Abstract
The IEC 61850 series of standards is widely used to build power utility automation systems. The configuration process is well established and proven, based on standard file exchanges, with definition of information models, services, and mappings over a standard communication interface. This made the vision of a truly multi-vendor power utility automation solution possible. The interoperability is provided not only at data exchange level, but also at semantic and engineering level. But it is still tightly coupled with the way these functions are implemented in a real IEDs. Next step of interoperability shall be at early stage of the system engineering, to specify the requirements in a standard way, in an implementation-agnostic way. IEC 61850 standard already defines such specification capability in a standard format but only for the electrical process description. It is now required to also be able to start to describe the automation applications on top of those process functions. The European project H2020 Osmose task 7.1 is working on improvement of the specification process to provide such capability [1], and the result is directly reused by the IEC Technical Committee 57 to write the new standard part IEC 61850-6-100 [2]. This standard will propose different evolutions. Among them there is the capability to describe data exchange requirement between functions without any details on how they will be implemented on the IEDs. This paper will present the possibilities offered by these evolutions and how the engineering process will evolve into a more user requirement centric approach, earlier in engineering stage to have a better top-down system engineering process, with reusable artefacts between projects, and an increase the quality all along the process down to commissioning stage.
