Description
I. INTRODUCTION Reliability of Supply describes the ability of the network to transport energy, possibly free of interruption and meeting the product quality [1]. This work deals with the reliability distribution networks. It is necessary to observe outages and interruptions of electrical energy for retrieving the reliability indicators [2]. A larger database would describe the real condition of the network more accurately. Therefore, it is necessary to merge databases of various distributors and distribution areas. These databases are used for maintenance optimization of electric distribution network devices. II. RELIABILITY OF COMPONENTS The basic reliability data of particular elements may be computed from the database of outages and interruptions stored at the VSB – Technical University of Ostrava. The results include the rates and mean durations of equipment outages. The actual data collection includes outage data from distributors from the Czech Republic and one from the Slovak Republic. We have retrieved data from eight distribution areas. Today database contains more than 400 thousand records (from 2000 to 2016) on voltage levels 110 kV, MV and partially LV. The graphic representation of all distribution regions reliability indices from the above-mentioned data for the 22 kV cable is given in Fig. 1. From the significant differences in particular years it is possible to observe the contribution of our analyses. The divergence of reliability indices is eliminated during long-term observation.
