The firstof these methods is to use the derivative information of the state variables based on the system observabilityprinciple. The second is the use of instantaneous active and reactive power measurement results as a new method.The classical equivalent circuit model is used in steady-state studies of parameter estimation methods. In dynamicsystems, methods based on nonlinear minimization of the cost function, different initial values, and giving moreprecise estimation results are used. In this study, the dynamic system structure is set up as the square sum of thedifference between parameter estimate values. Different parameter estimation methods were used forasynchronous machine models, and test results under no load and full load were examined. The impedancemeasurement results in parameter estimation methods were compared with the measurement results obtained fromthe model. It has been shown that the test results performed in real time are very close to the offline and nonlinearparameter estimation values and their accuracy has been proven. KW - Asynchronous Machine KW - Vector Control KW - Dynamic Model KW - Parameter Estimation Methods N2 - Asenkron makinaların dinamik model vektör kontrol uygulamalarında iki farklı yöntem kullanılmaktadır. Buyöntemlerden ilki sistem gözlenebilirlik ilkesine dayanan durum değişkenlerine ait türev bilgilerininkullanılmasıdır.İkincisi ise yeni bir yöntem olarak önerilen aktif ve reaktif güç ölçüm sonuçlarının anlık olarakpaylaşılmasıdır. Parametre tahmin yöntemlerinin kararlı durum çalışmalarında klasik eşdeğer devremodelikullanılmaktadır. Dinamik sistemlerde ise,maliyet fonksiyonunun doğrusal olmayan minimizasyonunadayanan, başlangıç değerleri birbirinden farklı olan ve daha kesin tahmin sonuçlarıveren yöntemlerkullanılmaktadır. Bu çalışmada, dinamik sistem yapısı parametre tahmin değerleri arasındaki farkın kareseltoplamı olacak şekilde kurulmuştur. Asenkron makine modelleri için farklı parametre tahmin yöntemlerikullanılmış, yüksüz ve tam yük altındaki testsonuçları incelenmiştir. Empedans ölçümsonuçları ile, modelden eldeedilen ölçüm sonuçları karşılaştırılmıştır. Gerçek zamanlı gerçekleştirilen deney sonuçlarının çevrimdışı olarak gerçekleştirilen ve doğrusal olmayan parametre tahmin değerlerineçok yakın oldukları gösterilmiş ve doğruluklarıispatlanmıştır.
