Perspective Chapter: Frequency Domain Models of Nonlinear Loads in Power Systems

Abstract

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.
