The modeling and simulation of the doubly-fed wind power system is very convenient for its operation principle,fault diagnosis and prediction.Based on the analysis and theoretical explanation of the mathematical model of wind power system,the simulation model under normal dynamics is established in Matlab/Simulink,and the simulation of rotor short-circuit fault is realized by adding fault block.By encapsulating the model as a whole with Mask and designing its GUI and code generation methods increase the convenience and portability of the model,and facilitate the simulation of systems with different parameters and implementations in conjunction with embedded systems.The simulation results show that the model built in this paper has good rationality and applicability,which could simulate the actual operation of the doubly-fed wind power system well.The research provides a good model foundation for the research of wind power system.
