The invention relates to an intelligent synchronous switching water supply system of a motor based on a steam turbine generator unit. The intelligent synchronous switching water supply system comprises a steam turbine, a generator, a condenser, a deaerating chamber, a front pump, a booster pump, a water supply motor, a water replenishing motor, a central control module, a first speed regulating device, a second speed regulating device and a third speed regulating device. According to the intelligent synchronous switching water supply system, the steam turbine and the motor are connected with the water supply pump through the speed regulating devices. When the motor drives the water supply pump, the speed regulating device on the main steam turbine side regulates the oil pressure of a coupler, and the main steam turbine is separated from the water supply pump. When the main steam turbine drives the water supply pump, the speed regulating device on the motor side regulates the oil pressure of the coupler, the m
