Abstract

When nonlinear loads are put into operation at random phase angle in power system, the superposition of harmonics should be considered. Based on the characteristics of multi-harmonic source, this paper raised the central limit theorem to compute the superposition of harmonics currents of multi-harmonics sources. At the same time, the characteristic of probability statistic on the same order harmonics will be provided. It is proved that this method provided in the paper is feasible comparable to the Monte-Carlo simulation
