Abstract

Bu çalışmada, MATLAB/Simulink ortamında modellenen iki-seviyeli bir evirici ile sabit mıknatıslı senkron motor(SMSM) tahrik edilmiştir. Gerçek test düzeneklerindeki sonuçlara uyumlu sonuçlar verebilecek bir simülasyon modeli oluşturulmuştur. Gerçeğe uygun sonuçlar ve dalga şekilleri elde edebilmek için ideal modeller yerine eşdeğer modeller kullanılmıştır. Örneğin, SMSM elektriksel ve mekanik eşdeğer modellerinin kullanılması, şebeke tarafına direnç ve endüktans katkılanması ve DC bara kapasitörünün eşdeğer direnci(ESR) ile birlikte modellenmesi elde edilen sonuçların gerçek test düzeneklerinden alınan sonuçlara yakınsamasını sağlayacaktır. SMSM, açık-çevrim olarak kontrol edilmiştir. Yarı-iletken anahtarlar için gerekli kapı işaretleri SPWM(Sinüzoidal Darbe Genişlik Modülasyonu) anahtarlama yöntemi ile üretilmiştir. Bu PWM(Darbe Genişlik Modülasyonu) yönteminin çalışma mantığı detaylı olarak incelenmiştir. Evirici üzerindeki yapıların anlaşılması için simülasyon modelleri, önemli parametreler ve matematiksel denklemler ilgili bölümlerde sırasıyla verilmiştir. Verilen simülasyon görüntülerinde evirici ve SMSM üzerindeki birçok önemli noktanın akım-gerilim dalga şekilleri incelenmiştir. Şebekeden çekilen akım, DC bara kapasitörü üzerindeki gerilim dalgalanması, SPWM yöntemiyle üretilen anahtarlama işaretleri, evirici çıkış faz akımları, motor faz-nötr gerilimleri, motor faz-faz gerilimleri önemli görülen ve bu çalışma kapsamında sunulan işaretlerdir. Özellikle, güç hesabının yapılabilmesi için evirici çıkış akım-gerilim işaretleri verilmiştir. Tüm bu temel incelemelerden sonra, evirici çıkış gücü yani motor giriş gücü ölçülmüştür. Motor faz akımı ve faz-nötr gerilimi arasındaki faz açısı bulunmuştur. Son olarak Simulink ortamında yapılan bu ölçümler, teorik hesaplamalarla kıyaslanmış ve modellerin doğruluğu ispatlanmıştır.

Abstract

In this study, a permanent magnet synchronous motor (PMSM) was driven by a two-level inverter modeled in MATLAB / Simulink environment. A simulation model has been created that can give results compatible with the results in real test setups. In order to obtain realistic results and waveforms, equivalent models were used instead of ideal models. For example, the use of PMSM electrical and mechanical equivalent models, adding resistance and inductance to the grid side, and modeling the DC bus capacitor with equivalent series resistance (ESR) will ensure the convergence of the obtained results to the results from real test setups. Open-loop control of PMSM has been provided. Gate signals required for semiconductor switches were produced by SPWM (Sinusoidal Pulse Width Modulation) switching method. The working principle of this PWM (Pulse Width Modulation) method has been studied in detail. In order to understand the structures on the inverter, simulation models, important parameters, and mathematical equations are given in the relevant sections respectively. In the given simulation outputs, the current-voltage waveforms of many important points on the inverter and PMSM were examined. Current drawn from the grid, voltage ripple on the DC bus capacitor, switching patterns produced by the SPWM method, inverter output phase currents, motor phase-to-neutral voltages, motor phase-to-phase voltages are the waveforms that are considered as important and presented within the scope of this study. In particular, the inverter output current-voltage signals are given for power calculation. After all these basic examinations, the inverter output power, as known as the motor input power, was measured. The phase angle between the motor phase current and phase-neutral voltage was found. Finally, these measurements made in the Simulink environment were compared with theoretical calculations and the accuracy of the models was proved.
