3D REPRESENTATION OF OPERATIONAL AVAILABILITY OF BIHOR POWER SYSTEM EQUIPMENTS.

The paper is part of traditional concerns of Energy Engineering Department from University of Oradea, aiming operational performances identification of equipment of power systems in collaboration with specialists who operates these systems. Based on previous analysis results, existing in databases which are updated yearly and using fundamental reliability indicators, this paper aims to highlight the 3D evolution of equipment operational availability, admitting a random variation of fundamental reliability and maintainability indicators of equipment. After justification of the need of these preoccupations, in the second part of paper, it is presented the mathematical model that stands at the base of 3D representation of operational availability. The third part contains the results referring to EEP from Bihor county PS. In the last part the conclusions are drawn. [ABSTRACT FROM AUTHOR]
