2017 International Conference on Technological Advancements in Power and Energy ( TAP Energy), 2017
In present scenario, the Doubly Fed Induction Generator (DFIG) is contributing more than 50% in wind power generation. The computation of core losses and copper losses are essential to analyse the electric machine performance. In this paper, DFIG is modelled and analysed using ANSOFT MAXWELL which results in distribution of magnetic flux and magnetic ...

IEEE Transactions on Industry Applications, 2016
This paper proposes the dynamic voltage and current assignment (DVCA) strategies for doubly fed induction generator (DFIG) wind power system, which is fed by nine-switch converter (NSC). With the proposed DVCA strategies, the voltage and current capacities of switches in NSC are dynamically assigned to the rotor- and grid-side branches, depending on ...

2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015
This paper proposes a Doubly-Fed Induction Generator (DFIG) Wind Power System, which is driven by the novel Nine-Switch Converter (NSC). Considering the switches in the NSC are shared by two three-phase ports, a new adapted control method is proposed to flexibly control and fully use of the current capacity of the switches.

This paper has an experimental discussion on low-voltage-ride-through (LVRT) capability of a phase-shifted-PWM STATCOM using the modular multilevel cascade converter based on single-star bridge-cells (MMCC-SSBC). The cluster-balancing control, that produces a significant effect on the LVRT capability, is modeled and analyzed with focus on either low ...
