Study On ARM Based Wind Turbine Controller

Because the conventional energy is limited and have serious problem on pollution to the environment, so the utilization and development of renewable energy is seriously needed. Wind power, as a green energy, has been paid more and more attention, the wind power technology is rapidly growing and wildly used in business from recent years.Wind turbine regularly works under no human managing conditions, so the stability and reliability of control system of wind turbine have strict relation with the efficiency of wind turbine. Usually, common computer platforms or PLC are used for the wind turbine main controller, professional wind turbine controller is monopolized by the well-known international wind turbine manufactorers.The researches in this paper, Arm-based embedded Linux platform is valuable in application in the field of wind turbine, as it has taken the advantage of the embedded system and Linux system's open source and redesignable characteristics.Firstly, the theoretics of the wind turbine and control relation and control method is introduced in the article. Matlab&Simulink fuzzy control method has been used for the simulation of pitch control theory. And according to the figure from Simulink, though the wind speed and pitch angle is changing from time to time, a stable output power supply from the wind turbine generator can be get.Secondly, according to the construction of wind turbine main controller, the study of Arm hardware platform, kernel structure of Linux operating system, a process of building a minimum Arm-Linux system has been given.Finally, the application on the platform of Linux, network communication, serial communication has been given. So the controller is able to realize the wind turbine system data transmission, to fulfill the function of controlling the wind turbine.
