Design of double fed wind power grid connected control system
Abstract： Design of grid connected doubly fed wind power generation control system, which doubly fed wind power generator is actually a wound rotor motor, due to the stator, the rotor can be feed to the grid, so-called for doubly fed. By changing the excitation frequency and power angle of the motor, the speed of the motor can be changed, and the speed of the motor is achieved.. The frequency of the generator, the voltage grade, the phase and the phase of the grid, the voltage grade and the phase of the grid are the same as the grid connected in parallel.
  The grid connected doubly fed wind power generation control system design as the theme. First of all, to establish the mathematical model of doubly fed induction generator (DFIG) and excitation converter under ideal grid voltage, provides the theoretical basis for the research of the whole system. The design of the network side by the grid voltage directional research to the grid side converter application of voltage current double closed-loop control mode, rotor side converter application power current double closed-loop control mode. Secondly, the control method of the grid side converter, the rotor side converter and the DFIG space vector modulation (SVPWM) technology of the doubly fed wind power generation system are simulated and verified.
Keywords: doubly fed wind power generation system； SVPWM technology；vector control；coordinate transformation；voltage ring；power ring
