Design Of Main Control System Of Wind Turbine Based On DSP Processor

Wind power generation technology is widely used in the field of energy at present. Because the wind is not only a pollution-free renewable energy, but also has the advantage of extremely high social benefit,With the progress of science and technology,computer and programmable control of the level of scientific research in ascension,for wind power control research provides a new way. The main controller plays an important role in wind power control.While the control system of wind generator at present is mainly based on PLC,for the shortage of its high cost, poor compatibility and hardness in extension development, a set of control system of wind generator with affordable price, excellent compatibility as well as high reliability based on DSP is developed in the thesis.Combined with wind power control technology effectively,research and development of DSP technology is made in this thesis. Design of peripheral hardware based on DSP, application software based on DSP/IBOS platform and remote monitoring software based on QT platform is introduced as key points in the paper.The processor of wind generator controller system is TMS320C6713 chip produced by TI company,with SDRAM and NAND FLASH expanded as peripheral memory and Ethernet communication interface, serial port, the CAN interface and USB communication interface as peripheral circuit. According to the control function of wind generator, data acquisition circuit of wind speed as well as wind direction and drive circuit of each interface module is also designed in the thesis. Operating system DSP/IBOS in development environment CCS5.3 acts as the core platform of application software of the control system in wind generator and device driver and application software is researched and designed as well as remote monitoring system based on QT platform is developed. The work includes configuring the DSP/IBOS operating system, completing design of program in draught fan control, TCP/IP communication node module application, CAN node module application, remote monitoring system, etc.Wind generator controller system in the design can control the draught fan reasonably through the real-time parameters including wind speed, wind direction and temperature through the collecting draught fan, and the excellent human-computer interaction is achieved. Experiments show that hardware part of the wind generator controller system can operate reliably while software part shows a strong scalability and portability. In the aspect of software design,system can not only modify the technological parameters in the operation of draught fan in time according to the problems appeared in the process of fan operation,but also do the real-time display of various parameter values and state in drought fan operation.
