Abstract
A control method and a control apparatus of a permanent magnet generator are provided, the control method includes: determining an active current reference initial value and a reactive current reference initial value of the permanent magnet generator in a current control period; searching, based on the active current reference initial value and the reactive current reference initial value, and with a target of maximizing a torque-current ratio in the current control period, an optimal active current reference value and an optimal reactive current reference value in the current control period; controlling, based on the optimal active current reference value and the optimal reactive current reference value, the permanent magnet generator to operate; in which the torque-current ratio is calculated based on a torque command value received by the permanent magnet generator from a wind turbine main controller and an output current value of the permanent magnet generator.
