Abstract

Nonlinear elements connected to power systems cause harmonic currents in them. Even though the source voltage of nonlinear elements is sinusoidal, their currents are nonsinusoidal. Nonsinusoidal currents include harmonic components which can be obtained by Fourier analysis. Nonlinear elements such as converters, gas discharge, lighting, arc furnaces, and VAr compensators also have nonlinear current-voltage characteristics. Harmonics produce some negative effects. It is necessary to research and remove the unwanted effects of harmonics for which harmonic components must be computed. In this paper, a 6-bus power system including the nonlinear loads is considered and the harmonic power flow is achieved in the system. The effects of the shunt elements (reactors and capacitors) on the harmonic power flow are researched
