- Abstract
In this paper, a method for estimating the system harmonic impedance and harmonic emission level based on the pan-normal impedance cloud is presented. First of all, based on the basic principle of fluctuation method, it can be obtained that the key to estimate the system harmonic impedance is how to identify fluctuation ratio samples closer to the true value through theoretical analysis; Secondly, through the study of the probability distribution of fluctuation ratio, this paper proposes the characteristic of the pan-normal distribution meets the applicable conditions of normal cloud model, which can be used to calculate the digital features of impedance cloud by backward cloud generator; Finally, based on the “3En' Rules” of cloud model, the filtering threshold of impedance is determined, then the system harmonic impedance and harmonic emission level can be estimated by filtering qualified samples. It proves the accuracy and effectiveness of the proposed method by the simulation of theoretical model and calculation of practical engineering examples.
