The invention discloses an automatic pump combination control method for steam feed pumps of a boiler feed water system, and belongs to the technical field of control of thermal power generation feed water control systems. The problems that only control over the pressure difference and the rotating speed of the steam feed pumps is considered in the automatic pump combining process of the steam feed pumps of an existing boiler feed water system, and adjustment balance of the outlet flow in the automatic pump combining process of the two steam feed pumps is not considered are solved. When the system meets the condition of starting automatic pump merging control, a water feeding pump to be merged into the boiler water feeding system is started; gradually increasing the rotating speed of the to-be-merged water feeding pump, and calculating the pressure difference between the pressure of water at the outlet of the to-be-merged water feeding pump of the boiler water feeding system and the pressure ...
