A data collection scheme for reliability evaluation and assessment-a practical case in Iran

Data collection is an essential element of reliability assessment and many utilities throughout the world have established comprehensive procedures for assessing the performance of their electric power systems. Data collection is also a constituent part of quantitative power system reliability assessment in which system past performance and prediction of future performance are evaluated. This paper presents an overview of the Iran electric power system data collection scheme and the procedure to its reliability analysis. The scheme contains both equipment reliability data collection procedure and structure of reliability assessment. The former constitutes generation, transmission and distribution equipment data. The latter contains past performance and predictive future performance of the Iran power system. The benefits of this powerful data base within an environment of change and uncertainty will help utilities to keep down cost, while meeting the multiple challenges of providing high degrees of reliability and power quality of electrical energy.
