Analysis of inverter models and harmonic propagation. Part II. Harmonic propagation
Part II of a three part study describes the harmonic propagation in the photovoltaic power system consisting of the solar cell array, the inverter, and the ac side of the inverter up to the infinite bus of the utility. Propagation of the harmonics in the utility system are not addressed. Two main problems are analyzed: power in the converter system and harmonics of the current and voltage waveforms of the single-phase, dependent inverter. Relationships between the different components of the converter power - active, reactive and disturbance - are discussed. All formulas necessary for calculating the power components are given, assuming the harmonics of the current and voltage waveforms are known. The theoretical and experimental investigation of the single-phase, dependent inverter is described. The ac and dc terminal voltage of the inverter are analyzed and their harmonics are obtained. These data determine the harmonic propagation on both the dc and ac sides and may be useful for equipment design. Part I of the study (SAND 7040/1) contains a detailed description of the microcomputer based simulator that represents the output characteristics of the five commercially available types of solar cell arrays under different environmental conditions, and Part III (SAND 7040/3) presents an analysis of the transient and steady-state processes of inverter modules.
