A new method for power factor correction and harmonic elimination in power systems

The influence of power electronics-based technology, which is increasingly used, has a disadvantageous effect on the quality of electric power supply. Pure sinusoidal voltage supply no longer exists. Low and medium voltage power systems are polluted to an increasing extent by harmonic currents and voltages, voltage fluctuation, voltage unbalance, voltage sags, voltage swells and flicker. This paper presents an new configuration for power factor correction and harmonic current elimination in electrical power systems. A single-phase control concept is discussed for simplicity. It also presents a brief discussion of the main problems in power distribution systems.
