Improvement of supply quality in distribution systems

The growing number of low-pulse power electronic loads in distribution networks causes an increasing line voltage distortion. At the same time a large portion of consumers are sensitive to deviations of the line voltage from its ideal sinusoidal waveform, which can also result from network faults or unbalanced loading. This paper describes the main power quality problems in distribution systems and ways of solving them by utilizing state of the art power electronic equipment, the so called power conditioner.
