Pseudorandom number generators as applied in reliability analysis

: An electric power system is damaged mainly due to random factors. In this case, computer methods that allow simulation of phenomena occurring in the system are very helpful. These methods, along with the development of computer techniques, have become an increasingly used research tool. In order to properly model the operation of the electric power system elements, it is necessary to map the distributions of the reliability function and the renewal function of individual elements. The probability distributions of the correct operation time or the failure duration of the components can be modelled using selected pseudorandom number generators. The article presents and tests the distribution generators most often used in reliability analyses of electric power systems, and which are considered the standard - normal distribution, Weibull distribution, exponential distribution and log-normal distribution .
