Elektrik Makinalarında Harmonik ve Ara-Harmonik Analizi

Elektrik enerjisinin üretimi, iletimi ve dağıtımında kalite koşullarının sağlanması, bir güç sisteminin sorunsuz çalışması için en önemli gerekliliklerden biridir. Özellikle teknolojik gelişmelere bağlı olarak sayıları artan hassas yükler için bu durum hayati önem taşımaktadır. Enterkonnekte sistem yapısı gereği üretim ve tüketim ünitelerinin birbirlerine bağlı olması, enerji kalitesi kavramının hem üretici hem de tüketiciler tarafından dikkate alınmasını gerektirir. Bu çalışmada, elektrik enerjisi üretiminin temel ünitelerinden biri olan sürekli mıknatıslı senkron generatörün harmonik ve ara-harmonik analizi yapılmıştır. Söz konusu analiz amacıyla tasarlanan generatör nominal çalışma koşulları altında çalıştırılmıştır. Çalışma kapsamında harmonik analizinin yanı sıra ara-harmonik analizi de yapılmıştır. Elde edilen sonuçlardan, bazı kademeler için ara-harmonik bozunum değerlerinin harmonik bozunuma göre daha yüksek olduğu tespit edilmiştir.

Harmonic and Inter-Harmonic Analysis in Electric Machines

Ensuring quality conditions in the generation, transmission and distribution of electrical energy is one of the most important requirements for the proper operation of a power system. This is of vital especially for sensitive loads, the number of which is increasing due to technological developments. The fact that the generation and consumption units are connected due to the structure of the interconnected system requires that the concept of energy quality be taken into account by both energy generation companies and consumers. In this study, harmonic and inter-harmonic analysis of the permanent magnet synchronous generator, which is one of the basic units of electrical energy production, has been made. The generator designed for the aforementioned analysis was operated under nominal operating conditions. In addition to the harmonic analysis, interharmonic analysis was also carried out within the scope of the study. From the results obtained, it has been determined that the inter-harmonic distortion values for some levels are higher than the harmonic distortion.
