The static var generator (SVG) with appropriate control method is a good solution to solve the problem of reactive power impact and harmonic pollution which is generated by the nonlinear load. A control strategy using active current separation and the current indirect control is used for SVG. The active current separation is a method for detecting the harmonic and reactive current, and then the su...

Power factor is the percentage of consumed power(KW) versus supplied power(KVA). This is important because a low power factor can waste energy, result in inefficient use of electrical power, and often result in higher energy bills. Power Factor Correction will improve the energy efficiency of any electrical system, but a reduction in your power bill is only available where a power company charges ...

Harmonics in power system. In an electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system, produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated magnetic devices. Harmonic frequencies in the power grid are a frequent cause of power quality problems. Harmonics in power systems result in increased hea...

Harmonics and Active Power Filter In recent years, the use of non-linear load is increasing day by day. Non-linear loads such as traditional diode/ thyristor rectifiers with inductive load generate harmonic and reactive current, which leads to poor power factor, low energy efficiency, and harmful disturbance to other appliances. Also, in recent years, the large-scale use of the power electronic eq...
