Sažetak
The relationship between reliability and daily load curve is presented in CIRED 2009 paper. The beginning moment of unplanned (forced) interruption occurs stochastically. Also, reliability has dynamic (fluctuating) nature during daily hours. For observing this phenomenon additional indicators like three-hourly (3-h) SAIFI and SAIDI where used. Now, input data have been collected for three years from real network and the results confirm the first assumptions. 3-h SAIFI is giving strong relationship between reliability and load variation and 3-h SAIDI value is correlated with heaviness of interruption, maintenance controlling and development policies. It became obvious that probability of interruption with more difficult consequences is higher within heavily loaded network than during light load regimes. At least, the 3-h CAIDI was and could be useful for this research too. Knowledge on daily fluctuation of electric distribution reliability can have positive impact on maintenance strategy, distribution network development and power system control. This paper presents the analysis of reliability value fluctuations during the day using real three years data set taken out from the real power network, with the aim to help to improve reliability indices and final customer satisfaction.
