Generation and Verification of Signals of Power Quality Events by LabVIEW

Abstract

Factors that deteriorates the quality of electrical power are of great economic importance. In recent years, intensive studies have been carried out on the detection and solutions of power quality problems. An important part of academic studies is carried out with the simulated data. Although there are a limited number of studies on production of simulation data, it is noteworthy that the data used in these studies are almost never checked whether they comply with the standards. In this study, signals of power quality problems are produced in LabVIEW environment. A data validation application was designed and tested to determine whether the produced signals comply with the relevant standards. The data validation application performs validation using algorithms developed based on the definitions of power quality events given in the relevant standards. The obtained results shows that the designed application can be used in the verification of the simulated power quality signals and will contribute to the academic studies on power quality.

Güç Kalitesi Olay İşaretlerinin LabVIEW ile Üretilmesi ve Doğrulanması

Abstract

Elektrik güç kalitesini bozan etkenler ekonomik açıdan büyük öneme sahiptir. Güç kalitesinde meydana gelen bozulmaların tespit edilmesi ve çözüm yöntemlerinin geliştirilmesi üzerine son yıllarda yoğun olarak çalışmalar yapılmaktadır. Akademik çalışmaların önemli bir kısmı simülasyon verileriyle gerçekleştirilmektedir. Simülasyon verilerinin nasıl elde edildiğine ilişkin sınırlı sayıda çalışma olmakla birlikte bu çalışmalarda elde edilen verilerin standartlara uygun olup olmadığının hemen hemen hiç denetlenmediği dikkati çekmektedir. Bu çalışmada güç kalitesi problemlerine ait işaretler LabVIEW ortamında üretilmektedir. Üretilen işaretlerin ilgili standartlara uygun olup olmadığını tespit etmek için bir veri doğrulama uygulaması tasarlanarak test edilmiştir. Veri doğrulama uygulaması ilgili standartlarda verilen tanımlara dayalı olarak geliştirilen algoritmaları kullanarak doğrulama yapmaktadır. Elde edilen sonuçlar ile tasarlanan uygulamanın simülasyon yoluyla üretilen işaretlerin doğrulanmasında etkin olarak kullanılabileceği ve güç kalitesi alanındaki akademik çalışmalara katkı sunabileceği değerlendirilmektedir.
