In 2008, Fingrid launched a project, the aim of which was to build a new information system that supported asset and operation management and was based on product-based solutions. This new data system that supports asset and operation management goes by the name of ELVIS (an acronym for ELectricity Verkko Information System).

Editor's Notes
- Name and what I have done in the project Achieved, feedback and synergy in development on the same interfaces, challenges it's possible to fully integrate IT processes of asset management, long term planning, operational planning, protection This might seem very specific to Electricity TSO world, but there are plenty of learning points for other industries as well: big data, placing everything on location, master data, standards
- You are probably well saturated with information and looking forward to dinner, but before that I want you to focus on one important topic that probably. - situation awarness and making decisions For example in Control center tha normal view to the situation in the grid is a schematic diagram with flows and alerts in separate table format with diffent colour coding. Heat map Not only the vsualization, but the most important thing which is that - decisions are made based on the correct (common information) independent on if we are talking about safety, reliability or money
- Not talking about how we do planning, but Grid model, CIM based integration long term planning, asset maintenance, operational planning, protection
- grid services = schematics that show the connecting customers grid operator in the control centre = scada view with real time measurements and all the primary equipment long term planning = schematics with just one bus representing a voltage level at substation protection = the current transformers and secondary equipment connected why to integrate: less mistakes in manual copy motivation benefits in drilling in to information and background, knowledge of where the information is used. That it is IMPORTANT to keep things up to date.
- The GIS Powergrid model is a CIM adaption, but must still first and foremost serve as a GIS network model. By contrast, ODMS is a pure CIM-based system. Thus, mapping of the connectivity model is a necessity. Particular complex details include: Mapping of switches from a point feature into a two-terminal device. The necessity of creating abstract elements (Terminals and some ConnectivityNodes) out of a more crude model.
- Planning GIS and ODMS Maintenance Maximo and GIS Operations Maximo and ODMS
- ODMS functions as the bridge between the node/breaker operational model and the bus/branch planning model. The mapping is bi-directional. The backwards mapping is used to represent calculation results in ArcGIS and Maximo.

- It's possible to do manually, but with integration you know that the results that you use for decision making are based on the master data. Examples of integrated calculations in ELVIS
- before done in excel and results were Analysis based on Asset data and measurements (Maximo) CIM grid model (ODMS) Relay Actions on fault (trip time) at each tower (CAPE) Results available on map at each tower (Maximo Spatial)
- Asset data (Maximo) Topology of primary equipment (ODMS)
- Realtime measurements (PI) Temperature dependent ratings (Maximo)
- Common grid model which is synchronized with asset management, operations planning, long term planning and network protection analysis All switch gear modeled with real and accurate description of components in the grid. Lot's of additional information about the grid model. Accurate planning grid model linked to real time status and metering data. Preparing of calculation model is easy by using status and metering data from the past Attributes for grid components available through the map Visualization of real time power and voltage measurements using colours on grid model or map Common database about future projects where schedules are in sync through the systems Easy to build different scenarios
- - How do you handle possible issues with data quality at the source of data? - good communications between linked processes, error checking scripts, interface error handling, out of box data quality checking - Have you faced challenges with using CIM grid model database instead of the previous taylor made grid model database? - CIM presents the grid in a format that no-one has been used to so most important is changge management and focusing on the benefits. Still I do hope to see development in thee programs for better visualisation of data for example transformer electrical values shown in a "normal" nameplate format with per unit values instead of the SI standards format.
