Abstract

Lineer olmayan yük modellerinin sistem üzerinde oluşturmuş olduğu etkiler güç kalitesi açısından önemli bir konudur. Bu çalışmada, şebekeye bağlı Çift Beslemeli Asenkron Generatör (ÇBAG) tabanlı rüzgar türbininde lineer olmayan yük modellerin etkisi incelenmiştir. Lineer olmayan yük modeli olarak üstel, sabit empedans, sabit akım, sabit aktif güç (ZIP) ve asenkron motor kullanılmıştır. ÜstelZIP-Asenkron Motor biçiminde bileşik yük modeli oluşturulmuştur. Farklı zamanlar içerisinde bileşik yük modelleri devreye girip çıkmıştır. Bileşik yük modellerinin kararlılık analizi ve salınım durumları incelenmiştir. Bu benzetim çalışması MATLAB/SIMULINK ortamında gerçekleştirilmiştir. Bileşik yük modeli analizinde 34.5 kV bara gerilimi, ÇBAG çıkış gerilimi, ÇBAG elektriksel moment, ÇBAG d-q eksen stator akım ve ÇBAG d -q eksen rotor akım değişimleri incelenmiştir.  Yapılan çalışma sonucunda kısa süre olarak devre

Investıgatıon Of Effects On DFIG Based Wınd Turbıne Of Composıte Load Modelıng

Abstract

The effects of nonlinear load models on the system are an important issue in terms of power quality. In this study, the effect of nonlinear load models in the grid-connected Doubly Fed Induction Generator (DFIG) based wind turbine was investigated. Exponential, constant impedance, constant current, constant active power (ZIP) and induction motor are used as nonlinear load model. Composite load modeling is consist of exponential-ZIP-induction motor. Composite load modeling is turn on and turns off system within different times. Analysis and stability analysis of the composite load modeling were examined. This simulation study was carried out in MATLAB / SIMULINK environment. 34.5 kV bus voltage, DFIG terminal voltage, DFIG electrical torque, DFIG d-q axis stator current variations and DFIG d-q axis rotor current variations in composite load model analysis are examined. As a result of, it has been seen that composite
