The distortions of input voltage and current waveforms generated by switch mode power supply (SMPS) operation are a major cause of concern in the power quality performance of commercial office buildings. These distortions are usually evaluated by performing a site survey of the building. In this thesis, a power quality simulator is proposed as an alternative method to site surveys in evaluating the power quality characteristics of such nonlinear loads in a commercial environment.
The power quality simulator is built around the assumption that the total load kVA on each phase of the three-phase four-wire distribution system can be approximated. The proposed simulator is tested on two commercial office buildings, namely the Owen Hall and Dearborn Hall buildings of Oregon State University. Experimental time-domain and frequency-domain waveforms are presented. These are compared with the simulation results to prove the viability of the power quality simulator in determining the power quality characteristics of the building. Finally, a passive filtering technique was simulated to reduce the harmonic distortions in voltages and currents to further demonstrate the potential uses of the power quality simulator. / Graduation date: 2000
