Embodiment Construction
[0067] Such as figure 1 As shown, in this embodiment, the doubly-fed wind power generating set includes: a DC bus, a rotor-side converter, a doubly-fed wind power generator, a power grid, and a processor module; the processor module includes: a phase-locked loop, a PR regulator, a second One PI regulator, the second PI regulator and SVPWM module; the grid is connected to the stator of the double-fed wind turbine through the transmission line; the rotor of the double-fed wind turbine is connected to the rotor-side converter through the transmission line; the double-fed wind power generation The basic working principle of the unit is: the processor module controls the rotor-side converter by modulating the control signal, and then the rotor-side converter inverts the DC bus voltage into a three-phase AC current and injects it into the rotor side of the doubly-fed wind turbine generator. Realize the control of the doubly-fed wind power generator, so that the stator of the doubly-...
