Elektrik şebekelerinde en ciddi güç kalitesi problemlerinden biri gerilim düşüşleridir. DVR, bu güç kalitesi problemlerinin çözümünde kullanılan yaygın özel güç cihazları olarak bilinmektedir. Bu çalışmada, şebeke gerilim kesintileri, gerilim düşmeleri ve gerilim yükselmelerinin hızlı ve güvenilir bir şekilde tespiti için rüzgar enerjisi sistemi altındaki DVR'nin kontrol devresinde WCA algoritması ile optimizasyon yapılmış, performansları geleneksel PI kontrolöre göre değerlendirilmiştir. Bu kontrol yöntemleri, şebeke geriliminin genlik ve faz bilgilerini anlık olarak çıkararak gerilim değişikliklerini hızlı ve doğru bir şekilde tespit edebilir ve bu bilgiler yardımıyla,
bağlantı noktasına enjekte edilmesi gereken voltaj elde edilebilir. Simülasyon çalışmasında, DFIG tabanlı rüzgar enerjisi sisteminde DVR tarafından üretilen ve sisteme enjekte edilen gerilimler de bu iki farklı kontrol yöntemi kullanılarak sunulmuştur.
WCA tabanlı PI denetleyicinin üstünlüğü sonuçlarda açıkça görülmektedir.

Voltage Sag Mitigation with DVR optimized in DFIG based Wind Energy System

Öz

One of the most serious power quality problems in electrical networks is voltage drops. The DVR is known as the most common special power devices used in solving these power quality problems. In this study, optimization is made with WCA algorithm in DVR’S control circuit under wind energy system for fast and reliable detection of mains voltage disruptions, voltage drops and voltage spikes, Its performances were evaluated according to conventional PI controller. These control methods can instantly extract the amplitude and phase information of the mains voltage to detect voltage changes quickly and accurately and with the help of this information, The voltage that needs to be injected into the connection point can be obtained. In the simulation study, the tensions produced by DVR in DFIG based wind energy system and injected into the system were also presented using these two different control methods. The superiority of WCA-based PI controller is clearly seen in the results.
