FEASIBILITY ANALYSIS OF THE PROBABILISTIC MODELLING OF LCC BASED HVDC EQUIPMENT AGEING USING PUBLIC DATA

Abstract

A component's risk of failure increases with age. Therefore for the design of effective, risk based maintenance policies the ageing rate of the system and their constituting components must be considered. However chronologically ordered failure data is seldom publicly available. This paper explores the possibility of using publicly available empirical failure data to construct probabilistic reliability indicators for the main components of line-commutated-converter (LCC) based HVDC systems.
