The invention provides a power generation frequency testing method and device for a pump station synchronous motor, and relates to the technical field of station operation management and electromechanical frequency conversion. The method comprises the following steps: connecting a synchronous motor to be tested into a power grid and controlling the synchronous motor to operate in a power generation mode, wherein the synchronous motor is a synchronous motor in a pump station; measuring the actual power generation power of the synchronous motor; according to the actual power generation power, connecting an electricity load matched with the actual power generation power to the low-voltage side of the station transformer; and adjusting the load value of the electricity load to obtain the adjusted load value, and determining the target power generation frequency of the synchronous motor according to the adjusted load value and the actual power generation power. In the application, the above steps are executed on t
