The invention discloses an automatic control method for a transformation process of a supercritical or ultra-supercritical unit from a hygrometric state to a dry state. Currently, the dry-hygrometricstate transformation of a/an (ultra-)supercritical unit mostly adopts a manual operation mode. The technical scheme adopted by the automatic control method is characterized in that firstly a reasonable state transformation node is determined; a theoretical coal feeding amount increment required by a boiler is calculated according to process parameters of stable operation of the unit at a hygrometric state before state transformation; the boiler coal amount is gradually increased according to an optimum coal feeding amount changing rate which is determined through a unit feature test in the state transformation process until the theoretical coal feeding amount increment is reached; and at the initial period of the state transformation, in consideration of the delay feature of the boiler, the water feeding amount at the inlet of a coal economizer is reduced by lowering the water feeding flow, so that the state transformation process is accelerated. By adopting the automatic control method, stable transition of the working conditions in the state transformation process is realized; and the change of the unit parameters is slow, so that abnormal phenomena of equipment failure, overheating of heated surfaces or tripping caused by frequent switching of dry-hygrometric state transformation and acute fluctuation of unit parameters are avoided.
