Design of permanent magnet synchronous generator for low speed and small power wind turbines

Abstract

In this paper, an exemplary study on the design of radial flux permanent magnet synchronous generators (PMSGs) for small power-low speed wind turbines and its modelling and performance analysis in Ansys Maxwell software is presented. In this exemplary study, firstly, the design is obtained by using analytical expressions. Subsequently, the two-dimensional model of the design is provided in Ansys Maxwell software. Thus, the variation of the voltage effective value, voltage total harmonic distortion value, current effective value and efficiency parameters of the same design depending on the loading ratio, and the variation of these four parameters and maximum output active power depending on the speed are evaluated.

Düşük hızlı ve küçük güçlü rüzgar türbinleri için kalıcı mıknatıslı senkron generatör tasarımı

Abstract

Bu makalede, küçük güçlü düşük hızlı rüzgar türbinleri için radyal akılı kalıcı mıknatıslı senkron generatörlerin (KMSG’lerin) tasarımı ile Ansys Maxwell yazılım ortamında modellenmesi ve performans analizi üzerine örnek bir çalışma sunulmuştur. Bu örnek çalışmada, öncelikle analitik ifadeler kullanılarak; hedeflenen anma değerlerine sahip bir KMSG tasarımı yapılmıştır. Devamında, Ansys Maxwell yazılım ortamında iki boyutlu modelleme yaklaşımıyla, tasarımın, yüklenme oranı değişimine bağlı olarak gerilim etkin değeri, gerilim toplam harmonik bozulma değeri, akım etkin değeri ve verim performans parametrelerinin değişimi, ayrıca milin dönme hızının değişimine bağlı olarak bu dört performans parametresinin yanı sıra üretilen azami aktif güç değerinin değişimi analiz edilmiştir.
