Abstract


Wind power is the main force in the renewable energy , environmental protection and sustainable use of the advantages . In recent years, wind power converter and control methods have been studied extensively at home and abroad and hot applications , the performance of the pros and cons of wind power generation and grid operation of the system efficiency and stability play an important role . And grid-connected wind power generation system in three typical main circuit structure , including the the asynchronous generator grid main circuit , the doubly-fed generator grid main circuit and synchronous generator grid main circuit , analysis of each of the main circuit working principle , applicable occasions and performance characteristics. Comprehensive comparison of options synchronous generator grid of the main circuit and system overall composition of the program . Paper to conduct research into the grid inverter direct current tracking control method based on , focusing on the design based on voltage space vector coordinates transform the inertial current tracking control method . TMS320LF2407A DSP as the control core , about level conversion , I / O interface , signal detection and conditioning , keyboard and display , drive and protection hardware circuit design . A simulation study on the design of the system structure of the program and control method , and , on this basis , to complete DSP system control software design and experimental testing , software programming modular structure , including signal detection conditioning modules , SVPWM generation and output module , the system control module and the keyboard and display management module . Through a large number of simulation studies and experimental results confirm the correctness and feasibility of the system structure and control program .
