Research on Modeling and Simulation of Doubly Fed Induction Wind Turbine Based on Matlab/Simulink

Abstract

This paper first introduces the structure of doubly-fed wind power generation system and the working principle of doubly-fed induction generator in detail, and establishes the corresponding mathematical model of doubly-fed wind power generation unit. The control part of wind power generation system based on doubly-fed induction generator includes rotor side control and stator side control. The rotor side control adopts the vector control strategy based on stator flux orientation of the double-fed induction generator connected to the grid, and the working principle is analyzed in detail, and the main part of the simulation modeling is given. Stator side control adopts vector control strategy of grid-connected inverter control, and its working principle is analyzed in detail, and the main part of simulation modeling is also given. In order to verify the correctness and feasibility of the system, the simulation experiment platform of doubly fed wind turbine under this control strategy is built by using Matlab/Simulink simulation platform, and its simulation analysis is carried out in detail.
