Abstract
PURPOSE: To prevent previously the occurrence of the fault for the units, by predicting and producing the second abnormal degree signal which can be maximum in the subsequent processes among the signals excluding the first abnormal degree signal with every group and based on the changing modulus of the abnormal signal produced at the abnormal degree conversion part.
CONSTITUTION: Plant data D11WDNn showing the present state of each unit are collected with every group of N units and then supplied to abnormal degree signal generation parts 61W6N. Parts 61W6N feature the same constitution, and here generation part 61 is shown. Then abnormal degree conversion parts 111W11l are converted into abnormal degree signals S11WS1l from the present value of plant data D11 and with every data, and the miximum abnormal degree signal is obtained at maximum abnormal degree detection part 21. Then the second abnormal degree signal which can be maximum in the subsequent processes is predicted and produced among the abnormal signals excluding the first abnormal degree signal of every group at abnormal degree prediction part 31 and based on the changing modulus of the abnormal signals produced through parts 111W11l. Thus the occurrence of the fault can be prevented previously for the units.
