Reliability database of industrial local distribution system

Abstract

Calculatin of the supply reliability is impossible without trustworthy input parameters. It is possible to find reliability indices of electricity transmission or distribution system but there is hardly any of local distribution system at heavy industry. The paper shows the way how to get reliable results—collection and processing of information and documentation from the dispatcher logs on the operation of the local distribution system within the premises of an industrial plant. The first part focuses on development of equipment passportization and processing of documentation for system operation. Additionally, the work deals with calculation of reliability indices of overhead lines and components. The final part brings the comparison of reliability indices of the input overhead lines of the industrial local distribution system with overhead lines of the distribution system of the Czech Republic.
