Power-generation control device for detecting abnormality in power generator

In a power-generation control device, a voltage regulating unit regulates an output voltage of a power generator to a preset target level. When at least one of a plurality of types of abnormalities occurs in the power generator, an abnormality detector detects the at least one of the plurality of types of abnormalities occurred in the power generator. The abnormality detector allows detection of the plurality of types of abnormalities that are possible to occur in the power generator. A transmitter creates an alarm signal to thereby transmit, to an external device, the alarm signal. The alarm signal includes information indicative of the at least one of the plurality of types of abnormalities detected by the abnormality detector.
