reduces risk — technical and contractual — in a multi-vendor environment.
Data analytics play a large role by helping users discover meaningful patterns in data and by transforming data into insight for better decision making. By creating, incorporating, and enforcing a rule-driven system specification for analytics, system integrators can, for example, design rules for a specific project context for later use during the project design phase. Essentially, these rules will teach software to automatically respond to particular situations, controlling risk and increasing efficiency.
The primary role of rule-based analytics in an IEC 61850 setting is to detect non-interoperability between IEDs and to estimate system design performance. Analytics can reduce non-interoperability risks by emphasizing the specification of a given system function, which will improve early detection of non-interoperable behavior and allow for correction. Performance estimation analytics enable the creation of performance profiles of the multitude of IEDs That provides visibility over a product’s life cycle and applicability of a given group of product to design a given automation solution.
Forward-looking utilities, industrial grid operators, and system integrators should investigate how they can leverage engineering tools and analytics to reap these benefits.
