Havai Rüzgar Enerji Sistemleri için Sürekli Mıknatıslı Senkron Generator Tasarım ve Optimizasyonu

Öz

Havai rüzgar enerjisi sistemleri (Airborne Wind Energy Systems), geleneksel rüzgar türbinlerine oranla yüksek rüzgar hızlarına ulaşabilmeleri ve daha az malzemeye gereksinim duymaları nedeniyle son yirmi yılda geleneksel rüzgar türbinlerine alternatif olarak geliştirilmiştir. Genellikle elektrik generatörünün konumuna göre tümleşik (on-board) veya yerde şeklinde sınıflandırılırlar ve her iki tipte de kule yerine kabloyu taşıyan bir halat bulunur. Bu makale, bir havai rüzgar enerjisi sistemi için sürekli mıknatıslı radyal tip elektrik generatörünün (pmsm) elektromanyetik tasarımını ve optimizasyonunu sunmaktadır. 44kW bir sistem için ünite ve güç sayısı değiştirilerek uygun güç-ağırlık (P/W) oranını ve makinenin verimini sağlayan optimal parametreler araştırılmıştır. Analitik modeli elde edilen makinenin optimizasyonu genetik algoritma yöntemi ile Matlab yazılımı kullanılarak gerçekleştirilmiştir. Tasarım sonuçlarının doğrulanması için sonlu elemanlar analizi yöntemi Ansys-Maxwell programında uygulanmıştır.

Permanent Magnet Synchronous Generator Design and Optimization for Airborne Wind Energy Systems

Abstract

Airborne wind energy systems have been developed as an alternative to conventional wind turbines in the last two decades since they can reach higher wind speeds and require less material than conventional wind turbines. They are generally classified as on-board or ground based depending on the location of the electric generator, and both types have a tether carrying the cable instead of the tower. This article presents the electromagnetic design and optimization of a permanent magnet synchronous generator (radial type) for an airborne wind power system. For a 44kW system, the optimal parameters that provide the appropriate power-to-weight (P/W) ratio and the efficiency of the machine were investigated by adjusting the number of units and power. The optimization of the machine, whose analytical model was obtained, was carried out using Matlab software utilizing the genetic algorithm method. Three-dimensional finite element analysis method was used to verify the design results with the Ansys-Maxwell program.
