Abstract

Electric power is the most essential raw material impacting the bottom line of quality production economically on a commercial scale. It can’t typically be stored like other commodities and is essentially required with continuous flow all the time. Electric power can be visualized as the epitome of ‘just in time’ philosophy used like the components delivered to a production line by a trusted and approved supplier with no facility for ‘pre-inspection’. Now a day due to increased use of power electronic device at the distribution level the efficiency and reliability of supply being supplied to consumers is deteriorating. The increased voltage sag, voltage swell, flicker and other power quality problem attract the attention of consumer toward quality of power being supplied to them. Increased PQ problems leads to increased power loss, malfunctioning of electrical equipment and large financial loss, therefore the issue need quick attention. In this paper an effort is made by author to resolve the voltage and current related issues with application of Unified Power Quality Conditioner in the preinstalled distribution networks where design change is not possible. The author used Direct Torque Controlled Induction Motor Drive as a nonlinear load and constant impedance RL load as linear one in a 3-phase, 4-wire distribution system and compared the results with and without use of UPQC
