A stator blade heating system is to heat a hollow stator blade of a steam turbine, and includes: an electromagnetic coil disposed within a hollow portion of the stator blade; and a heating device electrically connected to the electromagnetic coil and capable of supplying an alternating current to the electromagnetic coil. A core wound with the electromagnetic coil is disposed within the hollow portion of the stator blade. The stator blade heating system further includes a regulator that regulates output of the alternating current of the heating device, and a temperature sensor that detects temperature of the stator blade. The regulator regulates the output of the heating device on the basis of the temperature detected by the temperature sensor.
