Application of a random number generator for calculations of the trolley mains dimensioning

A generator of random numbers can be used in a calculation wherever a constant is used in a mathematical equation, for which changes of numerical values within a specific range can be determined on the base of an empirical research. This way a random change of a numerical value of one or more values influencing parameters of an electrical circuit can be expressed mathematically at the same time. A presupposition for a simulation of more values in a circuit is the use of a corresponding number of independent generators of numbers with a specific range of values. This paper deals with the use of a generator of random numbers for a peak load constant with a follow-up statistical evaluation of resulting values. For this purpose a stochastic algorithm has been developed in the Delphi development environment.
