Section 1 deals with harmonic current sources models for one diode and two diodes rectifiers, the model parameters being determined by simulations. Section 2 describes frequency domain (FD) models of nonlinear home appliances whose parameters are determined by measurements. Some FD models for the loads using firing angle control devices are presented in Section 3. The fourth section presents the simulations of a relatively large circuit in the time domain (TD) and in the FD using the algorithms of CADENCE and ADS. The HB analysis of ADS using the proposed FD models proves to be the most efficient for this example.

“…The computational effort is huge. The reduction of the computational burden proposed in [14,[16][17][18][19][20] can be implemented by only retaining the first and most significant harmonics at the terminals of the nonlinear elements, which can be obtained through measurement. Behavioral frequency-domain models can be computed based on these nonlinear voltage-current relationship measurements.…”

The present paper is devoted to applying the Hănțilă method for solving nonlinear three-phase circuits characterized by different reactance values on the three sequences (positive, negative and zero). Nonlinear elements, which are components of the circuit, are substituted by real voltage or current sources, whose values are an iteratively corrected function of the voltage across or the current through them, respectively. The analysis is carried out in the frequency domain and facilitates an easy evaluation of the power transfer on each harmonic. The paper presents numerical implementations of the method for two case studies. For validation, the results are compared against those obtained using the software LTspice in the time domain. Finally, the power flow on the harmonics and the overall power balance are analyzed.
