Abstract
|
Permanent magnet direct drive wind power system is studied in this paper and the theme is modeling and simulation. Analyzed the characteristics and operation of wind turbine and he basic principles of permanent magnet motor rotor field oriented vector control. The direct drive wind power system model of the structures is simulated.The characteristics of wind turbine are simulated based on the wind characteristics and the feature of wind power capture. The method of permanent magnet rotor field orientation vector control is analyzed, and the control structure of design a permanent magnet motor vector control is designed. The simulation summarized characteristics of permanent magnet motor control.The basic principle of network-side converter is introduced. Combined with wind power generation system requirements, the simulation shows the load impact of change on the network side of the converter and DC voltage has a good stability. The wind without detection of the maximum wind speed tracking control scheme is analyzed, the motor-side converter and grid side converter control strategy is analyzed also. The direct-drive permanent magnet wind power generation system is simulated. Simulation results show that the system can achieve variable speed constant frequency operation, demonstrated various aspects of the control strategy in the system correctness and feasibility. Finally, the experiment of network side of the converter is operated based on the TMS320LF2812 DSP core and results showed better.Figure [66] table[3] reference[46]
