Power Components Analysis under Non-Sinusoidal Conditions

The power components analysis under nonsinusoidal conditions is presented in the paper. The main idea of such analysis is to model and simulate the different ways of nonsinusoidal conditions forming. The main ways of non-sinusoidal conditions forming are considered and analyzed. The components of the apparent power under non-sinusoidal conditions are detected and evaluated for an each way of nonsinusoidal conditions forming. During modeling and simulation the parameters of power source and connected load varied in given ranges. The results of modeling and simulation of nonsinusoidal conditions forming should be considered as a basis for the further selection of harmonic elimination methods. The obtained values of total apparent power components help to detect the primary cause of non-sinusoidal conditions forming in centralized, distributed and combined power supply systems with nonlinear load.
