Common guidelines for reliability data collection in Scandinavia

Abstract

The paper presents a work that has been carried out in a common Scandinavian research project. The aim of the work was to establish common guidelines in Scandinavia for fault reporting, and to prepare the foundation for a Scandinavian fault database for voltage levels above 1 kV. The Nordel guidelines for reporting of disturbances above 100 kV are the most important basis for this work. The paper also discusses how users of a future database can be given access to the fault reports through the internet. The long-term goal of utilising component information in addition to the corresponding fault data through an internet database is also pointed out.

FASIT - a tool for collection, calculation and reporting of reliability data

“…A growing interest from regulators around the world towards regulating quality of supply increases the need for harmonised and standardised statistics to perform benchmarking and to monitor trends. In the Nordic countries there has been a cooperation on the transmission level for many years to standardise fault statistics and there is work going on to standardise the collection and reporting on the distribution level as well [8,9]. This is an important basis for the future development of FASIT.…”
