Abstract

If
power quality can be maintained, high performance is possible for electrical
devices. Harmonics is one of such problems that can cause performance to drop.
Therefore, harmonics must be detected and prevented. This study aimed to be
part of detection system designed to maintain power quality. Akaike Information
Criterion is used to calculate features for power quality analysis. And for
classification k-Nearest Neighbor classification is used. %94.8 accuracy is
obtained from training set and %91.7 accuracy is obtained from test set. MATLAB
is the program which is used for classification and feature calculation.

Harmoniklerin Akaike Bilgisi Kriterini Kullanarak K-En Yakın Komşu Sınıflandırması

Abstract

Elektrik kalitesi korunabiliyorsa, elektrikli
cihazlar için yüksek performans mümkündür. Harmonikler, performans düşmesine
neden olan bu tür sorunlardan biridir. Bu nedenle, harmonikler tespit edilmeli
ve engellenmelidir. Bu çalışma, güç kalitesini korumak için tasarlanan algılama
sisteminin bir parçası olmayı amaçlamıştır. Akaike Bilgi Kriteri, güç kalitesi
analizi için özellikleri hesaplamak için kullanılır. Ve sınıflandırma için k-En
Yakın Komşu sınıflandırması kullanıldı. Eğitim setinden% 94.8 doğruluk elde
edilmiştir ve Test setinden% 91.7 doğruluk elde edilmiştir. MATLAB,
sınıflandırma ve özellik hesaplama için kullanılan programdır.
