Abstract
End users of electricity want to receive a quality and reliable electric power without interruption all the time throughout year. Even though, power generation station maintains quality, some natural and man-made sources affect the quality of electric power supply being distributed. Various conventional devices are available to improve electric power quality, but their performance is inadequate. The main aim of the work is to design and simulate a system which provides quality and reliable electric power. The system uses Distribution STATic COMpensator (DSTATCOM) to maintain the power at near sinusoidal voltage and at designed frequency. DSTATCOM is a shunt connected Voltage Source Inverter (VSI) based custom power device, used to mitigate power quality issues. The system also uses the fuzzy logic control algorithm, to control the Pulse Width Modulation (PWM) controllers used in VSI of DSTATCOM.
Highlights
IntroductionAn electric power at sinusoidal voltage and current, without any distortion and being at its designed level of magnitude and frequency
Quality electric power means, an electric power at sinusoidal voltage and current, without any distortion and being at its designed level of magnitude and frequency
For example voltage dip will be faced by a consumer who connected in a line supplying heavy motor load
Summary
An electric power at sinusoidal voltage and current, without any distortion and being at its designed level of magnitude and frequency. For example voltage dip will be faced by a consumer who connected in a line supplying heavy motor load. Life support and operation theatre loads in hospitals, food processing plants, semiconductor industries and data processing industries are sensitive loads and requires clean and uninterrupted electricity, since the loss due to power quality issues will be more here. Requirements like these have increased the significance of electric power quality which introduced power electronics based custom power devices (CPDs) [1,2,3,4]
