Abstract

Before any electrical system is used in industrial applications, its behavior under different operating conditions must be studied. A mathematical model must be constructed beforehand in order to observe the behavior of the system under different conditions. Modeling of three-phase asynchronous motors with an electromechanical converter is very difficult due to the time varying current and voltage. While performing dynamic analysis of such motors, a common reference system must be determined. The most commonly used methods to facilitate the analysis of three-phase induction motors are Clarke-Park transforms. In this study, a visual interface has been prepared to ease the teaching of Clarke-Park transforms. The users are moved from the 3-phase (A,B,C) axis to the reference 2 phase (α,β) axis through the interface and to the (d,q) axis with the θ angle at the magnitudes defined in the (α,β) axis system. With the interface prepared, users can change the voltage, frequency and angle values and graphically observe their effect on Clarke and Park transforms. In addition, the conversion from 2-phase axis to 3-phase axis is made with inverse Clarke and Park transforms. Mathematical modeling of the transform and the interface were made using LabVIEW.

Abstract

Herhangi bir elektriksel sistem, endüstriyel uygulamalarda kullanılmadan önce farklı çalışma koşulları altında davranışlarının incelenmesi gerekmektedir. Sistemin farklı koşullarda davranışlarının gözlemlenebilmesi için öncelikle matematiksel modeli oluşturulmalıdır. Bir elektromekanik dönüştürücü olan üç fazlı asenkron motorların zamanla değişen akım ve gerilim ifadesinden dolayı modellenmesi oldukça zordur. Bu tarz motorların dinamik analizi yapılırken ortak bir referans sistem belirlenmesi gerekmektedir. Üç fazlı asenkron motorların analizini kolaylaştırmak için en çok kullanılan yöntemler Clarke ve Park dönüşümleridir. Bu çalışmada Clarke ve Park dönüşümlerinin öğretilmesi amacıyla görsel bir arayüz hazırlanmıştır. Kullanıcılar arayüz aracılığıyla 3 fazlı (A,B,C) eksenden referans 2 faz (α,β) eksene ve (α,β) eksen sisteminde tanımlanmış büyüklüklerde θ açısıyla (d,q) eksenine taşınmaktadır. Hazırlanan arayüz ile kullanıcılar gerilim, frekans ve açı değerlerini değiştirerek bunların Clarke ve Park dönüşümleri üzerine olan etkisini grafiksel olarak gözlemleyebilmektedir. Ayrıca ters Clarke ve Park dönüşümleriyle 2 fazlı eksenden 3 fazlı eksene dönüşüm yapılmaktadır. Dönüşümün matematiksel modellenmesi ve arayüz LabVIEW programı kullanılarak yapılmıştır.
