Doubly-Fed Wind Turbine Mathematical Model and Simulation

With the deepening of the concept of sustainable development, wind power as a renewable energy has been rapid developed. The simulation of wind power generation system in wind power system analysis, power analysis and power grid energy analysis in both played a very important role. In this paper, by using the MATLAB software, the power electronic system mathematical model related to the wind speed, wind wheel, driving mechanism, power generator, and wind power is established and the research of simulation is carried out, which are used for analysis of simulation results. This paper introduces the control technology of wind turbine, which is mainly about variable pitch control and generator speed control, and this paper carries out the simulation of pitch control system and below-rated and above-rated wind speed variable speed wind power system by using the software of MATLAB. It also makes the simulation about doubly-fed induction generator DFIG decoupling control.
