PROBLEM TO BE SOLVED: To reduce error detection of a motor malfunction.;SOLUTION: A control device 100 includes a malfunction determination part 160 and a correction part 150. The malfunction determination part 160 determines whether a gas turbine 10 as a motor is malfunctioning according to whether a fluctuation range of output of a generator 20 detected by an output meter 26 is beyond an allowable output fluctuation range. The correction part 150 corrects the allowable output fluctuation range by using the number of revolutions detected by a revolution counter 25 so that the allowable output fluctuation range increases with increasing fluctuation range of the number of revolutions.;COPYRIGHT: (C)2015,JPO&INPIT
