ANAHTARLAMALI RELÜKTANS MAKİNALARIN AKI VE ENDÜKTANS ÖLÇÜM METOTLARININ İNCELENMESİ

Öz

Bu makalede anahtarlamalı relüktans makinaların akı ve endüktans ölçüm metotları incelenmiştir. Genel olarak kullanılan üç ölçme metodu statik DC, statik AC ve dinamik ölçme metotları ayrı ayrı ele alınmıştır ve aralarındaki farklar ortaya konulmuştur. Amaç anahtarlamalı relüktans makinaların endüktans profilinin çıkartılmasında hangi yöntemin daha uygun olduğunun ortaya koyulmasıdır. Bu amaca yönelik olarak öncelikle gerçek anahtarlamalı relüktans makinaların endüktans profiline yakın bir endüktans modeli belirlenmiştir. Bu model kullanılarak ölçme yöntemlerinin benzetim çalışmaları gerçekleştirilmiştir. Aynı zamanda 8/6 bir anahtarlamalı relüktans makina ile ölçümler yapılarak deneysel sonuçlarla da bu benzetimsel çalışma desteklenmiştir.

INVESTIGATION OF FLUX AND INDUCTANCE MEASUREMENT METHODS OF THE SWITCHED RELUCTANCE MACHINES

Öz

In the present study, flux and inductance measurement methods of the switched reluctance machines have been investigated. The three measurement methods which are static DC, static AC and dynamic measurement methods have been discussed separately, and difference among them have been introduced. The aim is to present the proper method for the providing the inductance profile of the switched reluctance machine. For this reason, firstly an inductance model that approximates the real inductance profile of the switched reluctance machine has been identified. Simulation studies of the measurement methods have been achieved by using this model. The simulation results have been proved with experimental measurements of an 8/6 switched reluctance machines.
