Study on the Superposing Methods of Multi Harmonic Wave Source Based on the MATLAIB Power Supply System

Aiming at multi-harmonic wave source in power supply system, the wave-superposing problem should be considered. Under the corresponding suppositions, this paper puts forward to use the central limit theorem to compute the superposition of harmonic wave currents of multi-harmonic wave sources. At the same time, the characteristic of probability of harmonic wave current can be obtained. The rationality and reliability of this method can be demonstrated by comparing it with the Monte-Carlo simulation.
