Power quality: the key to successfully ensuring quality products and operations in industry. Both power companies and electricity end users are increasingly concerned about the quality of electricity. The term power quality has become one of the most widespread buzzwords in the energy sector since the late 1980s. Power quality can also be defined as the degree to which both the use and supply of electrical energy affect the performance of electrical equipment. It is now even more critical for the industry due to the growing application of electronic loads and electronic controllers sensitive to the quality of the supplied energy. To meet the limitations of the PQ standard, it may be necessary to include some sort of compensation. Modern solutions can be found in the form of active rectification or active filtering. A shunt active power filter is suitable for suppression of the negative load influence on the supply network, but if supply voltage imperfections are present, a series active power filter may be required to provide full compensation. Conventionally, passive LC filters and fixed compensation devices with a certain degree of variation such as thyristor switched capacitors, thyristor switched reactors have been employed to improve the power factor of AC loads. Such devices have the demerits of fixed compensation, large size, aging and resonance. Nowadays equipment using power semiconductor devices, generally known as active power filters (APF), active power line conditioners (APLC) etc. are used for power quality problems due to their dynamic and tunable solutions.Institute of Electrical and Electronic Engineers (IEEE) The IEEE1100 standard defines power quality... middle of paper... a distribution system healthier, multi-converter unified power quality conditioner (MC-UPQC) is one of the best solutions [11]–[17 ]The objective of this project is to understand the modeling and analysis of an active power filter in shunts. Thus, the accuracy of current compensation for detected current harmonics on a nonlinear load is supported for the PQ theory control technique and also proves the reliability and effectiveness of this model for integration in a network of power systems.
