With the rapid use of power electronic converters which are considered as non-linear loads have problems of drawing non-sinusoidal currents and reactive power from source which in turn pollutes the power quality. This paper presents the power quality problems and methods for its correction where two control strategies (p q instantaneous power theory and d q synchronous reference frame theory) f...

This paper proposes a matrix converter based unified power quality conditioner (MC–UPQC) for mitigating power quality problems. This proposed system is a combination of unified power quality conditioner and matrix converter. The UPQC is a combination of back-toback connected series and shunt active filters through a dclink. Voltage disturbances and harmonics are compensated by series active fil...

Due to environmental conditions, the wind power generation is fluctuating in nature. This affects the electrical network interconnected with these systems. When the wind power generators are connected to the nonlinear loads, there is distortion in the waveform. These distortions should be within limits according to national and international guidelines framed for power quality. This paper prese...

Due to the advancement in power electronic equipments and increase in the usage of non-linear loads in power distribution system, the undesirable harmonics are introduced that degrade the quality of power. Presence of harmonics are always detrimental to power system that results in irreversible failure of electrical components, sometimes apart from frequently known heating issues in it. There a...
