Evaluation of customer orientated indices and reliability study of electrical feeder system

Aim. Reliability evaluation of a system or component element is very important in order to predict its availability and other relevant indices. the parameter which tells about under proper working conditions for given period time. The study different reliability indices are considering complex uncertain nature power system. Methods. uses classical methods theory respect with constant failure rate consisting series-connected elements. Conclusions. paper reviews literature dedicated estimation supply systems. In particular, examined studies that employed Markov cut-set approach, conditional probability distribution systems simulation, probabilistic models, Monte Carlo method, network equivalent, state transition sampling, inspection repair-based optimisation systems, bootstrapping, fault tree analysis, Bayes networks, peak-valley partition model, demand response etc. authors defined problem analysed input data. They showed that, physical terms, configuration will be series network. Given above, fails even if one fails, survives all components survive. It noted when three basic parameters average rate, annual outage time repair As customer orientated associated research operational interruption frequency index (SAIFI), duration (SAIDI) (CAIDI) were used. Using example an eight-node radial system, was estimated each section, as well, at load point. For sections points, also obtained, i.e., customer-oriented estimated, index, index. resultant data allow characterizing indices,
