his paper presents the analysis of real power system
events recorded at a light industrial site to determine the effect of
a shunt active filter on power quality. The shunt active fdter is
shown to improve power quality by lowering the distodon of the
supply voltage in both the transient and steady state. The shunt
active filter power rating and other design information are also
determined. The performance degradation of the shunt active
fdter when it has a limited rating is then demonstrated. In one
case the voltage distortion is made worse by the active fdter. The
requirements that various transient events, including capacitor
switching and induction motor starts, place on the shunt active
tilter design ace outlined. These requirements are such that the
required switching frequencies exceed those attainable with
ICBTs and transient ratings dominate the active fdter design
constraints.
