The Performance Evaluation and the Optimal Design of 2MW DFIG

2MW급 DFIG 최적 설계 및 성능 평가에 관한 연구

The optimal design and characteristic analysis of Double Fed Induction Generator(DFIG) was performed. The purpose of the paper is to verify the accuracy of design and the reliability of DFIG by experiment. A grid connection experiment is performed to confirm generating performance in wide operating range. In this experiment, 2.7MW M/G set is used. The finite element method is applied to calculate parameters and characteristic analysis of DFIG. And in order to reduce design time and efforts, Design of Experiment(DOE) is used. The experimental results are compared with the optimum design results.
