Elektrik Makinalarında Harmonik ve Ara-Harmonik Analizi

Abstract

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. According to the analysis results, the 3.5th component was determined as the most dominant harmonics with a rate of 10.27% among the interharmonics. Another interharmonic, 4.5th component, was detected at a rate of 5.19%. While the ratio of the 5th harmonic component among the main harmonics was 1.29%, the ratio of the 5.5th component, which is the interharmonic, was 3.32%.

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. Analiz sonucunda, ara-harmoniklerden 3,5’inci bileşen %10,27 oranı ile en baskın harmonik olarak çıkmıştır. Diğer bir ara-harmonik olan 4,5’inci bileşen de % 5,19 oranında tespit edilmiştir. Ana harmoniklerden 5’inci harmonik bileşenin oranı %1,29 iken ara-harmonik olan 5,5 bileşenin oranı % 3,32 belirlenmiştir.
