Intelligent controlled UPQC for power quality improvement of grid supply connected with non-linear load
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 6
Abstract
The issue of power quality has gained popularity in the recent years because of the widespread use of power electronic devices, larger inter-connected load networks and widespread use of non-conventional source of electrical energy like wind power, solar power etc. in the power system. The deterioration of the power quality may cause unwanted losses in the system, poor efficiency, interference with the communication lines, and faulty operation of devices and even may cause fault in some devices. In this paper the power quality issue because of the presence of non-linear load connected to the electric grid is discussed and an effort has been made to improve the power quality of the system using a device known as Unified Power Quality Conditioner (UPQC). For this the intelligent controlled UPQC is developed and used with the Grid supply connected to the Non-linear load and percentage Total Harmonic Distortion (THD) of voltage and current waveforms is measured in order to determine the power quality at different locations in the system. The intelligent controlled method has been found to have superior performance over the conventional Proportional Integral (PI) controlled UPQC. The results obtained verified using MATLAB/SIMULINK software.
