摘要：This paper presents a definition of "total harmonic contributions". In order to calculate the harmonic voltage instantaneous value at the point of common coupling (PCC) produced by harmonic source's harmonic current, a time domain equivalent model of distribution network is established. What's more, a computational method about total harmonic contributions determination is deduced in this paper. Based on the covariance characteristic of random variables, equivalent parameters of utility-side can be obtained. On this basis, the total harmonic contributions of harmonic source at the PCC can be calculated. At last, based on the platform of LabVIEW, a prototype is constructed to determine harmonic source's total harmonic contributions. The stimulation experiment has testified the validity of this method proposed in this paper.
