The superposition of the random harmonic phasors based on the cloud model

A novel method based on the cloud model for the superposition of the distributed random power harmonics is presented in this paper. Three characteristic quantities (E_x, E_n and H_e) of the measured harmonic phasors are calculated by the cloud model inverse generator. The probability density function described by the cloud model is presented to obtain the 95% probability value of the harmonics. Field tests results prove that the presented method has a good performance even with small volume of samples, which does not need the particular probability distribution of each random phasor.
