Wind Power Simulation System Based on Matlab

Abstract Wind energy is a kind of renewable energy, also a kind of new energy source。 Nowadays, there is a shortage of energy around us, thus the wind energy becomes more and more important, and attracts the attention of the countries all over the world gradually。 Wind power clean is pollution-free and won't produce greenhouse gases。 Compared to these resources as coal, oil and natural gas, it is inexhaustible and unlimited。 So wind power generation has been developed rapidly。 The cost of wind power operation is low and the wind power operation itself can be constructed in large-scale to improve the efficiency of power generation。

Firstly, this article introduces the current situation of wind power at home and abroad, as well as the development prospect of it。 Secondly, it analyses the main composition of wind power system and the conversion process from wind energy to electrical energy through wind turbines, engine room, tower, generators and other part。 It also introduces the main modules of wind power system and its function。 Finally, MATLAB/Simulink simulation software is used to establish the model of wind power generation system control and the wind power generation system is simulated, and the simulation results are analyzed。 The simulation of wind power generation system is of great significance to the development of wind energy and wind power generation。

The paper has 19 figures and 10 tables with 28 references。
