A Review on Power Quality Improvement by UPQC

Sneha Bageshwar | Dr. D. P. Kothari

Abstract: The introduction of power electronic based equipment has produced a great impact on the quality of electrical power supply. Modern day equipments are highly sensitive to variation from ideal sinusoidal voltages. Conventional power quality improvement equipments are providing solution but not sufficient. A very promising solution for supply voltage imperfection is UPQC (Unified Power Quality Conditioner), which allow the mitigation of voltage and current disturbances that could affect sensitive electrical loads while compensating the load reactive power. This paper presents a review on the unified power quality conditioner (UPQC) to improve electric power quality. Connection methodologies with their advantages and disadvantages are also described.
