A Pre-Study Towards Investigating the Art of Choosing Right Level of Input Data

Abstract

Abstract-The international tendency towards quality regulation of power distribution tariffs, along with a generally increased pressure of cost efficiency with maintained high reliability, give incentives to introduce more advanced analysis methods within asset management and project planning. This paper proposes a method to compare existing analysis methods with other methods or improvements of current method without perform any sharp changes in the organization. The approach is to compare recently performed risk reducing investments, based on current analysis methods used by the company, and then perform a hypothetical investment planning process based on more comprehensive reliability analysis. This paper presents results from a pre-study of a collaborative project between the industry and the academy to highlight and investigate the art of choosing right detail level of input data used within reliability analysis of power distribution. The aim of the paper is also to: on one hand provide academic reference material from the "reality", and on the other hand to inspire the industry to review their current analysis methods and if needed, implement improvements
