IG ve DFIG’lerin Rüzgar Gücü Üretim Sistemleri İçin Karşılaştırılması

Abstract

İndiksiyon ve iki beslemeli indiksiyon generatörleri rüzgar gücü sistemlerinde elektrik üretimi için yaygın olarak kullanılır. İndiksiyon generatörlerin ve iki beslemeli indiksiyon generatörlerin tanımları rüzgar enerji sistemleri için bu çalışmada verilmiştir. Farklı bağlantı tipleri ve koşulları iki farklı rüzgar jeneratörü için şebeke ve rüzgar türbinleri için bu çalışmada incelenmiştir. Bir rüzgar çiftliği modeli indiksiyon generatörü ve iki beslemeli indiksiyon generatörü için MATLAB/Simulink de modellenmiştir. İlk olarak simulasyon sonuçları normal çalışma koşulları için sunulmuş ve tartışılmıştır. İkinci olarak ise rüzgar çiftliği modeli hata durumları için simule edilmiştir. Farklı hata koşulları altındakı bu IG ve DFIG sonuçları statik kompanzatörün bir fonksiyonu olarak verilmiş ve tartışılmıştır. Bu sistemin üstünlük ve dezavantajları verilmiş ve değerlendirilmiştir.

Comparison of IG and DFIG for Wind Power Generation Systems

Abstract

Induction and doubly-fed induction generators are widely used in wind power systems for electricity generation. Description of induction generator (IG) and doubly-fed induction generator (DFIG) for wind power generation systems are given in this paper. Different connection types and conditions for two different types of wind generators with the grids and wind turbines are investigated in this study. A wind farm model is simulated using an induction generator and a doubly-fed induction generator in MATLAB/Simulink. The simulation results under normal operating conditions are presented and discussed firstly. Wind farm models are simulated under fault conditions secondly. The results of the IG and DFIG system under various fault conditions as a function of static compensator (STATCOM) are presented and discussed. The superiority and disadvantages of this system are given and evaluated.
