| description | The invention discloses a wind turbine generator control method. The wind turbine generator control method comprises the steps of: S01, monitoring preset parameters in real time, and when the preset parameters are smaller than a preset first standard value, performing short circuit on a stator, wherein the preset parameters comprise a rotating speed or/and a torque; S02, when the preset parametersare between a preset first standard value and a preset second standard value, switching the stator into star connection; and S03, when the preset parameters are greater than the preset second standard value, switching the generator switches into triangular connection. The invention further discloses an electrical system which comprises a control unit, a generator, a converter, a first switch, a second switch and a third switch, a stator of the generator is connected with a power grid through the third switch, one end of the first switch is connected with the stator of the generator, and the other end of the first swi |
