Abstract

This paper presents statistical description of the magnitude of the sum of injected harmonic currents produced by multiple AC drive with randomly fluctuating loads using bivariate normal distribution (BND) method. The effects of motors speeds and input line reactance variations upon the probabilistic behavior of the magnitude of the vectorial sum of random harmonic vectors are investigated. Monte Carlo simulation is performed to justify the obtained results
