Abstract


With the growing environmental pollution and the increasing scarcity of the Earth's energy, wind energy as renewable green energy has been growing attention, wind power technology has also become a hot research scholars from various countries compete. VSCF doubly fed wind power generation technology for its low cost, high efficiency wind power technology in today's mainstream. This paper first introduces the development status of wind power technology, through the study of the mechanical torque characteristics of the wind turbine and the doubly-fed machine, drawn VSCF wind turbine torque - speed characteristics. Constructed on the basis of analysis of the doubly fed induction generator dynamic mathematical model and its stator flux oriented vector control, double-loop control of active and reactive power decoupling control scheme. Simulation using MATLAB / SIMULINK platform, and verify the correctness of the control program, with some guidance on the actual system hardware and software design and debugging. Dual PWM converter topology and basic principles of the doubly-fed generator excitation power of in-depth research, focusing on the mathematical model of three-phase PWM converter in synchronous dq coordinates. With current coupling, grid voltage feedforward compensation control strategy and dual PWM converter with input and output characteristics, harmonic energy of the two-way flow of simulation. And VSCF doubly fed wind power generation operation research extended to the run control grid under fault conditions. Established taking into account the failure of the grid voltage VSCF doubly fed wind power generation system complete simulation model. Then \Finally, the simulation based on the design of a double-fed wind power simulation system based on DSP, the system uses a 5.5kW generator wound rotor induction motors do, the use of dual-DSP control network side and rotor-side converter detailed papers describes the design of the voltage and current signal detection circuit, the communication interface circuit, the quadrature encoder pulse circuit and the protection circuit, and gives the main flow of the control program. In summary, the results of this study VSCF doubly-fed wind turbine control system designed to provide a theoretical basis for the simulation results verify the correctness of the theoretical research of this article.
