FASIT, the Norwegian reliability data collection system - experiences and utilitarian values


FASIT has been in operation since 1995 and has since then been regularly updated. A major revision and update with an information model based on CIM and utilizing the MADES/ECP communication technology resulted in a new version put into operation from 2019. All messages and grid incident reports are exchanged encrypted machineto- machine, thus reducing manual work, and securing data consistency between the different modules in the system. The paper focuses on the areas of use, the applications, and the utilitarian values for the NRA and the TSO in their supervision and control, for the DNOs in using the collected data to improve their own performance, and as a source for input data for various reliability calculations and simulations. The main source of information is each DNO's inhouse FASIT database, together with the nationwide PQ Portal, which is a fault and interruption statistics generation tool where users can select/filter data from the national database to get statistics best suited for the analysis at hand, or to benchmark their own company towards comparable companies or the Norwegian average.
