Double-feed wind turbine generator subsynchronous oscillation suppression method based on reactive machine-network coordination control

The invention provides a double-feed wind turbine generator subsynchronous oscillation suppression method based on reactive machine-network coordination control, and relates to the technical field ofdouble-feed wind turbine generator grid-connected control. The invention aims at solving the problem that a double-feed wind power series compensation system causes subsynchronous oscillation. According to the double-feed wind turbine generator subsynchronous oscillation suppression method based on reactive machine-network coordination control disclosed by the invention, a double-feed wind turbinegenerator stator side sends out inductive reactive power, and a network side converter absorbs the equivalent inductive reactive power, so that the reactive power is cycled in the double-feed wind turbine generator, and the subsynchronous oscillation can be effectively suppressed. On the one side, the reactive power is cycled in the double-feed wind turbine generator via a reactive machine-network coordination control str
