Electrical distribution network's failure analysis based on weather conditions

Abstract

The failure detection and response time for failures in electrical distribution networks are key elements for proper power management in distribution companies. The reliability of electrical distribution is strictly related with weather conditions especially in overhead lines. Severe weather conditions can rapidly increase failure rates in distribution networks where company responses for failures may delayed consequently. In this study, electrical distribution network statistics of Beda; Company for Gaziosmanpasa district which contains highest overhead line population in Istanbul are investigated. These statistics are collected from failure management system in Bedas Distribution Company between 2014 and 2016. Especially electrical connector and oxidation failure rates are analyzed for different weather conditions. These statistics are compared with first four months of year 2017 which exhibit severe weather conditions and heavy falls. This study reveals the relationship between different weather conditions and failures in electrical distribution network which can be utilized for predictive management for distribution companies in terms of failure elimination and quick failure response.
