In this paper, a black-start strategy is proposed for wind turbines as the main power supply, without relying on the external circuits of energy storage converters and diesel generators or energy storage equipment, without any external circuits in the main circuit, and the process of establishing AC bus is realized by adjusting the starting mode of the converter and improving the control strategy. In addition, this paper combines the virtual synchronous machine control in the network structure control strategy and improve the system stability. At the same time, the impedance model of the grid-side converter is established to analyze the stability of the system. Finally, the effectiveness of the direct black start strategy is verified in the Matlab/Simulink simulation platform.

In this paper, a black-start strategy is proposed for wind turbines as the main power supply, without relying on the external circuits of energy storage converters and diesel generators or energy storage equipment, without any external circuits in the main circuit, and the process of establishing AC bus is realized by adjusting the starting mode of the converter and improving the control strategy. In addition, this paper combines the virtual synchronous machine control in the network structure control strategy and improve the system stability. At the same time, the impedance model of the grid-side converter is established to analyze the stability of the system. Finally, the effectiveness of the direct black start strategy is verified in the Matlab/Simulink simulation platform.
