(1998) The transient and steady state performance of a shunt active filter using measured site data. Athens, Greece: Proceedings of the International Conference on Harmonics and Quality of Power, v1, 1998. 395--400.http://hdl.handle.net/10092/1629This 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 filter is shown to improve power quality by lowering the distortion 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 filter when it has a limited rating is then demonstrated. In one case the voltage distortion is made worse by the active filter. The requirements that various transient events, including capacitor switching and induction motor starts, place on the shunt active filter design are outlined. These requirements are such that the required switching frequencies exceed those attainable with IGBTs and transient ratings dominate the active filter design constraints.enshunt active filterpower quality measurementstransient performanceConference Contributions - OtherFields of Research::290000 Engineering and Technology::290900 Electrical and Electronic Engineering::290901 Electrical engineeringFields of Research::290000 Engineering and Technology::299900 Other Engineering and Technology::299904 Engineering/technology instrumentation
