PURPOSE:To estimate a trouble affecting range of a plant with higher accuracy by knowing a range where the trouble effect reaches assuredly and a maximum trouble affecting range from the trouble affecting relation among devices, the information on the trouble detection of a sensor and the trouble detecting time point and displaying both ranges. CONSTITUTION:A plant 101 includes its component devices 102 and sensors 103, and the detection signals 105 of sensors 103 are supplied to the corresponding trouble detectors 106 of a trouble detecting equipment 107. Then the signals 108 showing the normal or abnormal states are supplied to a trouble affecting range estimating device 109. The device 109 displays a range where the trouble effect reaches assuredly and the maximum trouble affecting range at the estimated time points supplied from an operator console 110 on a display device 115 based on the type of the trouble, the trouble generated time point as well as the trouble affecting direction and the maximum and minimum trouble affecting times given from an initial data input device 112. |
