This paper presents a study and solution of
different power quality issues of Jaipur Metro Rail
Corporation (JMRC) power supply system. The
measurement of different parameters was taken at
132kv incoming feeder of Jaipur Metro Receiving Sub
Station. The measured data were analyzed and different
power quality issues like excess reactive power; current
harmonics and load unbalancing were observed. These
power quality issues makes power factor poor. A
solution of these power quality issues using Active
Harmonics Filter has been proposed.
Keywords : Power Quality, Harmonics, Load unbalancing, Reactive Power, Power Factor, Active Harmonics filter, Non Linear Loads, Total harmonics Distortion (THD).
