IPS: Integrated IED asset management, risk management and maintenance strategies

Več…

Throughout the World we face the same initial question when talking about integrating/implementing a new protection setting management system. It is about where to take the initial information from. Which data silos, … the network model(s), a setting calculation and coordination tool, enterprise resource planning system or file structure with questionable data validity, … will be used as the quasi “single source of truth”? Only in rare cases there is a clear answer and usually we start integration process with joining and mapping data from several systems to one centralized IED configuration management system and Wide Area Protection Coordination system. This is far from the concept how the modern data organization in power utilities should be.

The information that needs to take a strong role as a source in initial substation data definition is expected to come from IEC61850 and corresponding substation design data. IEC61850 harmonization with CIM standard and network model management needs to be defined in near future to allow the end user to enter all important substation data into network model management / asset management system with minimum effort.

The paper will describe the process / roadmap of the consolidated secondary station equipment data management, integration of protection data to network model and to Wide Area Protection Coordination (WAPC) system, setting change process, risk management and maintenance / refurbishment coordination. Paper will also show an example how to manage protection scheme diagrams on up to date and flexible ways, following actual IED configuration and not only attaching a PDF document as it is used in today’s practice.
