Abstract :
Methods of determination of the first and the second order moments of stochastic processes for a three phase system have been given in the paper. Stochastic processes observed in the system could be a result of stochastic nature of the source or the load. A few cases have been considered including stochastic voltage and current waveforms with deterministic components as well as deterministic voltage and stochastic current waveforms. It has been assumed that stochastic processes in the system are of the second order or they can be described precisely enough by the first and the second order moments.
