摘要：

Based on the multi-loop theory, the mathematical model of DFIG (Doubly-Fed Induction Generator) with SWITSC (Stator Winding Inter-Turn Short Circuit) and its MATLAB/Simulink simulation model are established. The MATLAB/Simulink simulation proves the correctness of the established mathematical model. The dynamic response to grid voltage dip is compared between healthy DFIG and DFIG with SWITSC. Results show that, the DFIG with SWITSC has lower active power, less rotational speed, worse reactive power support to grid voltage dip and degraded stability; the worsening situation is more obvious when SWITSC and grid voltage dip become more serious, which provides the theoretical support for the low-voltage ride-through analysis of DFIG with SWITSC. © 2016, Electric Power Automation Equipment Press.
