Abstract

Because of its lower power consumption in comparison to linear load, non-linear load is gaining popularity at an increasing rate. In spite of the fact that power electronic equipment makes our lives easier, it also contributes to the harmonics that are present in the power system. Because of the influence that these harmonics have on the amplitude and character of the source current as well as the performance of the system, power quality has become a very severe issue. provides information on the necessity of clean power, harmonics, and the effect that they have on the power system. Harmonic examination of a variety of nonlinear loads, as well as a narrative on harmonic norms and standards. The need of installing certain corrective measures in the system so that the problem may be solved by reducing the amount of harmonic energy used in both the single-phase supply and the three-phase supply. describe the shunt active power filter this chapter explains all you need to know about the SAF and how it works as a harmonic compensator. A discussion is held on its operations, design, and configuration. The shunt active power filter is more adaptable, better damped, and less prone to failure than other active power filters. Because the performance of SAPF is dependent on the control algorithm used for reference current generation, which is then used as reference for filter current, the third chapter describes the various control techniques that are used for active filter operation. PWM generation using reference current is the primary focus of this discussion. Last but not least, this filter current is put to use for the purpose of compensating for harmonics. By doing so, harmonic reduction and an improvement in power quality are both possible.
