Report Progress for Senior Research Laboratory By: Cheryl W. Aglipay
Title: PC-Based Online Power Quality Monitoring Research Advisor and Mentor: Dr. Oguz Soysal Instructor: Dr. Stephen Luzader Course: PHYS 400 (Senior Research and Seminar in Physics) Date: 16 Apr 01 (Mon) Last week was more time spent doing more research. My advisor and I found some articles in the following journals: IEEE Transactions on Power Delivery, IEEE Transactions on Industrial Application, and IEEE Transactions on Power Systems. We took interest in the term flicker, which is from the impact of the voltage fluctuation on lamps such that they are perceived to flicker by the human eye. In the book "Electrical Power Systems Quality," it states, "to be technically correct, voltage fluctuation is an electromagnetic phenomenon while flicker is an undesirable result of the voltage fluctuation in some loads." On Friday, we planned on meeting to discuss what we planned on doing to collect data to obtain a voltage waveform which produces flicker. However, I was not able to meet with Dr. Soysal so the data collection was neglected. The plan was to hook up the voltmeter to my computer to collect data for the voltage fluctuations my in dorm over the weekend. This week I will talk to Dr. Soysal to collect data during the final week of data collection. Also, I will definitely work with collecting data for long-duration variation and the formulation of a VI (virtual instrument) on LabVIEW. During my research I touch on the following topics: I. Voltage Sags and Interruptions A. Sources of Sags and Interruptions Voltage sags and interruptions are generally caused by faults (short circuits) on the utility system. B. Area of Vulnerability Area of Vulnerability has been developed to help evaluate the likelihood of being subjected to voltage sags lower than a critical value. C. End-User Issues End-User Issues are used for many applications, however, the Mot...
