<p>PROBLEM TO BE SOLVED: To accurately detect the abnormality of a plant equipment while considering the running state of a plant. SOLUTION: The plant controller is provided with a displacement variable specification part 17 for specifying the normal displacement variableΔCs of a rotor coil inter-pole connection part corresponding to the rotational frequency N of a generator by referring to the characteristic of an equipment, the normal displacement variableΔCs of the rotor coil inter-pole connection part which is specified by the specification part 17 is compared with a displacement variable A detected by a gap sensor 13 to detect the abnormality of the rotor coil inter- pole connection part.</p> |
