Abstract: Two-stage matrix converter (TSMC) has a real DC link, while it does not contain large
DC link energy storage capacitors. Thereby, we introduced TSMC as an excitation source of
doubly-fed wind power generation system, and established a control system of doubly-fed wind
power generation based on the stator flux linkage orientation. Moreover, we developed a
proportional resonant (PR) control strategy used in rotor converter according to principle of PR
control. In this method, the active and reactive current components in the vector control strategy
are adjusted after transforming into a stationary coordinate to realize the doubly-fed generator
