A method for establishing a three-dimensional full wake flow model of a wind turbine in a yawing state comprises the steps that according to the flow field mass conservation theorem and the momentum conservation theorem of the yawing wind turbine and through analogy of the normal operation state of the yawing wind turbine, relevant parameters of wake flow of the yawing wind turbine are obtained; a wake flow oblique angle expression of a far wake flow area of the yawing wind turbine is obtained by solving a conservation equation of each component of wind wheel induction force, and the wake flow oblique angle expression of the far wake flow area of the yawing wind turbine is calculated by combining an empirical formula of an initial wake flow oblique angle at a wind wheel and utilizing a hypothesis of wake flow linear offset of a near wake flow area and a definite integral of the far wake flow area according to the oblique angle. Wake flow center offsets at different downstream positions ...
