Güç Sistemlerinde Harmoniklerin Yapay Zeka Destekli Kısa Dönemli Kestirimi

Öz

Elektrik enerjisine olan ihtiyacın artması beraberinde daha verimli sistemlerin kullanımı gereksinimini ortaya çıkarmıştır. Teknolojinin ilerlemesiyle birlikte birçok alanda yarı iletken malzemelerin kullanılması, güç sistemlerinde doğrusal olmayan karakterli yüklerin artmasına neden olmuştur. Sözkonusu yüklerin güç sistemi üzerindeki bozucu etkileri filtreleme yolu ile giderilmekle birlikte, önceden bilinerek önlem alınması sistem işletme güvenliği açısından büyük fayda sağlayacaktır. Bu çalışmanın temel motivasyonu bu kapsam üzerine tesis edilmiştir. Çalışmada öncelikle bir veri seti oluşturulması amacıyla MATLAB/Simulink platformunda bir güç sistemi tasarlanmış, bu sistemde ortaya çıkan harmonik bozulmalar Hızlı Fourier Dönüşümü aracılığıyla tespit edilmiştir. Analiz vasıtasıyla oluşturulan veri seti, yapay sinir ağları modeli ile işlenmiştir. Elde edilen sonuçlar ve grafikler üzerinden sistemin başarımı incelenmiştir.

Artificial Intelligence Based Short-Term Estimation of Harmonics in Power Systems

Öz

The increasing demand for electrical energy has led to the need for more efficient systems. With the advancement of technology, the use of semiconductor materials in many areas has led to an increase in nonlinear loads in power systems. Although the disturbing effects of these loads on the power system can be eliminated by filtering, taking precautions by knowing in advance will be of great benefit in terms of system operational safety. The main motivation of this study is based on this scope. In the study, firstly, a power system is designed in MATLAB/Simulink platform in order to create a data set and the harmonic distortions occurring in this system are detected by means of Fast Fourier Transform. The data set generated by the analysis was processed with an artificial neural network model. The performance of the system is analyzed through the obtained results and graphs.
