Gelişen teknolojiyle birlikte elektrik enerjisine olan ihtiyaç her geçen gün artmaktadır. Elektrik enerjisinin dağıtımı sırasında birçok hata (gerilim yükselmeleri, gerilim sarkmaları, harmonikler) meydana gelebilmektedir. Bu hataları düzeltmek için STATCOM ve DVR gibi sistemler kullanılmaktadır. Böylece enerjinin kalitesi arttırılmaya çalışılmaktadır. Bu çalışmada; hata olarak gerilim sarkmasının meydana geldiği bir iletim hattına yük bağlanarak bu yükün gerilim sarkması karşısındaki durumu ve hassasiyeti, ardından düzeltici olarak DVR kullanıldığındaki durumu ve hassasiyeti araştırılmıştır. DVR sisteminin yükler karşısındaki durumu detaylı olarak incelenmiştir. İlgili veriler MATLAB/Bulanık Mantık uygulamasına aktarılarak analiz edilmiştir.

FUZZY LOGIC APPLICATION TO SHOW LOAD SENSITIVITIES AGAINST VOLTAGE SAG

Öz

With the developing technology, the need for electrical energy is increasing day by day. Many power quality problems such as voltage spikes, voltage sags, harmonics can occur during the distribution of electrical energy. Systems such as STATCOM and DVR are used to correct these problems. Thus, the quality of the energy is tried to be increased. In this study; By connecting a load to a distribution line where voltage sag occurs as an error, the condition and sensitivity of this load against voltage sagging, and then the condition and sensitivity when using DVR as a corrector, were investigated. The situation of DVR against the loads has been analyzed in depth. Relevant data have been transferred to MATLAB / Fuzzy Logic application and analyzed.
