Power system analysis and design 5th solution pdf
Wärtsilä - Enabling sustainable societies with smart technologyIn 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 heating in the equipment and conductors, misfiring in variable speed drives, and torque pulsations in motors. In a normal alternating current power system, the current varies sinusoidally at a specific frequency, usually 50 or 60 hertz. When a linear electrical load is connected to the system, it draws a sinusoidal current at the same frequency as the voltage though usually not in phase with the voltage. Current harmonics are caused by non-linear loads. When a non-linear load, such as a rectifier is connected to the system, it draws a current that is not necessarily sinusoidal.

A new benchmark in efficiency and overall emissions performance. It is usually the case that we neglect higher voltage harmonics; however, real power transferred to the load is affected by harmonics.
