PURPOSE:To save energy from the long life of a gas turbine, by estimating an operation time in each operational process or a number of times of operation from a detection value of the change of status in a gas turbine process and outputting the operation time or the number of times of operation with a limited value. CONSTITUTION:A digital signal of gas use, oil use, base operation and peak operation in a plant 1 is input to a status register 5 of an information processor 4 via a relay circuit 2 and process I/O device 3. While a logical arithmetic circuit 6 obtains status of gas base operation, gas peak operation, oil base operation and oil peak operation, to input the status to an arithmetic circuit 22 through a logical value register 7, scanning circuit 8 and register group 9. Further the circuit 22 indexes a constant table 18 to output its arithmetic result to an output device 24 through an output circuit 23 as maintenance information. In this way, adequate maintenance work can be performed. |
