Control method and device for double-wind-wheel wind energy conversion device

The invention provides a control method and device for a double-wind-wheel wind energy conversion device, electronic equipment and a storage medium, and the method comprises the steps: adjusting the control modes of a front wind wheel and a rear wind wheel under the condition that a preset off-grid condition of the double-wind-wheel wind energy conversion device is met or a maintenance instruction is received, and reducing the rotating speeds of the front and rear wind wheel motor sets according to off-grid reference rotating speed curves corresponding to the front and rear wind wheel motor sets, and when the current rotating speeds of the front and rear wind wheel motor sets are both smaller than the specified rotating speed, disconnecting the first machine side converter and the second machine side converter, and starting the first mechanical brake and the second mechanical brake. According to the double-wind-wheel wind energy conversion device, the front wind wheel motor set and the rear wind wheel motor s
