A power control method for a wind generating set, comprising: acquiring an ambient temperature, rotational speed, and pitch angle of the wind generating set during running (S101); determining electrical boundary power of the wind generating set according to the ambient temperature and the rotational speed (S102); determining stall boundary power of the wind generating set according to the ambient temperature, the rotational speed, and the pitch angle (S103); determining set power of the wind generating set according to the electrical boundary power and the stall boundary power of the wind generating set (S104); and controlling output of the wind generating set according to the set power (S105). The set power of the set is adjusted according to the ambient temperature, the electric generating capacity is improved when the temperature is low, and the safety of the set is ensured when the temperature is high, thereby improving the competence of the set. Also involved are a power control device for a wind generat
