The art of modeling and simulation of induction generator in wind generation applications using high-order model

Both fixed-speed squirrel-cage induction generators and variable-speed doubly fed induction generators are used in wind turbine generation technology. Modeling and simulation of induction machines using vector computing technique in Matlab/Simulink provides an efficient approach for further research on wind generation system integration and control. In this paper, the vector computing technique is applied in modeling and simulation of induction machines. Free acceleration of squirrel-cage induction generator, active power and reactive power control of DFIGs in a power system as well as inter-area oscillation damping control are demonstrated using the proposed model. The modeling approach in Matlab/Simulink makes controller design and Simulation verification effective. (C) 2008 Elsevier B.V. All rights reserved.
