Application of PI, Fuzzy Logic and ANN in Improvement of Power Quality using Unified Power Quality Conditioner
The unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both current and voltage harmonics at a distribution side of power system network. This paper emphasis enhancement of power quality by using UPQC with fuzzy logic controller (FLC) and proportional-integral (PI) controller. The main purpose of the proposed (FLC) is capable of pr...
متن کاملPerformance Study of Unified Power Quality Conditioner Using Matlab Simulink
Modern power system comprises of complex networks, where many generating stations and load centres are interconnected through long power transmission and distribution networks. Utility distribution networks, critical commercial operations and sensitive industrial loads all suffer from various types of outages and interruptions which can lead to significant financial loss, loss of production, id...
متن کاملPower Quality Improvement of Unified Power Quality Conditioner Using Reference Signal Generation Method
This project presents a power quality improvement of unified power quality conditioner (UPQC) to compensate current and voltage quality problems of sensitive loads. The UPQC consists of the series and shunt converter having a common dc link. The series converter mitigates voltage sag from the supply side and shunt converter eliminates current harmonics from the nonlimear load side. The develope...
متن کاملPower Quality Improvement using Voltage Source Converter (VSC) based Unified Power Quality Conditioner (UPQC)
In recent years, there is tremendous growth in the use of power electronic devices in every sphere but in nonlinear loads, it has problem of drawing the two important limitations; draws the non-sinusoidal current and reactive power from source which in turn effects the power quality. This paper presents the performance evaluation of unified power quality conditioner (UPQC) for current and volta...
