Disclosed is an emergency feathering control method for a wind generating set. After emergency stopping of the wind generating set, variable rate stopping strategies are adopted. When emergency stopping is just started, feathering is conducted fast so as to reduce the forward load, and after the blade pitch angle reaches the limited angle or time reaches the limited time, the feathering speed needs to be decreased so as to reduce the negative direction load. The emergency feathering control method comprises the following steps that (1) the variable rate stopping demarcation point of the wind generating set is determined; (2) the system state of the wind generating set is monitored; (3) a variable blade execution system mode of the wind generating set is determined; and (4) the wind generating set conducts variable blade operation according to the variable rate stopping mode adopted by a variable blade execution mechanism.
