Harmonic Interaction in Capacitor Rectifier Loads

In this paper a steady-state model of a single-phase power supply is presented, The model takes into account the influence of feeder harmonic voltages on the non-linear load behaviour. With this model we can observe that, when the distorting load consumption is important, the harmonic interaction must be considered in order to obtain correct results. This model has been implemented in a harmonic load-flow program in order to perform harmonic studies in network and industrial installation.
