The invention relates to the technical field of aerospace craft manufacturing, and discloses an electric control propeller speed regulator, a propeller speed regulation method and a turboprop aircraft, the electric control propeller speed regulator comprises an oil supply mechanism, a transmission shaft, a worm mechanism, a stepping motor and a control piston; wherein the control piston is located in the transmission shaft; the outer wall of the transmission shaft is provided with a plurality of oil leakage holes of engine lubricating oil. The oil supply mechanism is used for supplying lubricating oil to the propeller through the oil leakage hole; the worm mechanism is connected with the upper end of the control piston, the stepping motor is used for driving the worm mechanism to move up and down, the control piston moves along with the worm mechanism, and the movement direction of the control piston is consistent with that of the worm mechanism; the stepping motor drives the control piston to adjust opening and closing of the oil leakage hole. The electronic control propeller speed regulator integrates the electronic control speed selection function and the electronic control propeller reversing control function, and electronic control over the engine and the propeller is achieved.
